Hello everybody,
I crashed up my audio configuration on my RPi 4 with LE 10.0.2 (I tried to get dual audio via HDMI and USB simultanously, but failed). I have already reverted all configurations for dual audio.
But however, PulseAudio stopped working:

Code
# pacmd list-cards
No PulseAudio daemon running, or not running as session daemon.But ALSA detects all the devices and can use them:
Code
# aplay -L
null
Discard all samples (playback) or generate zero samples (capture)

HDMI Audio OutputWhich configuration setting am I missing to get PA working again?
Thanks!
), basically using the USB/DAC for music and net radio. I had issues too with pulse audio, quality, sometimes works, sometimes not, struggled a lot to make to work stable. Now I'm using the "Audio Profiles" addon, what able to switch the audio output for different media format. If you don't need to have simultaneous audio (another challenge to synchronize the HDMI and the USB delay...), only different output for different type of media, try it. More info here:
