I own this usb sound card and is correctly detected by Ubuntu

Bus 002 Device 004: ID 0763:2024 Midiman M-Audio Fast Track MKI
In Sound settings i see all the devices under Input tab but there's no sound coming in. The hardware volumes are all at max. I've been using this sound card without any trouble in Ubuntu for years and this came after 14.04 installation.

I tried alsamixer but when I switch to the external card it says "This sound device does not have any controls".

Any idea what I can do?
