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)
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
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.
