I've just had to remove my ASUS Xonar Xense sound card due to a heat and power supply problem in order to restore some stability to my system.

When you buy that, you get a Sennheiser PC350 headset with the larger sized headphone jacks (I'm sorry, I'm not too good with the lingo) and I decided that it'd plug in to my UX1 Toneport, so that I could use it for Skype without the need for the soundcard that I'd just removed.

The problem is that it seems to receive no input sound at all, no matter where I plug it in. I can get playback from the headphones port, but the lead that goes into the instrument/line in port doesn't seem to have any signal. (I should have explained, the PC350 headset has two jacks at the bottom, one recording and one playback.)

I was wondering if there is ANYTHING I can do to use the UX1 to capture from the mic on my headset?

Thank you all very much in advance.
