Default ALSA fail on wheezy.

I'm running testing

$ cat /proc/version | fmt
Linux version 3.0.0-1-686-pae (Debian 3.0.0-1) (ben@decadent.org.uk)
(gcc version 4.5.3 (Debian 4.5.3-3) ) #1 SMP Sun Jul 24 14:27:32 UTC 2011

$

on a ibm thinkpad a22m that's got one of these

$ lspci | grep -i audio | fmt
00:05.0 Multimedia audio controller: Cirrus Logic CS 4614/22/24/30
[CrystalClear SoundFusion Audio Accelerator] (rev 01)

$

and have installed ALSA

$ dpkg -l | grep -i alsa
ii alsa-base 1.0.23+dfsg-4 ALSA driver configuration files
ii alsa-oss 1.0.17-5 ALSA wrapper for OSS applications
ii alsa-utils 1.0.24.2-1 Utilities for configuring and using ALSA
ii bluez-alsa 4.94-3 Bluetooth ALSA support
ii libasound2 1.0.24.1-2 shared library for ALSA applications
ii linux-sound-bas 1.0.23+dfsg-4 base package for ALSA and OSS sound systems

$ lsmod | grep snd

snd_page_alloc 12899 2 snd_cs46xx,snd_pcm

$

But it's not working at all

$ alsamixer
cannot open mixer: No such file or directory

$ ls /dev | grep -i mix

$ aplay /usr/share/sounds/alsa/Noise.wav
ALSA lib confmisc.c:768parse_card) cannot find card '0'

$ cat /proc/asound/cards
29 [ThinkPadEC ]: ThinkPad EC - ThinkPad Console Audio Control
ThinkPad Console Audio Control at EC reg 0x30, fw unknown

$

These commands also fail for root in the same way, and yes

$ groups
rclayton cdrom floppy audio dip video plugdev netdev bluetooth

$

What is the explanation for the evident mixer and card problems, and how do I
fix them?

The 'fw unknown' is bothersome. I'd take 'fw' to be 'firmware'.

The Debian Wiki is often very useful:

You're probably right; had I looked at dmesg, I would have seen that cs64xx
had no firmware.

It was for me; it solved the problem. Thanks for your reply to my message.
