Ubuntu – Change default sound device


After upgrading to Ubuntu 13.10 my sound stopped working. I eventually figured out that Ubuntu had selected the HDMI sound device instead of my analogue speakers. I switched to the correct device and everything worked fine until I rebooted. I now have to select the correct device every time I boot Ubuntu. How do I set my speakers as the default device?

Edit: Since i upgraded to Ubuntu 14.04 Ubuntu now selects the onboard sound device by default so I no longer have this problem.

$ pacmd list-cards

To display the index of your cards. For example, my pci sound card is at index 2. The sound profile for analogue output (again as an example) is called "output:analog-stereo".


$ pacmd set-card-profile 2 output:analog-stereo

To set this as the output (give it a try). To make it permanent, edit /etc/pulse/default.pa and add:

set-card-profile 2  output:analog-stereo
set-default-sink 2

Restart pulseaudio or reboot to check persistence.

If you want to also set mic(input) defaults

set-card-profile 2  output:analog-stereo+input:analog-stereo
set-default-sink 2
