choppy, cracking sound on Haiku

[farvardin]

I can play ogg vorbis or mp3 files with the MediaPlayer. But the sound is choppy and cracks quite much. I noticed if I disable a CPU (it's an amd64 dual core), it sounds a bit better. Yet if I do something on the system (right clicking on the ProcessController, clicking on a tab in Firefox/BeZilla), then the sound is even more degradated, as if my computer was not powerful enough to handle this.

(this issue was discussed on: ​http://www.haiku-os.org/community/forum/playing_music )

I noticed also when turning the "real time audio" off, and restarting the media_server, the sound seemed slightly better too (and when I reboot Haiku, the real time audio option is checked again)

I'm running Haiku on real hardware, and the music files are stored on the BeOS partition (on the Desktop). I have 2 Gb of Ram.
