Hi,
Got some sound issues with puaex on my laptop (ubuntu 9.04 - 2Ghz dual core).
I don't have this issue with E-uae.
When sound is activated, the scrollings are choppy. When the sound is
disabled or "disabled but emulated", the scrollings are super smooth
(maybe even too fast compared to the original - have to check that).
I use a good example of logo horizontal scrolling on this demo [1] (
but any text scrolling will do )
What I tried :
- compiling with ./configure --with-sdl --with-sdl-gfx --with-sdl-gl
--with-alsa
- compiling with ./configure --with-sdl --with-sdl-gfx --with-sdl-gl
--with-sdl-sound
- disabling pulseaudio
With sdl-sound I tried this :
- installing libsdl1.2debian-pulseaudio then launching
SDL_AUDIODRIVER=pulse puaex
- installing libsdl1.2debian-oss then launching SDL_AUDIODRIVER=oss puaex
- tried different settings in the gui
- tried different values for sound_stereo_separation
- tried different values for sound_stereo_mixing_delay
- tried disabling filter emulation, ...
All of the above could not help. Then I tried playing with
sound_latency which default to 100 ( I never touched to this value
before )
Lowering the latency also lower the choppy effect.
I could go as low as 10 as a normal user without making puae crashes.
I could get a bit lower with root privileges.
IIRC kernel 2.6.31 will have low latency facilities, maybe it'll
change something.
Anyway, when I try with E-uae (default latency 100 with alsa) the
scrollings are smooth.
While latency=10 helps puaex in my case, I can't get it as smooth as
E-uae with default latency (100)
Am I the only one to have this problem ? Does someone has a suggestion ?
Just lauch the demo with puaex then with e-uae and play with
disabling/enabling sound in the gui while the logo is scrolling,
you'll (probably) see what I mean.
