I set this up in my local ALSA configuration to make it work probably with the external USB headset:
# $HOME/.asoundrc
pcm.usb-audio {
type plug
slave.pcm "hw:1"
}
ctl.usb-audio {
type hw
card 1
}
pcm.!default {
type hw
card Headset
}
ctl.!default {
type hw
card Headset
}
The name "Headset", I got by looking at the output from:
$ cat /proc/asound/cards
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xfebfc000 irq 21
1 [Headset ]: USB-Audio - Logitech USB Headset
Logitech Logitech USB Headset at
Now, the audio and microphone works both in Skype and other places, like XMMS2.
