Re: hdspmixer segfaults on AMD64

[Mark Knecht <markknecht@gmail.com>]

Hi Lee,
   I downloaded alsa-tools-1.0.10-rc1 and built just the hdspmixer app
from that tarball. Same segfault. I have a fairly useless (I think)
back trace. I haven't figured out how to get good symbols. (I'm not a
programmer - sorry!)

Here's what I have so far, the important point being that it segfaults
exactly like the one in 1.0.9.

Thanks,
Mark
