X1 Audio - How does it work and what should I expect?

I would, however, like to point out that your concerns are valid when it comes to my Issues in the first post.  For issue 1, there is a known issue today that will force an Arris XG1 box into stereo after a reboot even if it's set to surround prior to the reboot.  Even though the box is outputting stereo audio the user interface still indicates it's in Surround mode.  This is being worked on and will be fixed in the next major release or set top firmware so stay tuned there!  I have tested and validated that this issue is resolved in this next major build as it is in pre-release right now in my lab environment.  Even after this release a user COULD still see the issue I bring up in the first post.  The best way to solve it will be to follow my instructions there.  Neal it should be noted that prior to this bug appearing a few months ago (and the above mentioned Pandora audio bug), the audio on all three of my Arris DVRs worked properly in all situations...

 

 


Yes thanks Rick.  It was about this time when we moved to 1.34 FW revs and began implementing EDID checks for "Auto Surround."

Neal,

Without providing user or tech accessible settings, that was a HUGE mistake...

Hi everyone, 

 

First thanks for all of this discussion about this topic. I've been waiting for a fix to be released.

 

Here's my setup and hopefully one of the Comcast guys can help...

 

I have an Onkyo TXNR-709 via HDMI to the X1 (video device is an Epson projector -- also through the receiver)

 

I am running XRE server version 1.47.18 11/13/2014 14:01

XRE Protocol: 2.8.0

STB Version: PX001AN_1.3.4p3s3 PRODse

and I have a green light (not sure which box that is?)

 


My screen says surround sound, but the receiver says stereo unless I change the output on the X1 to stereo then back to surround (then it outputs surround). It usually lasts until I turn off my receiver and come back the next day -- then we're back to stereo on the receiver, but surround on the screen of the X1.

 

What should my solution be? I don't mind waiting until you push a real fix, but I'd be curious as to which fix applies to me. 

 

THANKS AGAIN.

Actually your fix is easy and it has been discussed in this forum many times. You need an Arris DVR... Arris DVRs detect HDMI audio settings differently.

The problem is you can't request a particular DVR until you register a trouble ticket and get it escalated to tier 2... But it can and has been done.

Hi adam_WM. This is a known issue with the Pace XG1 and will be resolved with our move to 2.0.x firmware soon. Thanks for your patience!

That sounds like I don't have to make changes to my TX-NR626 if I wait for the 2.0.x firmware.

Thanks 2themax.  Are you using hte TV speakers or a soundbar connected from the TV?  I just want to be sure I understand your setup 100%.  Thanks!


ComcastNeal,

 

This is using the TV speakers. The sync issue popped up I think around the time of firmware 1.3.3 if that helps. Also, my BD player and Apple TV do not have this issue on the same TV. I even tried changing the HDMI ports around just in case and that did not help either.

Pace XG1 - Blue Light -> Denon AVR1913 -> Panasonic 65ST50 all via HDMI

 

I usually have to toggle surround back on every day. X1 settings always say surround, but overnight it usually reverts to sending non-surround to receiver and I have to select Surround again in the X1 settings next time I watch. This morning I did not have to toggle it... coincidence? 

 

Also, will the new firmware for the Pace boxes address the audio skips/dropouts? Will the new bitstream option help that?

You know lately I have started getting the Audio skips/dropouts even with the Arris XG1 with the Blue power light. It's very rare but I noticed it with for example with the The Voice On Demand. But in this case it happens every singke time in the same spot. So its in the recording. Been seeing that a lot with On Demand shows.

 

 Hopefully Firmware 2.0 will fix 99% of the audio issues.

Two weekends ago I was at a buddies house that just received a brand new Pace bluey, I noticed three audio skips over three hours of watch TV. I intend to test it further. My buddy is an AV installer so he is watching for it...

However I would like to add I have not heard a legitimate audio skip at my house since I got Arris DVRs...

Watch The Voice OnDemand S7E15 and you may hear the audio skip and drop out.

 

I am watching it now and I already hard 2 drop outs. However if I goback to the same spot the audio drops out every time.

If you can replicate this drop out while watching on demand then it is the broadcast not the equipment. The audio drop outs I am familiar with could not be replicated unless you recorded them.

For me, if I back up via rewind and rewatch the portion that "skipped" it does not show up again. So, mine is the classic skip from equipment not from the broadcast.

I switched to X1 boxes last week and everthing was fine until yesterday.  I lost all audio.  The audio in the TV mode is fine but will not work on the HDM1 mode.  I have a SONY sound bar attached to the television.  What should I do.

I had some of that drop out too, had to delete the shows from the DVR and watch via ON demand copies. Appears to be a one or two day problem all ok again now re: no more audio dropouts.

