No sound output from Spotify on 18.04
The simplest solution is to install pavucontrol sudo apt install pavucontrol
.
Then you launch it and the gui will let you chosse the output for each application.
Yes, I experienced a similar problem today but not just with Spotify.
In my case, no application was able to play the sound.
Only system sounds were coming.
This occured after I had plugged my laptop to my TV using HDMI cable and then unplugged it.
This is how I solved it.
- Connect your PC back to the Device using HDMI port
- Go to display and mirror the screens
- Go to settings>sound.
- Change the audio output to the HDMI device
- Change the audio output back to the laptop/PC
- Go to display and switch back to your laptop screen
- Unplug the HDMI cable
