Hi SDL Gurus [?],
I have just compiled and installed SDL 1.2.14 on my ubuntu 9.04 machine.
Then i rebuild my emulator with the
new library. Every thing runs fine except that the emulator take 100% of the
CPU time. I also notice one buffer
underrun warning coming from ALSA layer. After research, i noticed that
everything runs as before if i disable
ALSA with the ./configure : ./configure --enable-alsa=NO. There is no
problem when SDL is using OSS for sound
system, the cpu load is around 15%.
Here is my question : Is it a know bug or is it a (feature?) normal thing,
because ALSA is doing very accurate polling
to limit latency or something else ? Has anyone ever had the same problem ?
Regards