What I noticed two weekends ago on my buddies Pace bluey is entirely different than what I used to notice when I had a Pace greenie. The issue could be related but I think it's different.

FYI no issues in this regard with any of my three Arris DVRs...

Your box probably did not reboot. It usually just happens after a reboot. However this has been more of an Arris problem then Pace. Wonder if we are talking about the same thing?

I can assure you that at least in the case of Arris boxes NOTHING has been fixed.

What X1 box and firmware do you have?

 

Because I just restarted my Arris box with the blue power lighn that is connected to my Denon 1610 5.1 AVR and the surround Sound went off again and says Stereo even though of course at the same time under the X1 audio settings it still says Surround Sound Smiley Sad

 

So not fixed for me yet but then again I do not have the new 2.0 firmware yet so not really surprised.

Hi ComcastNeal.

 

I have a new issue that I just now noticed and maybe you can help me with that too.

 

On my Pace box named "Mike's Bedroom" While playing some but not all DVR Recordings and bring up the Apps and click on the My Account App I can see the video freeze and peeking though in the backround instead of a solid black backround and when I exit the apps my DVR recording continues playing with no sound. And if I stop the recording and switch to another live channel I still have no sound. And the only way to get sound back I need to reboot the box by unplugging it.

 

Now I have tested this on my other 2 DVR boxes with the same recordings and neither of thiose 2 boxes have this issue. On those 2 boxes while playing the same recordings if I bring up the Apps then My Account App the backround gets solid black with no sound and when I exit out of the Apps the recording starts playing and I get sound.

 

Can you fix this or do you think the Mike's Bedroom DVR box maybe going bad and I need to replace it?

 

Thanks

i'm getting this too repeatedly still on .17 so i think it is a server message to my box error. also gets tiny picture on playback in upper left hand corner for a second or so . On the sound you can change resolution (exit exit exit 480) then sound returns can change back exit exit exit 1080 and sound stays. The audio 'leading' the video (lagging behind audio) after trick play is getting worse and worse (happenning more and more often).

ComcastNeal,

 

I have not seen the REAL issue mentioned here in regards to Surround reverting back to Stereo, so here it is:

 

The X1 box reboots nightly (or at least most nights).  When it reboots, the downstream equipment (AVR) is typically turned off.  When the X1 comes back online it does the HDMI EDID check/handshake and doesn't "see" a surround-capable device since the AVR is powered off.  It then reverts to outputting a Stereo signal over HDMI, and it apparently never re-negotiates with the AVR after the initial power-up of the X1 box.  This is a huge problem for a box that reboots nightly when most people's equipment is turned off!  None of my other equipment behaves like this - they all re-do their HDMI handshakes when other equipment is powered on!

 

I can recreate this issue 100% of the time if I reboot my X1 box while the AVR is powered off.  If I reboot the X1 box while the AVR is powered on, the X1 box continues to output surround sound after rebooting (since it "saw" a surround-capable device).  Perhaps that's why this is taking so long to fix - you are testing while the other equipment is powered on which is not realistic since the X1 reboots at night.  The X1 should be doing another HDMI handshake when the AVR is powered on, but it's not.  Until this happens, the problem will never be correctly fixed.  Either that, or just output forced surround when the customer selects "surround" in the menu and do not do an HDMI-handshake to check if the device is surround-capable.

 

Also, when surround is being output from the X1, I have multiple split-second audio dropouts per hour (probably anywhere from 3-8) when watching live TV.  I never once noticed these dropout issues on my old Motorola DCX3400.  I also don't really seem to notice the dropouts if I set the X1 to output Stereo instead of Surround.  Are the Surround dropouts being investigated by the X1 team?  They are so annoying that I currently have Surround sound disabled on the X1 box.

 

I have the blue light Pace DVR for what it's worth.

 

Thanks!

I can recreate this issue 100% of the time if I reboot my X1 box while the AVR is powered off.  If I reboot the X1 box while the AVR is powered on, the X1 box continues to output surround sound after rebooting (since it "saw" a surround-capable device).  Perhaps that's why this is taking so long to fix - you are testing while the other equipment is powered on which is not realistic since the X1 reboots at night.  The X1 should be doing another HDMI handshake when the AVR is powered on, but it's not.  Until this happens, the problem will never be correctly fixed.  Either that, or just output forced surround when the customer selects "surround" in the menu and do not do an HDMI-handshake to check if the device is surround-capable.

