PulseAudio doesn't detect devices

Dmcinkeit · 2018-04-11 04:45:03

I been trying to get sound to work for a while now. I have alsa mixer and pulse audio and pavucontrol. When I open alsamixer it has all the sound cards that I want but when I open pavucontrol the only thing under output Devices is Dummy Output.
Earlier today it had all the devices in pacucontrol I never actually tested to see if sound was coming through though. Then after a reboot only the Dummy Output was showing up.

If pulse only shows you a dummy output, this usually means that something is already accessing and blocking access to the sound card, which is why pulse is unable to enumerate it. Use

sudo fuser -v /dev/snd/*

to find out what that is.

"sudo fuser -v /dev/snd/*" returned nothing.
Also I accedentally reported your reply my screen was cut off and I saw re and assumed the button was reply.

sudo fuser -v /dev/snd/*
                       USER               PID   ACCESS   COMMAND
/dev/snd/controlC0:    username          3939   F . . . .    pulseaudio
/dev/snd/controlC1:    username          3939   F . . . .    pulseaudio
/dev/snd/controlC2:    username          3939   F . . . .    pulseaudio

except with username replaced with my actual username

Hmm, can you post

aplay -lL
amixer -c0
systemctl --user status pulseaudio

Is this a tablet/netbook/chromebook with a SOC card? Any /etc/asound.conf or .asoundrc or similar?

I had a similar issue today, after I ran an update and rebooted, though the only devices listed was HD Audio (onboard). lspci and lsusb both showed the devices. I ended up downgrading to alsa-*-1.1.5-1 and after a reboot everything worked.

I know downgrading isn't the best way, but I needed to get some recording done, and it worked for me.

wanted to share, YMMV
