I am running asterisk on debian Etch , i486 with math emulation in kernel. Verified by /boot/config-file. I am getting a seg fault in alsa. First I ran straight debian with alsa install. I got the same seg fault. Second I installed 1.0.16 and I still get the seg fault. Third I installed 1.0.17rc2 and I still get the seg fault. Posted to users first and stan suggested I post to devel.
Below is the trace. I am only using the Console/Dsp from asterisk at this point. Which is the interface to the soundcard and alsa. What shall I do?

This seems to be 100% realted to usb-audio. I Bus 002 Device 003: ID 0d8c:000c C-Media Electronics, Inc. Audio Adapter
I had a centos box worked fine. I disabled the on board audio. put my usb device in and it is behaving the same way. plays wave files but asterisk dies.
I have been searching for a know issue on this or fix but have not found one yet.
Any help is appreciated.
