Hi,
I have no sound. My sound onboard card is a SI7012 (with a Realtek ALC650 sound chip); I wonder if it is correctly detected at boot ? Its PCI ID is 1039:7012:1043:8095.
Here is lspci -vnn output:
Code:
0:02.7 Multimedia audio controller [0401]: Silicon Integrated Systems [SiS] AC'97 Sound Controller [1039:7012] (rev a0)
Subsystem: ASUSTeK Computer Inc. Device [1043:8095]
Flags: bus master, medium devsel, latency 32, IRQ 18
I/O ports at 9400 [size=256]
I/O ports at 9000 [size=128]
Capabilities: <access denied>
Kernel driver in use: Intel ICH
Kernel modules: snd-intel8x0
In the audio settings panel (service menu), I selected ALSA/analog. But something perhaps goes wrong there, as the driver
snd-intel8x0 loads at boot; is an Intel driver the right one for a SIS962 southbridge and a SI7012 / ALC650 sound card ? I am lost.
Nevertheless, sound devices are created:
Code:
ls -l snd sound

ALSA being the active sound system, many drivers related to OSS are still loading. Is it fine ?

lsmod | grep

Switching to OSS drivers through service menu does not give me more sound on the output plug. Of course it makes loading a different driver:
Code:
00:02.7 Multimedia audio controller [0401]: Silicon Integrated Systems [SiS] AC'97 Sound Controller [1039:7012] (rev a0)
Subsystem: ASUSTeK Computer Inc. Device [1043:8095]

I/O ports at 9400 [size=256]
I/O ports at 9000 [size=128]
Capabilities: <access denied>
Kernel driver in use: oss_ich
A sound device is then created:
Code:
lrwxrwxrwx 1 root root 22 2010-05-26 16:03 dsp -> /dev/oss/oss_ich0/pcm0
lrwxrwxrwx 1 root root 22 2010-05-26 16:03 dsp0 -> /dev/oss/oss_ich0/pcm0
lrwxrwxrwx 1 root root 22 2010-05-26 16:03 dsp_ac3 -> /dev/oss/oss_ich0/pcm0
lrwxrwxrwx 1 root root 22 2010-05-26 16:03 dsp_in -> /dev/oss/oss_ich0/pcm0
lrwxrwxrwx 1 root root 22 2010-05-26 16:03 dsp_mmap -> /dev/oss/oss_ich0/pcm0
lrwxrwxrwx 1 root root 22 2010-05-26 16:03 dsp_multich -> /dev/oss/oss_ich0/pcm0
lrwxrwxrwx 1 root root 22 2010-05-26 16:03 dsp_out -> /dev/oss/oss_ich0/pcm0
Is there something wrong there, something I can fix ? Have I just to open a bug report and wait for a possible solution with a next upgrade ? This is quite annoying to run a mythbox with a dead sound output.
My onboard sound chip shares the same IRQ as my DVB capture card. Might it be a reason for an hardware conflict ? (see
Satelco EasyWatch PCI DVB-S 1131:7146:1894:001b)
Support on both issues is warmly welcomed.
