So does this mean I can compile and install 1.0.22 then just use the custom /etc/asound and the intel hd file?

Yes, exactly. We don't need to patch Alsa anymore. The patch is included. We can now use all sampleformats and frequencies. The custom files only needed because of the wrong channel mapping still in the code.

Thanks. One other question. is Nvidia 195.53 still broke sound wise? I was told that it mutes all channels except front L&R or some such when passing 7.1 LPCM?

Actually I jsut realized there is a 190.53 and a 195.30. Whats the difference?

Troubleshooting help needed Karmic 64bit, XBMC 9.11, Alsa 1.0.22 - hahel - 2009-12-26 15:13

Hi!

I've read the thread and tried to roughly follow the guide on the first page,
I used a modified version of the original Alsa Upgrade script to download and compile ALSA 1.0.22.
This seems to be OK:

Code:

#cat /proc/asound/version

Advanced Linux Sound Architecture Driver Version 1.0.22.

Compiled on Dec 26 2009 for kernel 2.6.31-16-generic (SMP).

#aplay -l

**** List of PLAYBACK Hardware Devices ****

card 0: NVidia [HDA NVidia], device 3: NVIDIA HDMI [NVIDIA HDMI]

  Subdevices: 1/1

  Subdevice #0: subdevice #0

However the commands:

Code:

/usr/bin/amixer -q -c 0 sset 'Master',0 unmute && /usr/bin/amixer -q -c 0 sset 'Master',0 100 

/usr/bin/amixer -q -c 0 sset 'IEC958 Default PCM',0 unmute

/usr/bin/amixer -q -c 0 sset 'IEC958',0 unmute && /usr/bin/amixer -q -c 0 sset 'IEC958',1 unmute

sudo alsactl store

Gives the following results:

Code:

amixer: Unable to find simple control 'Master',0

amixer: Unable to find simple control 'IEC958 Default PCM',0

amixer: Unable to find simple control 'IEC958',1

Running Speakertest -c2/-c6 gives me sound but when running XBMC everything is silent, (video & music).

In my XBMC audio settings dialog there are not the same alternatives as in
http://img27.imageshack.us/i/xbmchdmisetting.jpg//

My AudioOut has a "Internal Audio Digital Stereo (HDMI)" device
My Passthrough device is labeled "hdmi".

HW: M3N78-EM (Geforce 8300) AMD X2 4450
Nvidia driver : 185.18.36

Any suggestions on where i should go from here?

this is on alsa 1.0.22 (same error here, but audio work)
check alsamixer manually

Alsamixer only shows a S/PDIF output channel.
