Hi Raymond,
About my problem, the audio card with the latest patches seems to work
(but
great noise when nothing is playing is present, i also tried to mute everything in alsamixer) so i could say "it works with model=auto"
I think it just partially works with model=auto
This mean that i must wait that some one fix my sound card? I'm not able to do this by myself
according to your alsa-info.sh
I applied the patch, and build the kernel, this is my lastest alsa-info:
http://www.alsa-project.org/db/?f=61aa4129d0ea771ebc7226ea80c5c3ead24ef05c
There are two sets of capture volume/switch and input sources controls but only one capture device
So the patch is not working for my hw, or I was wrong with configuration?
ARECORD
**** List of CAPTURE Hardware Devices **** card 0: Intel [HDA Intel], device 0: ALC892 Analog [ALC892 Analog] Subdevices: 1/1
Simple mixer control 'Input Source',0 Capabilities: cenum Items: 'Rear Mic' 'Front Mic' 'Line' Item0: 'Rear Mic' Simple mixer control 'Input Source',1 Capabilities: cenum Items: 'Rear Mic' 'Front Mic' 'Line' Item0: 'Line'
What kind of noise ?
Do you mean that the noise can be hear in HP and all audio jacks at rear panel ?
Have you try those parameter in
http://git.alsa-project.org/?p=alsa-kernel.git;a=blob_plain;f=Documentation/...
Assuming that you are using default devices in /usr/share/alsa/cards/HDA-Intel.conf
You should keep "PCM Playback Volume" at 0dB since it a softvol plugin
Simple mixer control 'PCM',0 Capabilities: pvolume penum Playback channels: Front Left - Front Right Limits: Playback 0 - 255 Mono: Front Left: Playback 180 [71%] [-15.00dB] Front Right: Playback 180 [71%] [-15.00dB]

So i made the test, i correctly hear the tests, 7 outputs for the rear panel, and 2 for the front, but when i play the first test, i hear on the front panel some noise and realy crackly and whispered the tests when front left and front right are played, i guess it is not normal, may this help?
Can you compile the driver --with-debug=verbose ?
I'm building the kernel version of the alsa driver, using the kernel git from takashi, how could I pass the verbose parameter while building the kernel version of the driver, somethings in the sound/Makefile or i should enable the "Verbose printk" ?
Check those hda_codec_setup_stream , hda_codec_prepare_stream and hda_codec_cleanup_stream
when the driver is init, "independent HP" is off by default so you should find one setup stream/cleanup stream for each DAC
when turn on , only four DAC is used when playing 8 channels
only 1 DAC is used for device 2 _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
What about the rear / front problem that make hear only one channel at front and only one channel at rear is a configuration problem or a driver problem? I tried a lot deleting asound.state Help me to collect the informations that you need, sorry for my noobish.
