hi,

just installed ubuntu 8.04 on a dell inspiron 9100 laptop today and besides fun with the wireless, it's not been going too badly -- save for my sound.

my master audio channel isn't -- that is, nothing i do to the settings on that channel affects the sound, whereas fiddling with the headphone and PCM channels adjusts the sound in varying ways. headphones seems to affect the treble, but i'm not sure. the volume buttons located above my keyboard affect the master control, but as previously stated, the master control doesn't actually affect the sound. ^^;

my list of playback devices is as follows:

card 0: ICH5 [Intel ICH5], device 0: Intel ICH [Intel ICH5]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: ICH5 [Intel ICH5], device 4: Intel ICH - IEC958 [Intel ICH5 - IEC958]
Subdevices: 1/1
Subdevice #0: subdevice #0

help? i'm trying to get this computer set up for my non-native-english-speaking mother before i leave, and it's been like the blind leading the blind. ^_^;
