I’m trying to configure an external USB audio device on Opensuse 11.1.
It seems to be recognized but it produces no sound/record

this is the output of lsusb command:
ID 0d8c:0102 C-Media Electronics, Inc. CM106 Like Sound Device

I have made the update of alsa driver:
rpm -qa | grep alsa
alsa-utils-1.0.18-6.4
alsa-plugins-pulse-1.0.18-6.12
alsa-devel-1.0.18-8.7
alsa-tools-1.0.18-1.13
alsa-oss-1.0.17-1.37
alsa-plugins-1.0.18-6.12
alsa-1.0.18-8.7
alsa-firmware-1.0.17-1.42
alsa-driver-kmp-pae-1.0.20.20090721_2.6.27.23_0.1-1.1

Does anyone have got this device working on Opensuse 11.1?

Do you have any sound working?

Is there anything here of help:
USB headphones - openSUSE

I notice you have alsa-driver-kmp-pae installed, but have not updated your user space alsa apps. You may wish to consider trying that, … guidance is here: Alsa-update - openSUSE

Thanks for the tips
Not all features of the device works after the update to alsa 1.0.20.git*.
Only 2 channels works, mixer sliders are missing and no spdif output

Output of dmesg command for the usb insertion:

it seems to have a problem setting rate:
/usb/usbaudio.c:1325: current rate 30464 is different from the runtime rate 96000

If I could place a “man-in-the-middle” usb beetween the device and windows I could monitor packages the windows driver sends to the device to control it. so I could copy it.

Does anyone knows how could I do it?
Thanks

Is there a particular reason why you are using alsa-driver-unstable-kmp-pae as opposed to alsa-driver-kmp-pae ?

#5

I’ve changed it to alsa-driver-kmp-pae, but it still has no support for all features of the device, only 2 channels of audio output, and poor support for mic works.

Device is 5x1 with digital input/output

Is there any missing package I need to install in order to control the device properly?

One of the good things about USB was the non-driver dependent installation, Real plug-in-play devices. Now it seems we will pass the nightmare again.>:)

Is it possible you have what you need installed and have not figured out how to configure it?

Here is a thread I started on surround sound:
Exploring surround sound in Linux - openSUSE Forums

What is your criteria for determining poor mic support. Any chance you have not figured out how to configure it.

Since I can’t see your mixer output nor the settings that you have applied (where the mixer output is part of the alsa-info.sh diagnostic script output) its not possible to give specific advice.

You could run:
/usr/sbin/alsa-info.sh
and post here the URL (of the script output) provided from running that
