Originally, I had "purple screen - HDCP erros" between the Roku Ultra and an expensive LG OLED TV that required disconnecting HDMI cables, swapping them, the ports I used, and powering off equipment - until I gave up and called for a replacement "Ultra" STB. Roku relectantly replaced it - only to have the same problems (which I suspect they know about). I eventualy gave up on the Ultra insisting that I get my exercise every night doing this nonsense and decided that a 4K Streaming Stick would eliminate the need for multiple HDMI cables that Roku Support suggested I change out.
The stick solved the HDCP issues; however the Audio Sync issues became the concern - and has been / still is present on EACH and EVERY Roku streamer / device / TV. Roku Support plays the same response to everyone: "What is the model, serial number, blah, blah, blah.." I haven't seen anyone say their problem has been fixed - instead, they just stop posting and complaining because they've come to realize that Roku doesnt have a permanent, workable fix! News flash - these same problems exist for Chromcast and Fire TV too.
Roku Support strings evetyone along by suggesting there is a fix - but they need 'more information" (a.k.a. time) to have their engineers look at YOUR problem (it is unique - no one else is having your problem!). They do this until the warranty return window for the streamer / device / TV has closed. Roku has been doing this for YEARS and it has likely become part of its mission statement. Its frustrating but it is what it is.
If my sync problem can't be fixed, using HDMI eARC, I'm sending back my new ROKU TV that not a week old. I'm not going threw these 4 steps every time I change a channel or switch from TV to streaming. This is BS.
I am experiencing the audio delay issue with my new Roku TV 50R4A5R/50R4AX. I am hearing impaired and using a Phonak TV streamer connected via optical port and the sound coming from the TV speakers is out of sync with the sound from the streamer. I'll be returning the TV and trying one with a different OS.
I have updated software several times and had Comcast out to re-run a line to my place to fix internet speeds. The issue goes away if I exit out of the show (without exiting out of the app) and then starting it again. This issue has really only popped up in the past year, but it is consistent and happens multiple times a day.
Have you tried removing the channel that you are experiencing the issue with from the Roku home screen? Then, disconnect your device from power for a minute. Plug it back in, then try to add the channel back once more and see if this clears up the issue.
I have been experiencing exactly the same issues as you with my new Hisense U8H TV and my Roku devices. I have tried both a Roku Ultra and a Roku 4K+ stick and have the same problems. It is only with Xfinity Stream app, which is what I use 99% of the time. I do not have a soundbar. Have tried everything listed everywhere, and, as you, just backing out of the program and going back into it fixes the issue temporarily. This audio synch or volume issue happens multiple times per hour and is very annoying. I have used the same devices on a Panasonic plasma screen TV and have not had the same audio issues. I am ready to chuck the Roku streamers!
In the meantime, please help us with the required details below so we can send additional information for the investigation to our engineering team, and once more information is available I'll be sure to let the Community know:
We understand that you're having a problem with the Xfinity app. I'd love to help you with that. We would like to know what went wrong so we can assist you further and fix the issue, but we need more details.
I have had no issues with my Nebula playing HD content. I also do not experience any audio lag when using HDMI connections, we have used one of my Roku devices, my nether stream box and our laptop to connect to it without issues.
the netflix app that was installed had to be updated right away, afterwards the whole unit had a firmware update and after that netflix again updated and has worked since. maybe check to see if there is a firmware update for your nebula and then try again
I have a Roku 4k device model 3941X that we started using a couple of months ago. Since we started streaming with the Spectrum app on Roku the audio is about half a second ahead of the video on all of our TV's. I still have a cable box attached to one of the TV's with no sync issue when watching through the box.
The problem is only occuring on the Spectrum app, all of our other apps do not have the audio sync issue (Netflix, Apple TV, Disney +, HBO Max, Prime Video). If we watch a program through the cloud dvr, or on demand within the Spectrum app the audio sync issues are not present, the issue is only present when watching regular programming within the Spectrum app. It may be my imagination, but some channels seem worse than others, but only slightly.
I am on a 5ghz wifi system with an excellent signal, and an internet download speed of 103Mbps when checking the connection through Roku. Using a wifi speed test I am consistently getting 396Mbps down and 19Mbps up.
I have tried restarting the Roku device, adjusting audio settings as described in other threads, deleting and re-adding the Spectrum app, restarting both the modem and the router all to no avail. The issue is clearly within the Spectrum app, any help would be appreciated. Thanks
A couple follow-up questions; Have you tried replicating the issue with the app on a different device? Have you tried restarting the Roku from the settings menu (a warm reboot)? Last, have you tried swapping any cabling, including HDMI cables?
Will you please reboot the modem by removing the power cord for 30 seconds before plugging it back in? Wait for the online light on the modem to come on and then reboot the router in the same manner. Allow a few minutes for it to finish rebooting before testing the app.
I have also rebooted the modem by unplugging it for 30 seconds, waiting for the online light on the modem, then rebooting to router by unplugging it for 30 seconds, again with no effect on the audio sync issue
Thanks. The next step is to schedule a service call to have a technician check your signal levels. I was able to locate your account based on your registration information and I see that you have an appointment scheduled in the near future. Since the modem does have log information, please try to avoid restarting the modem prior to the appointment so the technician can see any error logs.
UPDATE!: My new LG G2 77" OLED set is a smart tv that is naturally capable of downloading tons of apps. I decided to just download the Xfinity Stream tv channel app and now I'm directly watching all my Xfinity channels (bypassing the ROKU Ultra box) and there is no more audio sync issue!
I just want to remind everyone else (as I did earlier in my original post) that if you have a Smart TV you can download the Xfinity app directly to your set, and you won't have the audio lag. This bypasses the ROKU box . . . not an ideal solution, but it does work. It needs to be said . . . EVERY other streaming service works perfectly on ROKU . . . except Xfinity. It's not Roku folks . . . it's Xfinity!
It's clear to me Xfinity is treating this issue with little more than an honorable ignorance. They are "claiming" to be working on this issue . . . they are NOT! I'll soon be going to FUBO Streaming. It's cheaper with even more really good popular channels and works perfectly on ROKU!
