So nowadays when this bug occurs, the fix is to simply mute and then unmute the video using the volume control UI in the video widget. I'm not certain, but I don't think that worked at the time that I reported this bug, or I would have mentioned it here. The current bug seems identical to bug #225857 from last year. I have pipewire 0.3.69-2.fc38.

It's not specific to YT. I used the same workaround yesterday on another website that was playing muted... I think this is some racy pipewire behavior, not sure how to demonstrate it though, but the webkit gst logs show the video is un-muted.

This also happens in apps other than Epiphany. I have to do the same in Spotify (from Flathub) and Spot (the GTK Spotify client from Flathub), for example.

Besides muting and unmuting, changing the volume in the UI controls also work.

Can you still reproduce the issues after replacing pulse with alsa? GST_PLUGIN_FEATURE_RANK=pulsesink:0,alsasink:MAX
