Bug#487900: libsdl1.2debian-pulseaudio: Sound crackles with PulseAudio (patch available)

[William Steve Applegate]

Package: libsdl1.2debian-pulseaudio
Version: 1.2.13-2
Severity: minor


Hi,

SDL programs seem to suffer from continuous crackles in their sound
stream with SDL's PulseAudio backend. From my (uneducated) point of
view, these sound like buffer underruns. Scouring the PulseAudio
maintainer's site, I found something relevant at
<http://0pointer.de/blog/projects/pa-plugin-for-sdl.html>.

I've added the patch downloaded from the linked page, rebuilt my
libsdl1.2debian* packages, and I can confirm the sound quality is much
better[*] (even though it's still far from great: Crackles are still
present, albeit less noticeable). I would thus like the aforementioned
patch to be added to the next version of this package.

[*] Actually, I also rebuilt without SVGAlib support (because I don't
need SVGAlib and the SDL packages don't even give me the opportunity to
substitute the GGI SVGAlib wrapper) and AAlib (because pbuilder had
trouble with package dependencies). I do not think these changes had
anything to do with the subject matter at hand, but I thought I'd
mention them nonetheless.


Cheers,
	-- W.
