C-Media cm106: No master volume

[Stig Færch]

MythBuntu 9.10

I have got myself a cm106 (or cm6206?) based external usb soundcard, because I gave up on getting the internal soundcard working:
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/494879

Anyway. With my new external soundcard, sound is finally working. Unfortunately it doesn't seem like I have any Master Volume. Under playback in the alsamixer I have: Microphone, Speaker(2ch), Speaker1(8ch).
(The Gnome Alsa Mixer shows PCM, PCM, Mic, Speaker, Speaker - doesn't seem that I can control the channels individually here. I think PCM, PCM is for recording)

The Speaker with 2channels doesn't seem to control anything (optical out?).
Speaker1 controls the channels just fine.

The problem is that I don't have any Master Volume to control the output volume.

The second problem would be to bind the volume control button on my laptop to my missing master volume (currently it's connected to my internal soundcard) - but that's not a bug.

Please run this command in a terminal: "apport-collect -p alsa-base 513634"

This is to collect information about your sound hardware. Please do this when the USB card is plugged in.

Thanks

Btw. don't know if I should have rebooted before running the apport command.
The PulseAudio Applet mixer didn't respond correctly - but did in the beginning.
Let me know if I should reboot and run it again.

I will try contact the manufacturer to get more information about this sound chip.
What documents should we ask the manufacturer for, to get features implemented and "bugs" in alsa fixed?

Hi Stig,

Please, if you are still having issues, test with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p alsa-base 513634

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds .

Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

Please let us know your results.

Gave up and went back to Windows XP. That's the sad fact.
