This patch suppresses jitter on several Maestro cards in stereo mode (ALSA of course).
The patch is also incorporated in the *BSD drivers where I "ported" it from. I am barely used to driver-development so please take a look (esp. the channel parameters), nevertheless it completely works for me.
Without this patch most of the stereo audio gets out of sync and really distorted (oss-emulation with mplayer at 48000khz worked somehow).
CCed to those listed in the .c file.
Added the alsa-devel list (and re-attached the patch). My TerraTec DMX (ESS Canyon3D, ES1970MS-3D) doesn't need this but doesn't seem to suffer from it either. Otherwise no idea about this.
This should depend on the sample rate you use. 48k would work without the patch.
Just to be clear archive-wise -- on this Canyon3D, so does 44100.
Anyway, I applied it to ALSA tree now. Thanks.
Rene.
