[Bug 429373] Re: Sound is stuttering using libsdl1.2debian-pulseaudio and alsa packages.

[Julien Olivier]

Hi,

I've just upgraded to karmic and, while I had perfect sound in dosbox
0.73 on Jaunty, now I have crackling sound with the same dosbox 0.73.

I tried different libsdl outputs and I found out that libsdl-pulseaudio
is actually way better for me than libsdl-esd. Esd output is more
crackled and has much more latency.

I also tried removing pulseaudio completely and using libsdl-alsa, but
the result is very similar to using libsdl-pulseaudio with pulseaudio
running.

So I guess we have two problems here:
 1) libsdl-esd is broken in comparison to libsdl-pulseaudio (bad sound quality and high latency).
 2) dosbox sound is somewhat broken on karmic, independently from pulseaudio ou sdl.

I also did some tests unrelated to dosbox: I tried running sdlmame on
the same computer (the common point being SDL, of course). If I try a
CPU-intensive game, I can have the exact same problem with crackling
sound, but I don't see much difference between libsdl-pulseaudio and
libsdl-esd.

I also tried Odd (http://happypenguin.org/show?Odd), a game using SDL,
and I get perfect sound with libsdl-pulseaudio, but crackling sound with
linsdl-esd.

PS: Sorry if some information is unrelated to this bug, but I have the
feeling that maybe all the problems described are somewhat related...
