External USB-Soundcard: No Sound!

[Dysport]

Hi everyone!
I'd be really really happy if someone could help me with my problem.
I'm not getting any sound through the external soundcard (internal speaker works fine).
Here are various ouputs from the terminal:

$ lsusb
…
Bus 004 Device 007: ID 0d8c:0102 C-Media Electronics, Inc. CM106 Like Sound Device
…

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC260 Analog [ALC260 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: default [USB Sound Device        ], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

$ cat /proc/asound/modules
 0 snd_hda_intel
 1 snd_usb_audio

The Pulse Audio Applet shows an output when I play music in rhythmbox, but I don't hear a thing (see attached screenshot).

I'm using the computer as a media center in the living room, that's why the sound is really important for me to work!

Hi,

did you selected the external sound card as standard output device?
I also use an external usb sound device and I had the same problem some time ago.
First I looked for my card name:

asoundconf list

then I selected the external card and after restarting the player everything worked fine:

asoundconf set-default-card name

Alternatively you can use asoundconf-gtk package.

As you may see on the screenshot of asoundconf-gtk in my first post, I did set it as standard output and the computer seems to recognize the hardware. That's why I don't know where the problem is (might it be the chipset/vendor of my soundcard? 0d8c:0102)

But thanks for your help anyway!

Sorry,
i was a bit cursorily.

If the card is listed here: http://www.alsa-project.org/main/index.php/Matrix:Main and there is no Note like [Unsupported],
it should be possible to get some sound out of it and the problem is not the chipset/vendor otherwise you'll hardly be able to get it working.

Thanks a lot for the link. Okay, according to this page the chipset should be supported by ALSA - which is probably why im seeing some output on the screen (but have yet to hear something)

[d_liebscher]

Hm,

there are a lot of possibilities for that...

I noticed right yet, that your are from Switzerland. Probably this page may help you:

particularly the part about symptoms

According to the guide on ubuntuusers.de I should check my alsamixer, because it seems to play correctly:

$ aplay /usr/share/sounds/alsa/Front_Center.wav
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

But everything seems to be set correctly there (screenshot attached)
Any more ideas?

(I also attached the .inf from the windoze driver, might contain relevant information?)

[d_liebscher]

Hi,

Alsa Mixer configuration seems to be correct.
No Idea right now, sorry. I have to go for working now, but I will think about it.

[Dysport]

bump…

no one else got an idea?

[d_liebscher]

Hi,

it's me again

i stumble up on an article about the relative new Soundserver Pulse Audio.
Maybe the problem is a conflict between ALSA and PulseeAudio?

I have a lot of work at moment and couldn't read the whole article but maybe you find an advice for a solution.