 

Also, when surround is being output from the X1, I have multiple split-second audio dropouts per hour (probably anywhere from 3-8) when watching live TV.  I never once noticed these dropout issues on my old Motorola DCX3400.  I also don't really seem to notice the dropouts if I set the X1 to output Stereo instead of Surround.  Are the Surround dropouts being investigated by the X1 team?  They are so annoying that I currently have Surround sound disabled on the X1 box.

 

I have the blue light Pace DVR for what it's worth.

 

Thanks!


This post is basically my exact issues... also with the Pace Blue Light. The dropouts are getting worse lately, not better.

Comcast Neal,

You are a veteran of the AV industry just as I am. I am trying to think of any AV source component that "auto negotiates" audio over HDMI like X1 boxes do. I am not sure that I have ever encountered an AV source unit that auto negotiates the audio. I suspect Comcast did this in an effort to cut down on service calls but I have a feeling it backfired. Personally I think some extremely poor decisions were made and nobody from Comcast has owned up to them.

Auto negotiation of audio is one thing. But doing that without user or tech accessible settings is COMPLETELY unacceptable and I would love to talk to the Comcast bean counter that made this decision.

You have told us that new firmware is on the way. I DEMAND that this new firmware not be released unless user accessible HDMI audio settings are added or auto negotiation of audio is defeated.

I find it hard to believe this would not save Comcast a fortune in service calls.

Good idea RickGr4!  Why not just give us the option to choose "Stereo", "Surround" or "Auto" in the menu and forego the HDMI negotiation altogether for those that explicitly select "Stereo" or "Surround"?  The problem would then be solved!

 

Well, the problem would be solved once Comcast addresses the surround audio dropouts that is.

Thanks but I've known about this for almost a year now and I have mentioned it in this forum regularly...

It is possible there is a new audio drop out problem occurring. I have a friend that just got an X1 Pace bluey. I will be at his house this coming Sunday and I intend to observe carefully for this issue.

I have never had the dreaded audio drop out issue with any of my three Arris DVRs and as I write this I am still not having any.

Yeah, just make sure his Pace box is ACTUALLY outputting Surround to test for the dropouts.  I don't notice the dropouts when in Stereo and I'd rather have Stereo (which is processed by my AVR as Dolby PL2) without dropouts than Surround with frequent dropouts!

Of course. He has his Pace Bluey connected to a high end AV system.

You nailed it on the head. This is the exact problem I have with my old Pace green light box.

Hi RobertWy.  Sorry for my delays here.  I've been traveling for the last two weeks.  I just checked your Pace XG1 and see that it's downloaded the most current version.  Thanks!

RustyBen, your "Master Bedroom" Pace DVR was the only box that did not update to PX001AN_1.3.4p4s1_PRODse.  It's downloading now.

ComcastNeal,

 

I would appreciate it if you could reveiw and respond to my post #84.  These surround issues are 100% reproducible and Comcast really needs to do something.

 

Thanks!

Hi jkozlow3.  Thanks for your input.  You're correct that the EDID is most likely not passing since the AVR is off at reboot.  The good news is that we're working on menu based options for end users to over ride the "Auto Surround" behavior that today's 1.3.4 firmware supports.  As I've said, the first step is for us to get to 2.0 then from there, things will really change around surround options for ALL X1 set top manufacturers and models.  We won't have every issue taken care of in version 2.0 BUT shortly after you'll see us really start to chip away at everyone's concerns and requests.  Stay tuned!

That's great news Neal.  Are the Surround sound audio dropouts being investigated as well?  Because there's no point in getting surround working properly if the frequent split-second dropouts persist.  At this point, I've got my X1 outputting Stereo which is preferable to Surround + dropouts.

We are aware of the drop out issues and I haven't experienced any in 2.0 test firmware builds on Pace XG1, Arris XG1, RNG150, Xi3, or Pace XG1 v3 boxes.

RickGr4, we understand our current offerings for surround solutions are not ideal and I've made it very clear on the forums that we are working to correct these solutions.  Everyone's feedback and input is greatly appreciated.  Also, I've said that I'm helping to guide the X1 team through these issues and, while I've been with Comcast for several years now, I've only been deep diving with the X1 team fairly recently.  The X1 team has been working on 2.0 firmware long before I started looking into these issues and posting on these forums.  I'm here to help and pass your feedback directly to the X1 team after doing extensive research to replicate issues.  We will continue to develop the 2.0 firmware as planned.  It WILL be pushed to boxes without every issue fixed, but once deployed, we can easily build on it for these and other issues.  2.0 is not being pushed just for surround issues, but many other reasons as well.  X1 is still young and we are learning more every day.  I've explained a few options that will be included after 2.0 and appreciate everyone's patience while we work hard to wrap up initial development of the next big firmware release for the X1 platform!
