view story

http://askubuntu.com – I'm new at linux and it's like my second day of usage. Have met 2 problems yet. One of them is that my USB Plantronics Blackwire C220M headset's mic isn't working. I've pluged it in and the headphones started to work imidiatly but mic haven't beed detected at all. Reboot solved that and the mic appeared in the Input devices. But when i try to sellect it the audio setting menu just crushes. Ubuntu asked 2 times to send a report after that's happening and now the audio setting window just silently closing after i try to sellect the headset's mic. Changing USB port don't help.
