Switching Audio Interfaces in Pulseaudio

Sometimes there is a need to switch between soundcards and devices in a running system. For example, you may have a computer which boots with no sound because Skywave Linux automatically selected the wrong device for your actual hardware. Here is a script which will switch do a different configuration and run an audio test to make sure it is correct. Download from the link here:

https://github.com/brightflash64/Skywave-Linux/blob/master/audioswitch.sh

After downloading the script, make it executable by using the chmod command or permissions settings in the file manager. Execute in a terminal with ./audioswitch.sh, then select a card:device combination. If the selection can't work, the script will fail with an error. If it works, you will hear a test tone.

Terminate the script by entering [Ctrl] + C.
