Hi,
I have a MSI GX720-061 laptop. The sound card is the following:
$ lspci |grep Audio
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio
Controller (rev 03)
$ aplay -l
**** Liste des PLAYBACK périphériques ****
carte 0: Intel [HDA Intel], périphérique 0 : ALC1200 Analog [ALC1200
Analog]
Sous-périphériques: 0/1
Sous-périphérique: #0: subdevice #0
carte 0: Intel [HDA Intel], périphérique 1 : ALC1200 Digital [ALC1200

carte 0: Intel [HDA Intel], périphérique 6 : Si3054 Modem [Si3054 Modem]
Sous-périphériques: 1/1
Sous-périphérique: #0: subdevice #0
Note that in Intrepid it was recognized as ALC888. However my problem
remains in Jaunty.
These are the alsa packages I have (Ubuntu Jaunty):

This is my kernel:
$ uname -a
Linux rigel 2.6.28-11-generic #38-Ubuntu SMP Fri Mar 27 10:01:17 UTC
2009 x86_64 GNU/Linux
My problem is that I can't have both 7.1 sound and headphones working.
If I add this line to /etc/modprobe.d/alsa-base.conf:
options snd-hda-intel model=6stack-dig position_fix=0
I have 7.1 sound. But if I plug my headphones, I have sound on both
headphones and PC speakers. I try to change sound levels in the mixer
but I can't mute the PC speakers only.
I tried the option probe_mask=1 that is recommended for ALC1200, but it
changed anything.
I found a solution by googleing. It suggested to add this instead:
options snd-hda-intel model=targa-2ch-dig
options snd-hda-intel enable_msi=1
In this case I only have headphones when I plug my headphones. However I
don't have 7.1 sound anymore.
Can someone help me to make my headphones work normally with 7.1 sound?
Please feel free to ask me any information you need.
Many thanks,
---
Tom
