[solved] pipewire audio issues

I'm trying to get pipewire working but I can't get any audio i/o. The issues i have seem to be very similar to threads like, #282119, but the solutions in the post don't help. To start, when using 'alsamixer' it starts to a blank sound device with no controls, labeled "Card: PipeWire Chip Pipewire" but switching sound cards using f6 to 'Generic' displays all the correct controls and labels the card as "HD-Audio Generic Chip: Realtek ALCS1200A." So even though alsa detects the card "pactl list cards" outputs nothing, and list short sinks shows

[yawnbo@yawnbo ~]$ pactl list short sinks
32	auto_null	PipeWire	float32le 2ch 48000Hz	SUSPENDED

 [yawnbo@yawnbo ~]$ ps -ef | grep pipewire
yawnbo       733     723  0 07:59 ?        00:00:00 /usr/bin/pipewire
yawnbo       734     723  0 07:59 ?        00:00:00 /usr/bin/pipewire-pulse
yawnbo      1929    1269  0 08:31 pts/1    00:00:00 grep --color=auto pipewire 

This output is weird as it shows hdmi audio too, even though its been blacklisted in modprobe.d,

[yawnbo@yawnbo ~]$ lspci -vnn | grep -i audio
2b:00.1 Audio device [0403]: NVIDIA Corporation GP102 HDMI Audio Controller [10de:10ef] (rev a1)
2d:00.4 Audio device [0403]: Advanced Micro Devices, Inc. [AMD] Starship/Matisse HD Audio Controller [1022:1487]

On the previous point, snd_hda_codec_hdmi was blacklisted from modules using 'blacklist snd_hda_codec_hdmi' which didn't work, so i switched to,

[yawnbo@yawnbo ~]$ cat /etc/modprobe.d/blacklist.conf
install snd_hda_codec_hdmi /bin/true

I am 100% sure this is my fault in config as this,

[yawnbo@yawnbo ~]$ speaker-test -Dhw:1,0 -c2

speaker-test 1.2.11

Playback device is hw:1,0
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 64 to 1048576
Period size range from 32 to 524288
Periods = 4
was set period_size = 12000
was set buffer_size = 48000
 0 - Front Left
 1 - Front Right

Plays a static sound confirming that the sound is at least somewhere. I assume it's something with pipewire and the hdmi output but I've looked around and can't find anything that helped.
Other relevant output,

 [yawnbo@yawnbo ~]$ pw-cli ls Node
	id 28, type PipeWire:Interface:Node/3
 		object.serial = "28"
 		factory.id = "10"
 		priority.driver = "20000"
 		node.name = "Dummy-Driver"
	id 29, type PipeWire:Interface:Node/3
 		object.serial = "29"
 		factory.id = "10"
 		priority.driver = "19000"
 		node.name = "Freewheel-Driver"
	id 32, type PipeWire:Interface:Node/3
 		object.serial = "32"
 		factory.id = "18"
 		client.id = "31"
 		node.description = "Dummy Output"
 		node.name = "auto_null"
 		media.class = "Audio/Sink"

[yawnbo@yawnbo ~]$ aplay -l

Any help would be appreciated!

Re: [solved] pipewire audio issues

Post

pactl list cards
pactl list sinks
pactl list sink-inputs

during active playback. is alsa-card-profiles installed? you'd have to do some gymnastics for that not to be the case. But could be that that card doesn't have a correct profile... maybe throw in

journalctl -b --user-unit=pipewire --user-unit=pipewire-pulse --user-unit=wireplumber

Re: [solved] pipewire audio issues

Thanks for the reply!
While sound test is running output of given cmds looks exactly the same as when not i believe

 [yawnbo@yawnbo ~]$ pactl list cards
[yawnbo@yawnbo ~]$ pactl list sinks

[yawnbo@yawnbo ~]$ pactl list sink-inputs

Reinstalled alsa profile pkg and Journalctl shows the following

 [yawnbo@yawnbo ~]$ journalctl -b --user-unit=pipewire --user-unit=pipewire-pulse --user-unit=wireplumber

Edit: looked into why wireplumber decided not to start and realized it was masked.... unmasking fixed everything ffs
