 Posted: Sun May 28, 2023 5:27 am Post subject: No sound after installing pipewire |
 |
|
Edit: forgive the long post. Included all details I thought would be relevant for troubleshooting, and it turned into a monster. TLDR - how can I get sound from my system w/ pipewire?
I run Gentoo on an Intel Tiger Lake NUC as an HTPC using Kodi. I have it configured with alsa (no pulseaudio), and basic audio functionality works fine. Sound plays through HDMI to my A/V receiver. However, I have issues with high resolution sound and passthrough audio, so I'm trying to switch to pipeware w/ the Kodi 21 alpha.
After installing pipeware, I'm not able to get any sound at all, even taking kodi out of it and using aplay. If I uninstall pipewire/wireplumber and change nothing else (aside from rebooting), sounds works again. Reinstall pipewire/wireplumber and reboot, no sound.
I've followed the gentoo wiki and did quite a bit of additional searching and haven't had any luck figuring out why I'm getting this behavior. Would appreciate any assistance.
Here are my pipewire/wireplumber use flags:
| Code: | [ebuild R ] media-video/pipewire-0.3.70-r2:0/0.4::gentoo USE="X bluetooth dbus extra ffmpeg gstreamer pipewire-alsa readline sound-server ssl v4l -doc -echo-cancel -flatpak -gsettings -jack-client -jack-sdk -lv2 -modemmanager (-system-service) -systemd -test -zeroconf" ABI_X86="(64) -32 (-x32)" 0 KiB

Here's some basic device info:
| Code: | $ cat /proc/asound/cards

This is the device that works for HDMI playback:
| Code: | | aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav |
As noted, that works when pipewire is not installed, but fails when pipewire is installed. It doesn't give an error, just silence during playback (pw-play also produces no error, just silcence). AVR reports no signal at all. The only difference in all the output above between working (no pipewire) and not working (w/ pipewire) is the pipewire device at the top of the aplay -L output.
Here's the pipewire status via wireplumber:
| Code: | $ wpctl status
PipeWire 'pipewire-0' [0.3.70, media@screendog, cookie:2022950712]

I set my default audio sink to the HDMI output and set the volume to 95%. I checked the device volume via alsamixer (not sure if that's still needed) and verified the device is unmuted and both master and pcm volume are set to 100%).
I use lxqt w/ SDDM and saw notes that autostart may not work. I verified pipewire, wireplumber, xdg-desktop-portal, elogind, and dbus are all running:
| Code: | $ ps ax | grep -i 'wire\|elogind\|xdg-desktop\|dbus'
1199 ? Ss 0:00 /usr/bin/dbus-daemon --system

If I kill and restart gentoo-pipewire-launcher, the only obvious errors I see are related to rtkit and libcamera. I can't see libcamera really being an issue here, and I'm honestly not sure if rtkit is an issue - I see several posts that say it can be ignored.

I'm out of my depth at this point. Any help would be most appreciated. Thanks.

i'm not sure that it can; the PipeWire page on the wiki says:
| Quote: | | It's recommended that users are in the pipewire group. If the user doesn't have the necessary permissions for this, the configuration will try to use RTKit instead, so the sys-auth/rtkit package may need to be installed. |
and from memory, i indeed needed to install rtkit to get PipeWire working. Is it installed on your system? |

I have xfce4 and HDMI audio and this doesn't work out of the box. Grab a terminal and run 'gentoo-pipewire-launcher &' and pavucontrol is back to let me set HDMI sound.
Then I decided to swap the daemon flag back to pulseaudio because this isn't worth the hassle. Sorry to step over the thread since I've found it easier to withdraw. |
