Hello My Name is Peter Oehry and I own a Fast Track Pro USB interface from M-Audio. Maybe you can help me to improve the usb driver to support the 24-Bit capability of this device. What I found out so far: The device has two configuration sets. The first one (chosen by default) supports only 16-Bit. This mode works without any problems. As I switched to the second configuration (by writint 2 to /sys/bus/usb/devices/1-1/bConfigurationValue) more Interface alternatives can be seen. I could mail the complete device description. How can I add a quirk that the Configuration set is chosen by default? In this configuration I was able to connect and get some sound through the 24-Bit mode. But the sound seems to be a little bit scrambled up. One chanel has only a bit of the propper sound with very high distortion and the other channel has almost the right sound. But also higher distortion than in 16-Bit mode. Does any body know this sort of problems? Maybe another device has a similar problem. Maybe one of the existent quirks will do the job? Where can I start to debug the problem?
