I hope someone can point me in the right direction on this, as I
can't be 100% sure I've not just overlooked something (I'm by no
means an expert etc.). I get errors with alsamixer/amixer that
prevent sound from working on this machine:
Linux boxname 2.6.18-4-amd64 #1 SMP [...] x86_64 GNU/Linux
(Debian 2.6.18.dfsg.1-12etch2)
When I run alsaconf, before 'Have a lot of fun!', I get: [...]
Setting default volumes...
amixer: Mixer default load error: Invalid argument
Saving the mixer setup used for this in /var/lib/alsa/asound.state.
/usr/sbin/alsactl: get_control:209: Cannot read control info '2,0,0,Capture
Volume,0': Invalid argument
Accordingly, asound.state is not created (/var/lib/alsa/ is empty).
Output of 'amixer controls |grep Capture' is:
amixer: Control default snd_hctl_elem_info error: Invalid argument
numid=3,iface=MIXER,name='Capture Switch'
I'll append an strace of running 'amixer', which simply outputs an
'Invalid argument' error. Applications like xmms and aplay run
without apparent error, as if sound's just muted, which it probably is.
/proc/asound/version :
Advanced Linux Sound Architecture Driver Version 1.0.12rc1
The only apparently relevant line from the usual logs is:
hda_codec: num_steps = 0 for NID=0x17
I don't know what other information might be useful. The output of
an 'lsmod |grep snd' is:
snd_hda_intel 23708 0
snd_hda_codec 184192 1 snd_hda_intel
snd_pcm_oss 48672 0
