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
