Greatings, I have a usb headset, TRI-UA512 (http://www.trittontechnologies.com/products/TRIUA512.htm) which seems to be based on the C-Media's CM106 chip based on: lsusb: Bus 002 Device 006: ID 0d8c:0006 C-Media Electronics, Inc. My full `lsusb -v` is posted here: http://phpfi.com/247489 The headset works, but only in stereo, and with no hardware mixing. The output of `aplay -l` seems to indicate that it is being detected as a "generic" usb-audio device: card 1: Audio [USB Audio], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 I'm using Gentoo Linux with media-sound/alsa-driver-1.0.14_rc2-r1 media-sound/alsa-firmware-1.0.14_rc2-r1 media-sound/alsa-headers-1.0.14_rc2 media-sound/alsa-utils-1.0.14_rc2-r3 2.6.20-gentoo-r8 AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ I noticed on the cvs change log (http://www.alsa-project.org/changes/v1-0-12rc1--v1-0-12rc2.txt) that there was a patch to enable the more advanced features of the CM106. Clearly, it's not working for my specific headset. So, my question is, is there a simple way to get the usb-audio driver to recognize this as a cm106? Perhaps by adding the usb device id to the code, similar to the original patch. Or, is there something far more complicated that needs to happen? Out of curiosity, I did try to add this: if (id == USB_ID(0x0d8c, 0x0006)) { if (snd_usb_cm106_boot_quirk(dev) < 0) goto __err_val; } in usbaudio.c like in the original patch, but with my device id, but it didn't work. I would appreciate any advice. Thanks, Jon By the way, I just noticed that the change I made to the driver seemed to cause the following in the system log. Hmmm... maybe I have something wrong in /etc/modules.conf? usb 2-8: new full speed USB device using ohci_hcd and address 5 usb 2-8: new full speed USB device using ohci_hcd and address 6 usb 2-8: configuration #1 chosen from 1 choice kobject_add failed for card1 with -EEXIST, don't try to register things with the same name in the same directory.
