 Posted: Sun May 26, 2024 1:26 pm Post subject: Pipewire & Wireplumber again |
 |
|
My setup:
OS: Gentoo 2.15 x86_64
Host: MS-7C02 (1.0)
Kernel: Linux 6.9.2-RT
Uptime: 44 mins
Packages: 2015 (emerge)
Shell: zsh 5.9
Display (HP LP2475w): 1920x1200 @ 60Hz
Bios (UEFI): 3.60 (5.14)
WM: Openbox (X11)
WM Theme: Friendly-Black-mcc
Theme: Adwaita [GTK3]
Icons: gnome [GTK3]
Cursor: Adwaita
Terminal: kitty 0.35.0
Terminal Font: HackNerdFontComplete-Regular (12pt)
CPU: AMD Ryzen 5 3600 (12) @ 3.60 GHz
GPU: NVIDIA GeForce RTX 2060 SUPER [Discrete]
Memory: 1.95 GiB / 31.30 GiB (6%)
An USB-DAC is connected to the system and the speakers are fed from it and there is no further additional audio device.
This is bare "Gentoo with Openbox" system and no fully fledged desktop environment.
The system is started with the help of OpenRC.
Before wirepluber 0.5 everything works fine. After that: The Sound Of Silence (but not by Simon and Garfunkel).
I followed the instructions here:
https://wiki.gentoo.org/wiki/PipeWire
But obviously I did something wrong, because ... Sound of Silence...
I copied the config-file pipewire.conf to /etc/pipewire/. and ~/.config/pipewire/.
gentoo-pipewire-launcher is started via autostart.sh of openbox before anything else and
put into background.
echo $DBUS_SESSION_BUS_ADDRESS is not empty and valid.
I installed helvum and qpwgraph. But there are basically empty: Nodes without ports.
No node reflects the hardware I am using.
I could make this post even longer by flood it with outputs of pw-cli pw-dump and so forth...
...but this would help...I don't know.
I cannot watch videos about this topic fo obvious reasons...
I need some help...obviously... 
Please let me know, which dump of what may help to solve this problem...
Cheers!

relevant news item
Try to migrate your configuration following the instructions
Edit: As far as I'm concerned I also had to remove old config dirs/files:
| Code: | $ rm -r ~/.config/wireplumber/main.lua.d ~/.local/state/wireplumber
# rm -r /etc/pipewire /etc/wireplumber/bluetooth.lua.d /etc/wireplumber/main.lua.d |
Now there's only
| Code: | | /etc/wireplumber/wireplumber.conf.d/gentoo-sound-server-enable-audio-bluetooth.conf |
installed by media-video/pipewire.
After a reboot, sound came back.

I read the news item beforehand - I had no configuration.
The news item said:
+Most typical desktop users, including EasyEffects users, should not
+notice any change to their system. That said, it was not uncommon for
+people to suggest or implement configuration changes using the Lua API.
...so I thougth, I would be one of the "most typical desktop users".
Unfortunately there is nothing I could migrate.
I am missing the nodes reflecting my hardware and I am missing the ports to connect with.
How can I proceed successfully? |

| To be sure you are working on the right problem, have you confirmed that if you halt all Pipewire/Wireplumber processes, and use straight ALSA to play a test file, that the test file produces sounds as expected? If ALSA is broken, Pipewire has no hope of working, so the first step is to verify that ALSA works. Once you know ALSA works, then you can look at why higher level programs are not using it successfully. |

In the meanwhile I found the problem:
The default configuration, which comes with installation of pipewire only defines a audio source.
To play audio one needs a audion sink.
It is easy to acchieve:
Copy this block (the definition of the audio source):
| Code: | { factory = adapter
args = {
factory.name = api.alsa.pcm.source
node.name = "alsa-source"
node.description = "PCM Source"
media.class = "Audio/Source"
api.alsa.path = "hw:0"
api.alsa.period-size = 1024
api.alsa.headroom = 0
api.alsa.disable-mmap = false
api.alsa.disable-batch = false
audio.format = "S16LE"
audio.rate = 48000
audio.channels = 2
audio.position = "FL,FR"
}
}
|
and paste it right below that block - so duplicate is like so - and replace all accourances of "source" with "sink"
(as mentioned in the comment aboive the first block):
| Code: |
{ factory = adapter
args = {
factory.name = api.alsa.pcm.source
node.name = "alsa-source"
node.description = "PCM Source"
media.class = "Audio/Source"
api.alsa.path = "hw:0"
api.alsa.period-size = 1024
api.alsa.headroom = 0
api.alsa.disable-mmap = false
api.alsa.disable-batch = false
audio.format = "S16LE"
audio.rate = 48000
audio.channels = 2
audio.position = "FL,FR"
}
}
{ factory = adapter
args = {
factory.name = api.alsa.pcm.sink
node.name = "alsa-sink"
node.description = "PCM Sink"
media.class = "Audio/Sink"
api.alsa.path = "hw:0"
api.alsa.period-size = 1024
api.alsa.headroom = 0
api.alsa.disable-mmap = false
api.alsa.disable-batch = false
audio.format = "S16LE"
audio.rate = 48000
audio.channels = 2
audio.position = "FL,FR"
}
}
|
Why the default configuration does not include a audio sink is not obvious to me.
Log out of your account, log in again and with
`
you get an Audio source and Audio sink node listed.
That fixes the problem for me.
Cheers!
