Audio Card Test | Puolanka Info

A test if there is some problems to select the right audio card.

The safest way to edit /etc/asound.conf file is to use some editor. But if you want to live dangerously, you can use SET_DEFAULT_SOUNDCARD-final.

If you mess your audio, a default asound.conf file is in this package, so you can use it as a backup.

sudo cp asound.conf /etc/asound.conf

Using Mini-Control-Center you can make a speaker test and more other tests.
