Hey gang,

Yup, yet another user issue with only getting "Dummy output" when using pipewire + pulse

Here's a bunch of info:

emerge --info

equery u pipewire
Code:

[ Legend : U - final flag setting for installation]
[        : I - package is installed with flag     ]
[ Colors : set, unset                             ]
 * Found these USE flags for media-video/pipewire-9999:
 U I
 + + X             : Enable audible bell for X11
 + + abi_x86_32    : 32-bit (x86) libraries
 + + bluetooth     : Enable Bluetooth Support
 + + dbus          : Enable dbus support for anything that needs it (gpsd, gnomemeeting, etc)
 - - doc           : Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
 - - echo-cancel   : Enable WebRTC-based echo canceller via media-libs/webrtc-audio-processing

 + + gstreamer     : Add support for media-libs/gstreamer (Streaming media)
 - - ieee1394      : Enable FireWire/iLink IEEE1394 support (dv, camera, ...)
 - - jack-client   : Install a plugin for running PipeWire as a JACK client
 - - jack-sdk      : Use PipeWire as JACK replacement
 - - liblc3        : Allow loading LC3 plugins via media-sound/liblc3
 - - lv2           : Allow loading LV2 plugins via media-libs/lv2
 + + man           : Build and install man pages
 - - modemmanager  : Combined with USE=bluetooth, allows PipeWire to perform telephony on mobile devices.
 - - pipewire-alsa : Replace PulseAudio's ALSA plugin with PipeWire's plugin
 + + readline      : Enable support for libreadline, a GNU line-editing library that almost everyone wants
 - - roc           : Enable roc support for real-time audio streaming over the network, using media-libs/roc-toolkit. See https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Network#roc
 + + sound-server  : Provide sound server using ALSA and bluetooth devices
 + + ssl           : Enable raop-sink support (needs dev-libs/openssl)
 - - systemd       : Enable use of systemd-specific libraries and features like socket activation or session tracking
 - - test          : Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)

Try enabling the pipewire-alsa USE flag.

Also, it may be pipewire/pulseaudio conflicting not sure.

Hello, I'm new user here. I'm also running into this issue.
I tried enabling pipewire-alsa USE flag but it didn't work.

I don't believe I have anything with pulseaudio running. The following you'll see that all the pulse related things are commented out in my /usr/share/pipewire/ directory:
Code:

# rg 'pulse' /usr/share/pipewire/*
/usr/share/pipewire/pipewire.conf
337:    # You can optionally start the pulseaudio-server here as well
342:    #{ path = "/usr/bin/pipewire" args = [ "-c" "pipewire-pulse.conf" ]
343:    #  condition = [ { exec.pipewire-pulse = null } { exec.pipewire-pulse = true } ] }

/usr/share/pipewire/pipewire-avb.conf
1:# PulseAudio config file for PipeWire version "1.1.0" #
7:# /etc/pipewire/pipewire-pulse.conf.d/ for system-wide changes or in
8:# ~/.config/pipewire/pipewire-pulse.conf.d/ for local changes.

/usr/share/pipewire/minimal.conf
48:    # Load the pulseaudio emulation daemon
49:    minimal.use-pulse = true
153:    { name = libpipewire-module-protocol-pulse
154:      condition = [ { minimal.use-pulse = true } ]
158:pulse.properties = {
435:    # You can optionally start the pulseaudio-server here as well
440:    ##{ path = "/usr/bin/pipewire" args = "-c pipewire-pulse.conf" }

/usr/share/pipewire/pipewire-pulse.conf
1:# PulseAudio config file for PipeWire version "1.1.0" #
7:# /etc/pipewire/pipewire-pulse.conf.d/ for system-wide changes or in
8:# ~/.config/pipewire/pipewire-pulse.conf.d/ for local changes.
43:    { name = libpipewire-module-protocol-pulse
45:         # contents of pulse.properties can also be placed here
52:# a script or in pulse.cmd below
63:pulse.cmd = [
88:pulse.properties = {
103:    #server.dbus-name       = "org.pulseaudio.Server"
104:    #pulse.min.req          = 128/48000     # 2.7ms
105:    #pulse.default.req      = 960/48000     # 20 milliseconds
106:    #pulse.min.frag         = 128/48000     # 2.7ms
107:    #pulse.default.frag     = 96000/48000   # 2 seconds
108:    #pulse.default.tlength  = 96000/48000   # 2 seconds
109:    #pulse.min.quantum      = 128/48000     # 2.7ms
110:    #pulse.idle.timeout     = 0             # don't pause after underruns
111:    #pulse.default.format   = F32
112:    #pulse.default.position = [ FL FR ]
115:pulse.properties.rules = [
120:                pulse.min.quantum = 1024/48000      # 22ms
127:pulse.rules = [
169:                pulse.min.req          = 512/48000      # 10.6ms
170:                pulse.min.quantum      = 512/48000      # 10.6ms
171:                pulse.idle.timeout     = 5              # pause after 5 seconds of underrun


So I'm not 100% sure. I'll look around for some more stuff here in a bit.

The problem is getting my system to output sound there.

Running speaker-test -t wav -c2 -Dplughw:0,10 and speaker-test -t wav -Dhdmi:CARD=HDMI,DEV=4 is how I figured it out.

Thing is, I have 0 clue how the hell I'm supposed to tell pipewire to output to hdmi:CARD=HDMI,DEV=4 or plughw:0,10. That's all I want to do, and I really don't feel like having to delve into Pipewire's god awful JSON-esque DSL where I have to create a new node or whatever.

This is in my ~/.asoundrc

Code:

# pcm.!default {
#     type hw
#     card Audio
# }

# ctl.!default {
#     type hw
#     card Audio
# }

defaults.pcm.card 0
# defaults.pcm.device 10
defaults.ctl.card 0
defaults.pcm.dmix.rate 48000


I really have no idea what to do now.

Move away your ~/.asoundrc and also /etc/asound.conf if that exists, then restart pipewire/wireplumber and see if that helps.
