HELP: /dev/mixer and SB PCI64V

[Steffen Evers <tron@cs.tu-berlin.de>]

Hello !
I've tried to get my SB PCI64V (es1371) running under Debian 2.1 and
Kernel 2.2.10 and it won't work !
It looks like that the kernel finds the card and everything seems to be
ok, but it doesn't make any sound.
At boot time I get the following:
es1371: version v0.11 time 23:03:47 Jun 30 1999
es1371: found adapter at io 0xb800 irq 12
es1371: features: joystick 0x200
es1371: codec vendor TRA revision 3
es1371: codec features none
es1371: stereo enhancement: no 3D stereo enhancement

I was wondering if I need to use a mixer, but I don't have a /dev/mixer
or something similiar and /dev/MAKEDEV doesn't know how to make such a
device.

And sox 12.15 doesn't work either:
'sox bla.wav  -t ossdsp -w -s /dev/dsp' gives me the error message:
sox: Invalid audio buffer size 0

Is there anyone who could help me ?
