The .asoundrc file
From the ALSA wiki
This file allows you to have more advanced control over your card. Some very useful applications will not work without it. At this point is is still a bit of a black art getting the details correct. Make a file called .asoundrc in your home directory
vi ~/.asoundrc
copy and paste the following into the file then save it.
pcm.cmipci {
type hw
card 0
}
ctl.cmipci {
type hw
card 0
}
For a full explanation of the .asoundrc file please read this [1] page or the example in the alsa-driver package.
