So jack is not running. IMHO it would be best to set up jackd on
your box - you'll be rewarded with excellent audio performance.

Hmm, here snd is trying to use OSS - pretty much outdated on modern
distributions/kernels. But why no alsa? Did you compile snd without
alsa support?  Note: On a Debian system you need to have libasound2-dev
installed, otherwise there won't be alsa support.
I don't think it's an alsa problem, but you can test alsa support in
your kernel with:
 $ aplay -l

This should list all alsa output devices.
To test for the precence of alsa development files, run:

 $ pkg-config --modversion alsa
