My notebook is possibly the most Linux-incompatible machine that's ever been made. Here's a tip: Don't buy an Asus A6R. It's one of the worst notebooks I've ever owned.
Sound didn't work straight off. The notebook has an IXP SB400 AC'97 Audio Controller, according to Ubuntu's Device Manager. If you've got the same sound card, and want to get it working, you need to do two things.
(1) Double-click the speaker icon in Ubuntu's system tray and click Edit -> Preferences in the Volume Control window that appears. In the list, look for the Master Surround entry, and put a checkbox in it. Then look for External Amplifier and put a check in it. Click the Close button then click the Switches tab in the Volume Control window. Remove the check against External Amplifier.
(2) Then click the Playback tab and click the Speaker icon beneath the Master Surround slider, so that it's no longer muted. Then adjust the slider. Playback some audio and you should find everything now works. Basically, the Master Surround slider is now your volume slider. Weird, but true. To make the system tray applet use the Master Surround to control the volume, right-click the system tray speaker icon, select Preferences, and select Master Surround in the list. "
yes you would have to reboot once you blacklisted a module. Or you could remove the module with
$ sudo rmmod snd-atiixp-modem
I would recommend rebooting anyway just to be sure.
Sorry, now in english:
add to /etc/modprobe.d/options the line(s)
# for soundchip snd_atiixp
options snd-atiixp ac97_codec=0
and restart the system. Hope it helps.
