These are notes related to using Ubuntu Linux (18.04) as my daily driver on Thinkpad X1.
Dummy Output audio issue
Sometimes when using headphones + mic for video calls, the audio drivers get messed up. This results in no sound and the only driver available is ’Dummy Output’.
This can be resolved by closing all applications which use audio and then running the following command in the terminal:
pulseaudio --kill; sleep 2s; sudo alsa force-reload ; pulseaudio --start
