[SOVLED] No sound with PulseAudio + ALSA

Hello there

As the title says, I've got a PulseAudio + ALSA setup and was playing sound fine yesterday, but starting up the PC today, I get no sound at all, even after updating PulseAudio to the latest. Anyone know why this is happening?

Presumably your default device changed, go into pavucontrol and make sure the card you want to use is set as the fallback in the output tab and any open applications play to that.

If that wasn't it we need way more information namely

aplay -l
pacmd list-cards
pacmd list-sinks
sudo fuser -v /dev/snd/*

Post the output of these in code tags

Thanks V1del, setting  my default device as fallback fixed it. Still, I'm curious as to why it would suddenly decide not to change it's behaviour so suddenly. Any ideas?

The ALSA update has changed a few things, and if you've never explicitly set your device as the fallback, it's relatively random/dependent on ALSA's card initialization order (which is random unless configured).
