Problem with Alsa and Headset

[althena77]

Hello!!

I got a Logitech USB 20 Headset for Skype. It is working fine under Gentoox, but only when I update Alsa via "emerge alsa". Seems that te module snd-usb-audio is needed, which is missing with Alsa installed via magic.

However when I emerge Alsa, loading the module snd-intel8x0 fails at startup and I have no sound from the TV speakers anymore.

Is there an way to get both working??

checkout xbox-linux CVS, shallax brought some stuff "back from the cemetery" this shows you how to manually emerge alsa to work with the xbox

Thank you very much for your reply

I downloaded the Alsa sources and the Alsa patch for Xbox and did everything exactly like said in the readme:

Step 1: First catch your ALSA
$ wget ftp://ftp.alsa-project.org/pub/driver/a ... .8.tar.bz2

Step 2: Untar
$ tar -jxvf alsa-driver-1.0.8.tar.bz2

Step 3: Patch the sources with the .patch file included.
$ cd alsa-driver-1.0.8; patch -p1 < ../alsa-driver-1.0.8.xbox.patch

Step 4: Configure ALSA suitably
$ ./configure --with-cards=intel8x0

Step 5: Build alsa.
$ make && make install && rmmod snd-intel8x0 xbox=1 && modprobe snd-intel8x0 && modprobe snd-pcm-oss

It worked, but it seems that this does the same as when I install Alsa via magic. Now I can load the module snd-intel8x0 again and have sound from the TV speakers but the module snd-usb-audio is missing again and I can't use my headset
Why is the module snd-usb-audio missing when I install Alsa with the patch?? No matter how I install it, it is always the same version 1.0.8??
