[Solve] PulseAudio can not recognize audio card before login KDE

Solution: Please add your user to audio group
Hi,
I have a problem about PulseAudio.
Linux info

Linux highspeed 5.13.10-arch1-1 #1 SMP PREEMPT Thu, 12 Aug 2021 21:59:14 +0000 x86_64 GNU/Linux

I want to  play music remote without login to KDE GUI. So I start PulseAudio manually by

/usr/bin/pulseaudio --daemonize=no  -vvvv

Then List sink

╰─$ pacmd list-sinks
1 sink(s) available.

		device.description = "Dummy Output"
		device.class = "abstract"
		device.icon_name = "audio-card"

as you see, I can not see my audio device.

not work PulseAudio log: https://gist.github.com/wugh/610df07446 … 5324629b80

aplay -L also can not find audio devices

I also try add 'options snd_hda_intel dmic_detect=0' to ' /etc/modprobe.d/disable-dmic.conf' , but did not work.

here is my lspci result

But if I login in to KDE, the PulseAudio can list the audio device.

Here is some debug log output from PulseAudio, get work pulseaudio log is: https://gist.github.com/wugh/b4ee4ebc58 … 6f6ffb64a7

That log appears to be from a working run, post the complete one from when it's not working. This usually happens if you have "something else" actively using the device by the time you start pulse.

Thanks, I update some log.
