Bug#483451: fretsonfire: guitar track not heard; background track used as guitar track

[Timo Jyrinki]

The problem occurs regardless of whether one uses libsdl1.2-debian-alsa, 
-esd or -pulseaudio. However, the workaround of using 8-bit samples 
seems to only works when using SDL's ALSA backend, ie. esd/pulseaudio 
have some problem(s) with 8-bit samples.

In related news, using the ALSA backend with pulseaudio installed makes 
the FoF screen scroll jerkily, so the 8-bit functionality of SDL's 
esd/pulseaudio backends would also be welcome for the workaround to work.

Anyway, the real problem with amd64 and 16-bit samples is probably quite 
simple, but at least I cannot say whether it's in FoF, pygame or SDL.
