Where did my mixer controls go?


I just set up an M-Audio MobilePre USB audio device, it went quite painlessly... except for the fact that alsamixer returns

function snd_ctl_open failed for default: No such device"

and the lack of controls I have in kmix. What am I missing? In kmix, I have 2 options in the "Current mixer" tab, both called "USB Audio Class Driver". One has Volume, PCM, and Line, and the other just has Line (it's a 2 channel pre amp. Oh, and I can't play cd's either...

Have you run 'alsaconf' (as root)?

Best,

Yes, but it says no supported pnp or pci cards, and no ISA.
This is what dmesg spits out:

Advanced Linux Sound Architecture Driver Version 1.0.9b (Thu Jul 28 12:20:13 2005 UTC).
ALSA device list:
No soundcards found.

...and later on...

ALSO... with KInfoCenter I can see this under usb devices:

MobilePre

Manufacturer: M Audio
class 0 ((defined at Interface level))

Subclass 0
Protocol 0
USB Version 1.10

Vendor ID 0x763 (Midiman)
Product ID 0x200f
Revision 1.03
Speed 12 Mbit/s
Channels 0
Max. Packet size 0

but under "sound" I have

Config Options: 0
Installed drivers: ALSA emulation
Card Config: --- no soundcards ---
Audio devices: NOT ENABLED IN CONFIG
Synth devices: NOT ENABLED IN CONFIG
Midi devices: NOT ENABLED IN CONFIG

Timers: 7: system timer

Mixers: NOT ENABLED IN CONFIG

How do I enable them in config?
