Description Michael Catanzaro 2021-05-16 11:35:20 PDT

Since 2.32, YouTube videos now sometimes start playing muted unfortunately.

This was partially fixed via bug #223195, but not completely fixed. When the bug occurs, it is now possible to fix by pausing the video and then playing it again.

Since I cannot reproduce on demand, unfortunately I don't have GStreamer logs.

Still broken with the 21.08 runtime (including GStreamer 1.18)

Comment 2 Michael Catanzaro 2021-07-30 06:47:45 PDT

This also sometimes happens for videos on developer.apple.com, e.g. https://developer.apple.com/videos/play/wwdc2021/10033/. But unfortunately I still don't have a reproducer.

If we don't have time to investigate this soon, maybe a hack would work where we pause every video, then restart video playback? I know that sounds awful, but it would be a lot better than playing videos without sound.

FTR I can't reproduce it anymore in either stable or canary.

I think it was a pipewire issue really.

For the record, what's your OS and pipewire versions?

I hit this several times per day with Ephy Tech Preview on Fedora 34 with pipewire 0.3.33-3.fc34. It's not fixed.

Anything we can do to help with this?

I think it's a pipewire bug, filed: https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/1738

Comment 11 Michael Catanzaro 2021-12-05 08:24:35 PST

With 2.35.1, I notice there is a roughly 50% chance that the video will become either muted or unmuted after performing a seek. I have to keep seeking sometimes several times in a row in order to get the sound to play again.

This is closed ^ ^, so can we close this too?

Comment 13 Michael Catanzaro 2022-02-13 07:52:45 PST

Yes, it's been a few weeks since I last saw this bug, so I'm fairly confident it's fixed.
