Logitech USB headset not working on 12.04

Solution 1:

Finally the headset is usable now. I just did an update recently, also additionally I've updated from the ppa:ubuntu-audio-dev/ppa

sudo add-apt-repository ppa:ubuntu-audio-dev/ppa

sudo apt-get update; sudo apt-get dist-upgrade -y

Now the usb headset is on the input and output tabs.

Solution 2:

I opened system settings->sound. In that open Hardware tab. It shows logitech USB headset. Now click on Test Speakers, Front left, right. After this I able to get the audio from the headset.

Solution 3:

This may not be your problem, but I had similar trouble with a plantronics usb headset and found my solution here.
