[linux-audio-user] MIDI - hapless Newbie Q -

Please forgive me if this is somewhat OT. The tone of this group makes me wonder if I signed up for LAD by mistake. I'm having trouble with what should be a trivial soundcard config. Tech Spec: Debian-3.0/Linux-2.2.20 running on a P133 with 48mB RAM Soundcard: Bluepoint/OPTi82C930 with MAD16 Driver Problem: communicating with external MIDI device (Roland D10) [No ALSA] using OSS basic internal functionality for samples & MIDI is OK Basically every time I try to load the mpu401 driver I get told "Device or Resource busy". I've tried using modprobe, modconf and sndconfig, same thing every time. CDrom audio is also disabled, and I have errors on loading unix socket drivers (which I don't entirely understand). I've tried every available I/O & irq combination that doesn't cause conflicts. It is entirely possible that I'm just using the wrong syntax of course:~) lsmod lists pcmcia_core, unix, lockd, sunrpc, af_packet, mad16, ad1848, uart401, sound, soundlow, soundcore & joystick modules. I'm not sure if there's anything obviously missing or conflicting. Any pointers would be gratefully appreciated. I guess you'll understand when I say that a functioning soundcard is as important as video. Music will hopefully be one of the prime uses of my setup & I'm very interested in stuff like Python OSS, tse3 & stk4 & others which run happily on my box already. Csound looks interesting too, but I may need to improve my hardware before I can properly use it. Right now, I will just be happy if I can simply demo my new song. thanks in advance tim hall forgive me if I spam :~]
