Yes, I think it is related, but this message can hide different problems
related to Alsa.

Ok, it confirms that is a problem with alsa.
You have this output because alsa is not installed.

What you describe me here would explain why I cannot reproduce this
bug, it is probably a specific problem related to sound cards and alsa.
It seems to be an alsa bug with severals sound cards models.

I tested fmit with latest Debian Unstable on theses machines:
- A PC (x86) with Opti Sound Card (16bit with Soundblaster 16
compatibility):
Chipset: C-Media Electronics Inc CM8738 (rev 10)
- An Apple iBook G3 (PowerPC) with integrated sound card (16 bit).
Chipset: PowerMac Snapper
- An Athlon64 (AMD64) with Sound Blaster Audigy2.
Chipset: Emu10k1
I tried to run fmit on theses machines without alsa, and after,
with alsa.
On all theses machines, fmit works without problems.
