Sorry. The card works fine on Windows and on Linux. What is the difference? Are you claiming that the driver has other options under windows? Another possibility is that the card does have proprietary controls which they refuse to share with the Linux driver people, or that it is such a small manufacturer that the Linux people have never heard of it. I think you need to give far more information before anyone can help you. Who the manufacturer of the card is what the chipset is, What info you can glean from the windoes driver, etc. > > Best, > Sebastian > > 2012/4/2 Bill Unruh <unruh@xxxxxxxxxxxxxx> > >> On Mon, 2 Apr 2012, Sebastian Gil wrote: >> >> i, I have a usb audio card which only label says "USB GUITAR LINK".
