    Lightbulb [Howto] C-Media USB Headphone Set

    This is a howto to make the C-Media USB Headphone Set work in K/Ubuntu 9.04. I used Kubuntu, didn't try it with Ubuntu...

    Image of the device:

    When you plug in the usb device, linux will recognize it, but sound will not work at all, as it is blacklisted by alsa.

    First, open up alsa-base.conf:

    [Kubuntu] sudo kate /etc/modprobe.d/alsa-base.conf
    or:
    [Ubuntu] sudo gedit /etc/modprobe.d/alsa-base.conf

    Find the following line:

    options snd-usb-audio index=-2

    And change it to:
    #options snd-usb-audio index=-2

    Save and reboot your machine. You should have sound now. If not, open the sound mixer and see if something is muted.

    I also had an other problem: Only one program had sound. If I played something in audacious, youtube had no sound etc...

    To solve this you have to uninstall pulseaudio and install esound.

    sudo apt-get remove pulseaudio
    sudo apt-get install esound

    Restart your machine and try again. You may have to set the proper sound device (alsa) for your programs.

    I tested this with audacious, smplayer and flash.

    - Please confirm that this works for you too..
    - Please confirm that this works in Ubuntu 9.04 too...

    Thank you for your solution. It saved me a lot of time and effort.

    I use an Java application to collaborate with my school and the C-Media head set was not working. I was wasting time by installing bunch of other apps and selecting different mixers. I finally searched for a specific UBS C-Media tag and landed on your solution. In no time it worked flawlessly.

    Appreciate you took the time to post your finding. It saved me big time. Thanks again.

    I am using ubuntu 9.10.

    My headset does not match the image you have but the device ID comes up as C-Media. It has GigaWare name on it. I will try to take a picture of it.

    Thank you very much! It works on 9.10 on a Gigawire usb headset. I also had to change the settings in sound preferences input and output to audio adapter analog.
