Can't get ALSA's amixer to access controls for a specific device on a card

Hi all,

Hope this is in the right place. I've got a VIA EPIA M10000 with an LFS system based around kernel and alsa-lib 1.0.19. Sound works for 2-channel playback but I want to start using all 6 channels that the hardware gives (VIA VT1616 AC97 connected to VT8235 south bridge).

However, the 6-channel playback is done via card 0, device 1 and I can only get amixer to access the controls of device 0 - which doesn't include the controls to enable the other four analogue outputs! (these being "Line In as Surround" and "Mic Input as Centre/LFE"

I've tried a whole load of command line arguments, but all just give me errors:

# amixer -c 0 -D 1
ALSA lib control.c:909:(snd_ctl_open_noupdate) Invalid CTL 1
amixer: Mixer attach 1 error: No such file or directory

# amixer -Dhw:0,1
ALSA lib conf.c:3843:(parse_args) Unknown parameter 1
ALSA lib conf.c:3969:(snd_config_expand) Parse arguments error: No such file or directory
ALSA lib control.c:909:(snd_ctl_open_noupdate) Invalid CTL hw:0,1
amixer: Mixer attach hw:0,1 error: No such file or directory
Generally it seems that amixer can only open the default device. So, can I use my .asoundrc to force device 1 to be the default CTL? Or is there some format of arguments that'll make it open device 1?

Any help would be greatly appreciated, I've lost far too many hours to ALSA and am starting to get a bit annoyed with it :o)

Thanks in advance,
