解决pulseaudio没有输出设备

https://askubuntu.com/questions/976375/kubuntu-17-10-no-audio-devices-found-no-settings-no-sound

I had the exact same problem (same symptoms) and ended up wasting hours looking for a solution. I solved the issue by editing default.pa to statically load modules and replaced hw:1,0 with hw:0,0
sudo nano /etc/pulse/default.pa
Content to change:
load-module module-alsa-sink device=hw:0,0  
load-module module-alsa-source device=hw:0,0  
load-module module-null-sink  
load-module module-pipe-sink  
Save and exit, then run:
sudo alsa force-reload  
pulseaudio -k  
start-pulseaudio-x11  
Hopefully you have sound at this point.
