Playback Video - sound stuttering after March 5th Update

Thanks!
If someone wants to set it:
sudo mcedit /lib/systemd/system/transmission.service

add line under [Service]:
Nice=15 or any number inbetween 20 to -19, higher number means lower priority

I’ll report back if it does anything.

I’m curious to see the results.
From my tests, after transmission downloads a torrent and the service is stopped , the stuttering continues until a reboot is made.

From my understanding this is a kernel network related issue not directly connected to transmission only.

I’m using Sonarr and Radarr and experience the same issue. Usually every couple of minutes the sound drops (video unaffected), although much more frequently if Sonarr/Radarr is actively processing something.

I use HDMI to a Sony A/V, so the dropped sound usually lasts for about 1s while the A/V re-syncs (can see the A/V display drop the audio icon, and then light up again). This happens the same on PCM and Dolby passthrough.

@popcornmix has pointed me to a potential solution, but suggested we wait a little to see if there’s a proper fix instead of simply dropping a commit.

I have been waiting for more than 5 months and have wasted a lot of time troubleshooting my environment. Just recently came across this post and found that rolling back the kernel does work. Wonder how many people are out there fighting this or have given up and moved to something else? I am willing to wait a little but can’t you share the potential solution/work around till the final official fix gets released? If not, does anyone know what a “little” really means as this has been an issue for quite a long time now?

We need to test things first. It could be a week or so.

Thanks for your patience

That is more than reasonable. :slight_smile: Appreciate the quick response.

Hi

Hopefully the issue is now addressed with the following commit:

I’d appreciate it if you could test this and provide feedback before we potentially release this as an update to other users. To test this update:

  1. Login via the command line
  2. Edit the file /etc/apt/sources.list
  3. Add the following line: deb http://apt.osmc.tv stretch-devel main
  4. Run the following commands to update: sudo apt-get update && sudo apt-get dist-upgrade && reboot
  5. Your system should have have received the update.

Please see if the issue is resolved.

I also recommend you edit /etc/apt/sources.list again and remove the line that you added after updating. This will return you to the normal update channel.

I have upgraded and only have single remark right now. After upgrade, a simple reboot only caused it to crash. However, power cycle and everything seems up and working. Will be testing this out and let you know in a couple days, or sooner, if problem returns.

Again, greatly appreciate the quick turn around.

I have applied this on my side as well.
Will revert back as soon as I have a conclusive result.

I am not noticing any improvement watching live tv after around 5 to 10 min using MMAL i start getting massives audio stuttering with omx i do not get that behaviour.

Wondering if my problems is not different and links to
https://github.com/xbmc/xbmc/pull/13993

You can try a Kodi v18 build and see if it fixes it

So far so good here. Will continue to run this and will report back again later.

Looks like that was the fix. Watched a 90 min movie with eac3 sound track and it was flawless. Great job Sam!

This has definitely solved the issue for me. I haven’t had a dropout since I’ve run the dev update. Perfect playback here.
