Rattling sound from Linux to Android about audio-share HOT 6 CLOSED

It may be caused by PipeWire itself. Run pw-play -v test.wav to see the delay.

Rocky Linux 9 works well, the delay is 2048 and I can hear a clear sound.

I also test on Fedora 39, which delay is 10240 and I can hear noisy sound.

Maybe changing some config of PipeWire can fix it. But I'm not familiar with it.

I can confirm that with pw-play, I had rattling sound as well. But after following the instructions from https://linuxmusicians.com/viewtopic.php?t=25768, I was able to get clear sound with pw-play. Unfortunately, the remote audio still is noisy even though pw-play is working well.

This post introduce the new config way using pw-metadata -n settings instead of editing the .conf file directly. But the Rokcy Linux 9 and Fedora 39 both have same runtime settings.

The Rocky 9 and Fedora 39 are both installed in my VirtualBox. I install VBox Guest Additions for Fedora 39 and the sound become clear while the PipeWire settings is untouched.

I'll close this issue. If you still have problem, you can reopen it.

Here is a little tip for other Linux users: there is a flatpak app that relays audio from Linux device without rattling sound but perhaps higher latency: https://flathub.org/apps/de.haeckerfelix.AudioSharing
