Hi,

I'm trying to get an usb sound card (trust sc-5500p) to work.

I bought the sound card to allow line in input for a notebook only having audio out and mic in.

Now everything works except line in :-(

Audio system is pulseaudio, the line in shows up in pavucontrol but if I select it, I do not get any signal. If I connect a microfone and switch input, I can record.
Configuration is set to Analog Stereo Duplex.

Recording is done (for my experiments) using audacity.

The hardware is ok, under windows I get line-in input :-(

The system is running xubuntu 12.04.

I'm not too familiar with linux sound configuration, so maybe I miss something. I tried to google the issue but did not find a solution.

Any help?

best
