SubjectNo mixers on ATI RS780 Azalia
Hi,


I have here a Samsung 320MXn2 monitor/mainboard (typical x86_64
environment) where I cannot get sound output to the internal speakers
working.

To start, there seem to be two sound cards:

lspci/lspci -n:
00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
01:05.1 Audio device: ATI Technologies Inc RS780 Azalia controller
00:14.2 0403: 1002:4383
01:05.1 0403: 1002:960f

/proc/asound/cards:
0 [SB ]: HDA-Intel - HDA ATI SB
HDA ATI SB at 0xf0500000 irq 16
1 [HDMI]: HDA-Intel - HDA ATI HDMI
HDA ATI HDMI at 0xf0110000 irq 19
The soundcard responsible for the internal speaker is the 01:05.1/"HDMI"
one.
Under Windows XP, I see the following mixer elements for it:

* Master Volume
* Wave
* SW Synth
* CD Player

Subsequently, there is sound (once I bump the volumes on these).

However, in Linux up to including 2.6.34, I only see a single mixer
element:

* IEC958/S/PDIF

mplayer etc. all successfully write to the device, but since there are
not any further mixer controls, I can't unmute the essential channels.

alsa-utils is version 1.0.21, from openSUSE 11.2 x86_64.


Any help is appreciated.

Thanks,
Jan
