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@xxxxxxxxx>:
Well there was nothing about gameports or MIDI ports in the BIOS except that they were "enabled" so I'm not sure how else to find the physical address of the port. Perhaps I just need to put more research time into finding a module to enable it in the OS, but if it's not a serial port then what is it? > The serial ports have nothing to do with MIDI. > The MIDI port should be listed under "gameport" or "MIDI" or "MPU-401". -- -----BEGIN GEEK CODE BLOCK----- Version: 3.12 GCA/FA/S/O d+(--) s+: a-- C+++ L++ P E-- W++ N- o K? w O-- M- V- PS+ PE- Y+ PGP t- 5-- X R- !tv b++ DI++ D+ G+ e+/++ h--- r--/+++ z+++(*) ------END GEEK CODE BLOCK------
