Comment (by tjyrinki):
This one pointed me in right direction, thanks. Indeed FoF uses pygame
which uses SDL. It seems Ubuntu still defaults to libsdl1.2debian-alsa
instead of -esd or -pulseaudio. The -pulseaudio is not in main (supported)
repository yet.
Anyway. With -esd or -pulseaudio libsdl the problem, mostly (see below),
disappears. Is libsdl1.2's ALSA variant not supported by pulseaudio or
should it also work? Regarding this bug, if SDL's ALSA output plugin is
not within the safe subset of ALSA, this bug itself does not exist anymore
since esd and pulseaudio plugins work. Which is nice.
Using -esd or -pulseaudio however brings forward another bug/problem with
pulseaudio which still prevents its usage in this problematic case... The
background is that for some reason, FoF/pygame/sdl has a bug that using
16-bit samples on x86-64 prevents some of the audio from playing (if you
hit wrong notes, the music in the background totally stops while it
shouldn't). The only solution to the problem so far has been to select
8-bit samples into use from FoF settings (yes, it sucks, but it's the only
solution found currently).
However, with libsdl1.2debian-esd, Pulseaudio and 8bit samples the sound
is garbled/cracking a lot. With libsdl1.2debian-pulseaudio and 8bit
samples the Frets on Fire simply does not start, instead hanging without
error message, probably in some audio subsystem initialization. Libsdl1
.2debian-alsa works fine, but exhibits the original problem presented in
this bug if pulseaudio is installed.
Is lack of 8-bit sample size support a known issue in Pulseaudio, or
should I file a bug about it now?
