Bug 857588 – >=media-video/wireplumber-0.4.10-r6 does not populate PW with audio

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Cedric Sodhi 2022-07-11 11:03:01 UTC]

The attachments are of WIREPLUMBER_DEBUG=3 wireplumber of the respective versions. Starting with 0.4.10-r6 (also present in 0.4.11), wireplumber does no longer create audio nodes in PW and consequently there is no audio.

As for configuration, this happens without /etc/wireplumber (though the logs are from an invocation where /etc/wireplumber is populated with 2 lines to disable logind and libcamera)

Potentially related to BUG #856745

Please check if you have local USE sound-server set for pipewire package:

Thanks, in this case you should have /etc/wireplumber/main.lua.d/89-gentoo-sound-server-enable-alsa-monitor.lua which would enable alsa nodes; if so this looks like a problem with either pipewire or wireplumber themselves, and not with the change introducing local USE sound-server to pipewire.

[Comment 8 Cedric Sodhi 2022-07-11 18:33:51 UTC]

No, I don't have that file because of INSTALL_MASK=/etc/wireplumber, because otherwise on each update I had to zap through 50-ish files. Might it be possible to place this with the default configuration in /usr with pipewire[sound-server]?

[Comment 9 Cedric Sodhi 2022-07-11 18:52:06 UTC]

Can confirm that it works with the 89-gentoo-sound-server-enable-alsa-monitor.lua . Thank you.

[Comment 10 Cedric Sodhi 2022-07-11 18:55:49 UTC]

My reasoning was that the default ( = /usr/ ) configuration should probably contain that (and same for the bluetooth monitor), because it's expected to work by default, like it used to in previous version (though I'm not aware of the reasons why it stopped working).
