audigy and alsa -> amixer crashes

[daen]

hi,

i'm trying to get alsa working and so i followed the desktop configuration guide. it seems that the card gets initialized properly (/proc/asound has lots of entries :)
but - amixer SIGSEGVs...

is there another way to unmute the card or does anyone has a hint for me ?

thanks,
daniel

I'm also getting seg faults from amixer. I was able to unmute the card with kmix, after which I could play sounds with aplay. (artsd won't start for me, so I can't use artsplay. I haven't figured that one out yet.)

I note that your lsmod shows snd-emu10k1, which is the module used in the example in the Desktop Guide. Just wondering if, by coincidence, that is also the card in your box, or if perhaps you haven't yet edited /etc/modules.d/alsa to replace snd-card-emu10k1 with the module for your sound card.

[daen]

as far as i know is emu-10k1 for the audigy too. in /proc/asound is see that the card as audigy is being recognized.
i also tried it with kmix, but i only get a mixer for my tv-card...

bye,

I have problems with amixer too and I'm also using the manual for Sound.
This where it goes wrong:
