Public bug reported:
Binary package hint: pulseaudio
I have a MSI GX720 laptop, with an integrated Intel HD Audio - Codec
Realtek ACL1200. I have installed Ubuntu10.10 with the latest realtek
drivers, but Alsa does not recognize the 5.1 external speakers connected
through jacks. It offers only stereo options.
cat /proc/asound/card0/codec#* | grep Codec # adds the following
result:
Codec: Realtek ALC1200
Codec: Motorola Si3054
Codec: Nvidia MCP77/78 HDMI
lspci -v | grep -A8 Audio #adds the following feedback:
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio
Controller (rev 03)
Subsystem: Micro-Star International Co., Ltd. Device 7220
Flags: bus master, fast devsel, latency 0, IRQ 47
Memory at f8ef8000 (64-bit, non-prefetchable) [size=16K]

Kernel modules: snd-hda-intel
00:1c.0 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 1
(rev 03) (prog-if 00 [Normal decode])
in the /etc/pulse/daemon.conf, I have changed the following lines:
default-sample-channels = 6
default-channel-map =
front-left,front-right,rear-left,rear-right,front-center,lfe
Also I added to the alsa-base.conf the following line:
options snd-hda-intel model=targa-6ch-dig
The Pulseaudio has the following version installed:
pulseaudio:
