Xfinity Stream App Audio Out of Sync

Well we cannot stream direct from the app on my tv as it is too old. We have noticed some stations are worse than others. Getting Fubo or Youtube is not cheaper for us, plus Fubo does not have the History Channel and that is a must.. Where we live we are stuck with Comcast internet, so until they offer an internet only option we would then pay for TV services twice. I will not buy a new TV as ours works great and it is only 8 yrs old.  I will join the growing list of subscribers that have contacted Xfinity support and hope that maybe one day they will surprise us.. LOL.

Much like everyone else is saying, the Stream app has gotten almost unusable lately. It seems to be that the video glitches in some way, and the audio carries on seamlessly, resulting in it being very out of sync. Other apps work fine. If I exit the Stream app and start over, it will be OK again for a short while until it eventually gets out of sync again. 

I will add my experience. Same as above - the condition of out-of-sync audio only occurs within the Roku Xfinity Stream app for me - all other Roku apps work fine. And when it happens, navigating back to the Roku home screen and re-starting the app works for a short period of time - sometimes very briefly, sometimes for hours. But the condition currently will reliably re-appear. I hope that Xfinity engineering can identify the problem and release a fix very soon, as we rely on this for a TV which is not located anywhere near a cable outlet.

I have the same issue with xfinity app using roku 4k+ stick and roku 4k stick.

I see thread started Dec of 2022. It is now June 2023 and xfinity app issue still exists.

This all began in December of 2022 and it's now June of 2023.   Over six (6) months of this is beyond ridiculous and Xfinity should be ashamed.  This is NOT a Roku problem, as EVERY other streaming service works perfectly with Roku.  Like so many others, I have repeatedly called Xfinity on this and quite often the staff seem to have zero knowledge this issue even exists.  A few weeks ago I even spoke to a guy at Xfinity technical support who described himself as a senior tech and much to my shock he said he NEVER even heard of this issue!   How can this be?  This very strongly suggests to me that Xfinity isn't working on this AT ALL!   

It's very much looking like they really want everyone to go back to renting their own proprietary boxes, thus increasing revenue.  Xfinity could care less about customers streaming their channels on other third-party equipment.  They're making big bucks on renting their own cable boxes, so it would be a conflict against their own interests to allow a smooth experience via streaming on other third-party boxes like Roku.  I wish they would just be honest and admit to this shameful marketing strategy instead of stringing us all along thinking they're actually working on something . . . they really aren't even looking at!

We are experiencing the same issue for months and it has become progressively worse lately. Leave the channel and come back and it’s fine for a few minutes and then out of sync again. Yesterday we had to do that six times during one 30 minute tv show. Everything works fine on the one tv we have the cable box attached to and other apps we stream through the Rokus are fine, it’s just the xfinity app. We pay quite a lot for the service and were happy at first that we didn’t have to rent a bunch of boxes but this is ridiculous.  Not falling for their ploy to add another 60 bucks a month to get boxes. Going to have to look at other options if it isn’t resolved soon. 

Well, I finally had to throw in the towel with Xfinity tv channels.  I canceled it last night (kept their internet though).  Spoke with a really friendly lady from Customer Loyalty out of Colorado.  She confirmed they were indeed getting a lot of calls about the audio lag.  Told her that after 22 years of being with Comcast/Xfinity, I simply had to move over to FUBO streaming for tv channels.  She understood perfectly.

I got FUBO's Elite channel lineup and man do they have a lot of the really good channels!  The main thing is they come in perfectly on my ROKU Ultra boxes (have one in living room and another in bedroom).  No audio sync/lag issues at all!  Video looks superb.  In an earlier post (see above) I said I had temporarily downloaded the Xfinity Streaming App on to my LG-G2 OLED and for a long time there were no audio sync issues . . . until yesterday!   I was shocked!  The lag issues are now showing up all over the place with Xfinity streaming.  I should have made the leap to FUBO months ago, instead of enduring this ridiculous audio issue.  The lagging started back in December and we're about to go into July.  I simply refused to go into another season putting up with that insanity.

I’ve been having non stop issues with the audio matching up the video. I stream my cable access via Comcast app on Roku. I constantly have to back out of the show and click back to view it again for audio to match up again. On my other TV I stream Netflix and the streaming freezes and makes my tv unresponsive… leaving me to unplug it to restart it. Please note this is after I received several emails about updating my modem due to being outdated in which I did buy a top of the line modem/router combo. I received a note they were going to be upgrading my services in my area… only getting worse.  VERY FRUSTRATING! 

Hi,

Found a temporary fix for the "Lip sync issue with Roku". Bypassed the Roku Ultra by Streaming to computer then Casting to TV. Lip sync issue is gone. Still want this fixed with the Roku Ultra player. All the connections are Ethernet. Nothing is Wireless.

This temp solution works with Cell phone too via WiFi. Samsung phone , Sony 4K OLED TV.

Can't add the Xfinity app to Sony tv's for some reason.

Finally decided I just cannot put up with this issue anymore. We have for now decided to switch to Sling as we just can't put up with the voice lag anymore. Very disappointed. Hopefully one day someone, either Roku or you can get this fixed. But for now I will have to miss watching my favorite MLB team. Yes, I have done all suggestions and nothing works. 

As I reported some time ago right here via several of my own postings along with a lot of others, I too have moved away from Xfinity Streaming TV and gone to FUBU.  Some of you may elect to go to YouTube Live, Sling or something else.  We all tried all the recommended "so-called" fixes for the blatant audio lag issue via Xfinity Streaming with Roku and absolutely nothing worked.  I still have Xfinity Wi-Fi and Xfinity Mobile which I love.   As several other posters here have said, it appeared to them that Xfinity was intentionally trying to get everyone to rent their proprietary Xfinity boxes instead of using third-party boxes like Roku.  I didn't want to believe that at first because the Roku boxes work flawlessly with every other streaming service out there . . . except for Xfinity.  Clearly, the problem is with the Xfinity Streaming app itself.  It originally worked just fine with Roku for years, until Dec. of 2022 when Xfinity did "something" that created the audio sync issue that has lasted for the last seven months now.  If there truly was a desire to fix the issue . . . it would have been done by now.

I was shocked to learn from a friend who works at my local Xfinity Store here in Santa Rosa, CA that the issue is well known within Xfinity and they are indeed NOT addressing the issue because they absolutely don't want to lose revenue from the box rentals!  I was saddened to hear him admit this, but he said it is well known internally within the company that this is the situation.  I think Xfinity should admit to what they have done and stop stringing along so many customers that they're working on a fix.  Some reps even continue to "claim" they know nothing about this issue . . . which is NOT true!  Xfinity is a decent service, but if you want their TV streaming package with ROKU you will simply have to cough up the money for Xfinity's proprietary rental boxes instead.  Xfinity seems to have made a corporate decision that they just don't want to mate with Roku.  The professional thing would be to admit it, but they won't to do so.  Therefore It's decision time for us . . . good luck with whatever your decision may be folks.

My 2 year contract is up next month.  I'm finally dumping Xfinity completely because of this stream app issue.  I'm very excited to be rid of this garbage.
