Audio output seems like it is being played very slowly, more of a variable
frequency buzzing with clicks, with VMIX disabled through ossmix, the audio
is played at almost the correct speed but has replay echoes and crackling.
Moving the mouse, or accessing the disk (find, ls, etc) pretty much corrects
the audio speed, removes the replay echoes, leaveing some clicks. The audio
output then reverts to above broken modes when mouse movement/disk access stops.
ossplay'ing the same audio test song generates the same number of interrupts
regardless of whether running in broken mode or almost correct, with find(1)
accessing the disk.
Adjusting vmix0-src, vmix0-channels, max_intrate, src_quality and dma_buffsize
doesn't appear to make any difference.
Neither does changing kernel clocksource and noapic, etc.
ossinfo -v3 and ossmix info posted under same subject on 4-Front Linux forum.
I'd appreciate any ideas you may have on this.
thanks.
