Hello everybody,
I am trying to use udev to get fixed device names depending on the
location of the device on the usb bus. The udev rules seems to be
working fine, however i cant get dmix to work with the udev rules using
only hw dies work. If i remove the udev rules the dmixer works fine.
Can somebody look at the attachment, and maybe do some testing, i would
highly appreciate it.
I am also on chat.freenode.org and #alsa as tuxcrafter
Thanks in advance,
Jelle
