Stream App volume fluctuations  (low to really loud)

We have the same issue!  We have Roku soundbar, Roku stick, Roku ultra, and 2 Roku TVs....all have the same sound issues and only on the Xfinity app.

Seems as though this is a known issue without resolution since 10/26.

I would like to see Xfinity provide a fix to us ASAP!

I don’t use a Roku it’s the app. It does it on our tv also. And now the only channels I get on the app across all devices is music and qvc

I'm having the same issues.  It's the Xfinity app.  No problem with other apps.  Come on, Comcast.  Fix the problem already. 

Same problem here.  It happens on 4 makes of tv, all with Roku, only 1 with sound bar.  I have reset tv settings, restarted Rokus, updated software, updated Xfinity app, restarted gateway/router…you name it.  No way to know when it happens.  Exiting then tee terming channel fixes the issue.  Xfinity app is the issue.  

Seeing the same thing in Gettysburg PA across 3 different TV's with ROKU devices.    We also have a Roku Ready TV (TCL) which we've not seen it on,  but we don't watch Xfinity as much on that TV so it's possible it's there and we just have not witnessed it as much.     I can say the we DO NOT see this volume up and down behavior on any other streaming app,  only on Xfinity.   Lastly,  I have no hard proof, only observation, that the problem seems to have begun right around the time the Xfinity Beta switched to the current Xfinity Stream app & icon.   There is clearly a bug of some sort in the app, likely in code that gets reset with a channel change, because I think everyone posting on this topic sees the problem go away with a channel change.   Good luck, Xfinity.   It's a very annoying bug that I'm sure many would like to see disappear.   Thank for your efforts to correct.

Hi, I am adding my name to this list / bumping the thread as opposed to creating a new one.  I realize it appears to be a known issue, but maybe this can help narrow things down for the Engineering team.  Here are the details of my current devices and setup:

• Roku model: 3920X - Roku Premiere (the remote does not have a volume adjuster)
• Roku Software version: 11.5.0. build 4235-91 (not sure if this is of value as this is an Xfinity thread but here you go)
• "Xfinity Stream" app version: 6.9 - build 0
• Description of issue: We own three of these devices, all on same versions referenced above, none of them using a dedicated "soundbar", only the dedicated built-in speakers of the television output.  Each of them, no matter the channel, intermittently adjusts volume "gain" high or low on its own.  What I mean by audio gain is think of something like VLC player (free open source audio software) on a PC.  You can adjust the volume "slider" in the software past your speakers maximum.  One thing I want to make clear is that it is not changing the television's volume adjustment bar on its own, but changing the gain like I mentioned above (software issue).  The fact that this is happening is kind of scary, as it may lead to damaged hardware (blowing out television speakers), damaging the ears of newborns / elderly, etc.  Of course the reverse happens where volume gain goes low, again all intermittent, no real way to replicate. 
• Workaround: The way to resolve either of these gain issues is in my case to simply change the channel you are on.  The channel you switch to will be the expected volume my TV is set to, and quickly swapping back to the channel where the issue happened is back to normal.  Non-ideal!!
  Troubleshooting steps taken: Each Roku is powered off completely after each use.  Uptime on each is low.  Software versions for everything above is latest / greatest.  Different HDMI ports on each television have been attempted, does not stop the issue.  
• Next steps: Keeping an eye on this thread for hopefully a solution or a rollback option...

This thread was one of the highest results for the issue with a search engine.  I urge others who may be experiencing this to please consider adding their name to this list for visibility.  Maybe not as many words as this one, but I just wanted to be thorough.

Thank you for looking into this.  Let me know if anything else is needed on my end.

Same thing here. I was afraid it was my audio equipment (Yamaha receiver). It’s not. It is the xfinity app on Roku. That’s ok, since it is still in Beta. But FIX IT, please.

Also have this issue. Two tv’s with Roku and only the Xfinity app is the issue. Sound goes loud, quiet, crackles and out of sync. Very annoying.  

Happening to me too. Roku Ultra connected to pioneer elite av receiver.

I am having the same issues with sound and it started about 2 months ago.  Volume will go extremely loud and then absolutely no sound.  I have to exit the Xfinity streaming app and go back in.  This is extremely annoying.

I am having the same issue with 4 different Roku Streaming Stick + devices

I'm having the same issue as well. 4 Samsung tv's two with sound bars and two without. The issue started all at the same time. All other application do not have this issue....only in the Xfinity application. 

Hi. I’ve been having the same problem on two TVs both with Roku for several weeks. Sound just fluctuates on its own with a lot of static. This is particularly upsetting when you’re listening with earbuds and the volume suddenly jumps 3 fold. Only happens with the Xfinity app. I have been following this thread for weeks figuring it’s going to be fixed soon, but no luck. Instead of the soothing customer service rep messages and asking numerous customers for the exact same information, could you please just give us an estimate for when it will be fixed. I pay a ridiculous amount of money monthly for cable and often ask myself why because I seldom watch it. But when I do, it would be nice if the sound worked. 

I am also experiencing this same issue -- volume goes from normal to VERY LOUD!!! It is extremely frustrating when you are frighteningly awakened in the middle of the night by the sound of the TV blaring at top volume. It awakens several members of my family and disrupts the sleep of school-aged children. We also use ROKU streaming sticks on multiple TVs and it happens to all of them. THIS IS AN XFINITY ISSUE THAT NEEDS TO BE CORRECTED!! 

Just wanted to echo the same issues for my Vizio TV withe Roku 4K stick connected to a Vizio soundbar, as well as my Samsung TV connected to a Roku 4K Streambar, and Samsung with Roku 4K Stick with just TV speakers. Seems fairly clear that the app is the root cause.
