Try with --env=WEBKIT_GST_ENABLE_AUDIO_MIXER=1 ?

(In reply to Philippe Normand from comment #1) > Try with --env=WEBKIT_GST_ENABLE_AUDIO_MIXER=1 ? That works! Is there a reason for it to not be the default? (I'm just a curious user)

Just discovered why, with --env=WEBKIT_GST_ENABLE_AUDIO_MIXER=1 the audio works for a second and then it jitters and stops working so that solves the problem but creates a bigger one.

(I'm just a curious user) Mainly lack of reverse playback support in the gstreamer audiomixer element.

Works fine here, please provide GST_DEBUG="3,webkitaudio*:6,inter*:6" logs. See https://docs.webkit.org/Ports/WebKitGTK%20and%20WPE%20WebKit/Multimedia.html#flatpak-apps

Just attached the log file. It might be hard to reproduce but what i discovered was that it happens only with specific Bluetooth devices. I can reproduce this every time with a Galaxy Buds Pro(1) but couldn't with a Moondrop Spacetravel(chinese TWS) neither with the built-in notebook speakers or a cabled headphone. Switching to the "Handsfree" option on GNOME Settings sound tab makes audio play again but at a horrible quality, changing codecs does nothing (I could only test AAC and SBC).

Sounds like some PipeWire issue.
