I've installed the MCN Live Toronto to my hard drive. I'm enjoying it quite well, and I'm trying to use a USB mic. to record audio. I've searched and found a few references which say:

"Heres a patch for sound/usb/usbmixer.c in 2.6.19.1. You may need to use OSS emulation for some applications to avoid sound distortion.

1486c1486,1487
< if (! num_ins || desc[0] < 6 + num_ins) {
---
> /* the magic number is '5'. */
> if (! num_ins || desc[0] < 5 + num_ins) {
"

I'd like to know how to apply the patch, but I have no idea what sound/usb/usbmixer.c is.

The KDE Info center recognizes the USB device, the kernel is said to be 2.6.17-13 mdv, if that helps, and

dmesg | grep snd command
returns
snd-usb-audio: probe of 1-1:1.0 failed with error -5
usbcore: registered new driver snd-usb-audio

Any idea how to apply this supposed patch? What is usbmixer.c and where might I find it?

Thanks
