support for usb soundcards

[rperre]

ah thank you, because i do like to retain my hdmi sound, which i thought didn't work correct on 1.0.17 if my memory serves me well.

Problem with removing alsa-modules-`uname -r` is that this then means there is no support for my main soundcard! (hda nvidia)

Hi,

you are right - I have the same problem...

Hi,

I did a fresh LinuxMCE install - before I executed the LinuxMCE installation script - I had 3 soundcards - 2 CMedia USB an 1 PCI - so it should be - then I started the LinuxMCE installation script an i only hab one soundcard - the PCI. The USB soundcards are not shown any more.

Regards

Johannes

Similar issues using c-media usb device. Shows in lsusb but not aplay -l or squeezeslave -L.

I have now bought 2 different products, both of which work OTB on my ubuntu 10.04 laptop by launching snd-usb-audio module but FAIL in lmce.

Can anyone shed light on this?
Cheers
Barney

Here is my dmesg on lmce after the device was attached:

Hi Barney,

Here is the output from one of our Dianemo 7.10 systems with a C-Media sound card installed and working under alsa 1.0.22. Something else must be misconfigured on your system;

Hi Andrew,

I agree. I'm out of ideas. Going to try full reinstall with a recent snapshot.

Thanks for your help.
Barney

[b4rney]

For what it's worth ..... just did a full clean install from recent snapshot 23736 and I am seeing the exact same dmesg errors when plugging in either of my two usb soundcards and no device added to alsa.

Hi Barney

Post your dmesg output here please.

All the best

Hi Andrew,

See my post above, the messages are identical on my old and new build:
http://forum.linuxmce.org/index.php?topic=10268.msg79043#msg79043

I also found this similar sounding (alsa/v4l/dmesg/disagrees about version of symbol) ticket raised by bongowongo. Not 100% that they are related though:
http://svn.linuxmce.org/trac.cgi/ticket/756

Thanks for looking at this.
Barney

[b4rney]

I had also version symbol argument in dmesg, I reverted to an earlier version of ALSA
using the following command, see if it is ok in dmesg

Code Select Expand

apt-get remove alsa-modules-`uname -r`
and
reboot

This fixed the usb card for me too! Thanks!
Just need to get squeezeslave to play nice.
