1) Description: Ubuntu 15.04
Release: 15.04
3) Since my internal sound card is not working any longer, I am using a Storite
external USB soundcard. It was working perfectly well with Windows, but is
giving me problems in Ubuntu 15.04.
4) The USB device is shown in lsusb but the same is not available in sound
preferences. I am unable to get sound output into my headphone.
