The higher cpu-usage is the faster the sound goes out-of-sync. When using mplayer in combo with this config, cpu usage goes up, and the image of the movie halts but sound keeps playing. Without this config the cpu-usage is around 20%. Tested on P4 2.8GHz. In alsa <1.0 the front and rear sound was duplicated, is it possible to reimplement that behaviour again? pcm.ch40dup { type route slave.pcm surround40 slave.channels 4 ttable.0.0 1 ttable.1.1 1 ttable.0.2 1 ttable.1.3 1 } ====================================================================== ---------------------------------------------------------------------- henkie_ - 11-10-04 22:37 ---------------------------------------------------------------------- I have this chipset according to "lspci" Multimedia audio controller: Cirrus Logic CS 4614/22/24 [CrystalClear SoundFusion Audio Accelerator] (rev 01) And i am pretty sure 0.90rc3 (not the only one though) duplicated the sound, so front and rear were exactly the same. In the windows-driver (atleast 3 years back, havent checked lately) this was also an option. And yes, it was automatically enabled. ---------------------------------------------------------------------- darkbrain - 11-29-04 15:13 ---------------------------------------------------------------------- It's true i tried alsa driver version 0.9.0b10 (in debian stable) and the signal is duplicated. From witch version this feature was disabled? I don't want to test every version to find it!
