[SOLVED] PipeWire: no audio hardware found, "no node available"

replax · 2020-12-27 13:31:06

Hello,

just for fun, I did a fresh arch install and wanted to test out pipewire (only) for audio.

However, no audio hardware devices are being recognised.
My hardware devices are an USB DAC and notebook speakers (thinkpad t480s).

I installed

pacman -S pipewire pipewire-pulse pipewire-alsa pavucontrol alsa-utils mpv
systemctl --user enable pipewire.socket pipewire-pulse.socket
systemctl --user enable pipewire.service pipewire-pulse.service
### REBOOT ###

Now, there is no sound. When I remove `pipewire-alsa`, I can listen to sound through my USB DAC (alsa, can adjust volume with `alsamixer`). With it installed, `pavucontrol` shows _No output devices available_.
Also whenever I run a program which would like to use a sound output, such as `mpv`, I get the error

[E][000004399.058880][stream.c:295 stream_set_state()] stream 0x55ef5a4723c0: error no node available

Did I forget to add myself to a certain user group or am I overseeing something very obvious here?
Thanks!

Further debug output:

Can you try restarting pipewire? That may be a race condition during login:

systemctl --user restart ...

https://gitlab.freedesktop.org/pipewire … issues/439
https://gitlab.freedesktop.org/pipewire … issues/423

And pipewire does not have a dummy sink like pulseaudio: https://gitlab.freedesktop.org/pipewire … issues/430

Yeah, a

systemctl --user restart pipewire.service pipewire-pulse.service

did not change anything unfortunately. Neither does adding myself to the

audio

group..

Also tried to use pipewire-git but that did not help either, although [this](https://gitlab.freedesktop.org/pipewire … issues/423) should be fixed there..

Any idea on how I could debug further?

Ok, I am a bit stupid...

it does work now. Issue 423 was the deciding one, so I ofc also had to install

pipewire-alsa-git
pipewire-pulse-git
pipewire-git

for that to be fixed.

Interestingly enough, the following error remains on boot:

[ab@archtp480s ~]$ systemctl --user status pipewire.service

but doesn't affect the system. I can now see and switch in/outputs in pavucontrol.
