USB headset works in Ubuntu but not Fedora

[Iain Cheyne]

I am trying to transition to Fedora 7, and so far it's been easy, but I can't
get my new USB headset's mike working in Skype.

It's a Plantronics .Audio 500 USB.

Both "less /proc/asound/cards" and "less /proc/asound/devices" show that it is
detected fine.

I can get the headphones to work by setting the usb devices in the Skype
settings, but not the mike. I used the same config in Ubuntu Feisty and it
worked perfectly.

Any ideas?
