[SOLVED] [Pipewire] No output device after recent system updates

obap74 · 2022-10-23 10:35:07

I'm using KDE Plasma and Pipewire. plasma-pa applet just shows "No output or input device found". I don't know precisely when the issue started to occur, I'm using Gentoo on a distinct SSD on the same machine and regularly update my Arch install via chroot. I had not booted into my Arch install for about 10 days and noticed the issue only yesterday.

The following commands give me no output:

sudo fuser -v /dev/snd/*
pacmd list-cards
pactl list sink-inputs

My USB DAC is detected when disconnecting/reconnecting it:

❯ sudo dmesg -w

What I tried so far, to no avail

- Booting with linux-lts-5.15.74-1 and linux-lts-headers-5.15.74-1
- Downgrading to linux-5.19.12.arch1-1
- Downgrading pipewire-pulse from 1:0.3.59-2 to 1:0.3.57-1 and 1:0.3.56-1 (with a reboot between each downgrade)

As stated at the beginning of this post, I'm using Gentoo on the same machine and don't have any audio issue.

❯ eix -cI pipewire

[I] media-video/pipewire (0.3.59-r1(0/0.4)@10/15/2022: Multimedia processing graphs

I'm using multiple custom kernels versions and no audio issue with any of them:

❯ eix -cI gentoo-sources

[I] sys-kernel/gentoo-sources (5.10.149(5.10.149)@10/17/2022 5.15.74(5.15.74)@10/15/2022 6.0.3(6.0.3)@10/21/2022): Full sources including the Gentoo patchset for the 6.0 kernel tree

Any suggestion is appreciated, I'm not sure what to try next.

Thanks!

Edit: Eventually found

but unlike other users, downgrading kernel to 5.19.12 didn't solve the issue unfortunately.

That issue should be fixed on 6.0.2

The output you posted of dmesg reads like snd usb audio isn't even attempted to be used which suggests you aren't booting the kernel you think you are booting what's your output of

 pacman -Q linux; uname -a

Solved by accident. I have user config files for both pipewire and wireplumber. I have overwritten both with the default ones:

% cp /usr/share/wireplumber/main.lua.d/50-alsa-config.lua ~/.config/wireplumber/main.lua.d/50-alsa-config.lua
% cp /usr/share/pipewire/pipewire.conf ~/.config/pipewire/pipewire.conf

Then edited them in $XDG_CONFIG_HOME to include my changes. After running

% systemctl --user restart pipewire-pulse.service pipewire-pulse.socket wireplumber.service

for the umpteenth time, my audio devices started.

I don't know what happened. Maybe the issue was because I previously directly copied /usr/share/wireplumber/main.lua.d/50-alsa-config.lua to ~/.config/wireplumber/main.lua.d/50-alsa-config.lua and did my couple of changes here. Maybe the recent updates included some changes that were causing issues, I didn't think about doing a diff beforehand to check.

I'm now following the Arch Wiki recommendation: I removed ~/.config/wireplumber/main.lua.d/50-alsa-config.lua and created ~/.config/wireplumber/main.lua.d/51-disable-suspension.lua with only what I need to change so that it overrides the default configuration.

Thank you @V1del for answering regardless.
