Back Panel - No Sound, Headphones - Sound
 

hi all,

i'm able to get sound through the headphone jack (with a set of headphones, of course), but i get no sound out of the mobo's back panel sound jack.

os: u6.10 - edgy eft
mobo: asus a8s-x
chipset: SI7012
module: snd-intel8x0
alsa mixer - everything is maxed

i'm at a loss when it comes to troubleshooting this problem.

any guidance would be appreciated.

since ubuntu recognizes my sound card, as evidenced by my headphones playing, what method of troubleshooting can i follow to try and nail down this problem?

is there a setting that will shut off mobo sound, but not headphone sound? i checked the bios and sound is on. i turned everything up in alsamixer, but i still didn't get sound. i'm not sure if the settings were actually saved when i hit escape to leave the alsamixer.

is there a mobo jumper setting that has to do with sound? is there a way to test the mobo for sound? i can hear the internal beeps at start up.

any help or guidance is appreciated.
