Save. Close. Reboot.
Check your levels in alsamixer.
Press <F6> to select the correct soundcard.
Press <F3> to show playback levels. <F4> selects capture levels [or use <Tab>]
Use the left/right arrow keys to select and up/down arrow keys to change levels. <M> to mute/unmute.
Go to "System ->Preferences ->Sound" and make sure the correct soundcard is default and adjust your profile on the hardware tab.
On the output tab choose the correct device.

Code:
AD1988/AD1988B/AD1989A/AD1989B
