Re: [linux-audio-user] Midi Woes

Hi Clemens, try those 3 commands as root from a sheel: "rmmod snd-mpu401 snd-mpu401_uart" "modprobe mpu_port pnp=1" Make sure no appliction is using the midi port before entering the above commands. then type this command: "cat /proc/interrupts /proc/ioports |grep MPU" The last command should output dma and IRQ addresses of your mpu interface. That's what it outputs in my case: cat /proc/interrupts /proc/ioports | grep MPU 5: 14 IO-APIC-edge MPU401 UART 0330-0331 : MPU401 UART The MPU is sitting at dma is 5 on IRQ 0x330. And those are the very same values I have the MPU401 setup in my bios. Not that it matters, it should work already, as in: $~/ pmidi -l Port Client name Port name 14:0 Midi Through Midi Through Port-0 20:0 MPU-401 UART MPU-401 UART MIDI The problem in my case is it doesn't work... Onboard MPU401 has never worked too well for me in the latest kernels, tested on a an asus nforce2 based MB and on an ASRock "el-cheapo" SIS7012 based MB, both of them using the intel8x0 sound module. It doesn't work in that if I try playing a midi file the kernel complains on syslog about weird erros. That kinda worked with the older alsa versions that still had the "mpu_port" parameter for the onboard sound module. The midi port worked for some random amount of time untill it completely locked my box. I tested this under various distros. I am thinking about buying an extrenal/USB midi box, I am stuck without midi right now. Hopefully you'll be luckier than I was. Cheers, -gzed 2006/11/10, Chip VanDan <chip.vandan(a)gmail.com>om>:
