OPL3-SAx sound CLIPPING/SKIPPING under HDD+MOUSE activity
Hi & HELP!
I got a laptop(K6-23D 333+64Mb RAM S3 virge mg/mx) with a OPL3-SAx(yamaha 719)
sound chipset. It works perfectly under win98, but i dont use 98. The problem
is that sound through dsp device is clipped/disturbed by HDD+MOUSE activity in
X and X-free sessions! Iam using kernel 2.2.x and compiling with modular
OPL3-SAx support and initializing the card with isapnp since its a PnP chipset.
I havent been able to figure out the obvious I/O conflict but iam not a HEX
master so I have pasted in some of my /proc/ files from a
system where i can get sound(mp3 eg) but clipping and skipping of the output
then i move the mouse or there is harddisk activity( it dosent seem to be a CPU
dependent prob).
please help I need sound on my mobile-LinuxBOX :)!!!
