Hello,
in the interests of helping to debug the mess that is snd-hda-intel and getting sound working properly on my machine, I'd like to report the following problem:
This machine is a Fujitsu Siemens Celsius M440 desktop -- about 4 years old and running Debian lenny. The sound is onboard Intel HD Audio with a Realtek ALC260 codec.
The mainboard (Fujitsu D2178) has the following jacks:
Rear: (left to right) Pink - MIC - Node 0x12 in hda-analyzer Green - Speaker/Line out(?) - Node 0x0f in hda-analyzer Blue - Line in - Node 0x14 in hda-analyzer
Front: (left to right) Green - Headphone - Node 0x15 in hda-analyzer Pink - MIC - Node 0x13 in hda-analyzer
Internal: (at least, can confirm detail if needed) CD Internal speaker
The current status with kernel 2.6.32.5 is as follows:
1) snd_hda_intel loaded with model=basic (the "slightly less broken" option)
Mixer playback behaviour:
Headphone -> nothing Front -> Front and Rear green jack Line -> Not tested CD -> Not tested Beep -> Beep
Capture behaviour:
I've only tested with a headset connected to the front jacks, with "Capture" set to 100% and "Capture Source" set to "Front Mic". In this mode I seem to get a *very weak* signal from the mic as tested by doing "arecord
./test.wav", then "aplay ./tmp.wav".
2) snd_hda_intel loaded with model=auto (the "completely broken" option)
Mixer playback behaviour:
Headphone -> Internal speaker Front -> Rear green jack Beep -> Beep
Capture: untested
In this mode the front jacks don't seem to work at all.
I'd appreciate any help on debugging this. The ideal configuration which I guess should(?) be possible is separate mixers for Front out, Rear out, Internal speaker, and working capture with both Front and Rear Mic.
Also, can anyone suggest a better tool to test recording than "arecord"? Specifically something that will actually tell me if the level of the sound recorded from the Mic is "sane"?
Also see the attached output from alsa-info.sh for both model=auto and model=basic. I tried a few other models but with no luck.
Thanks,
-mato
