I've recently changed my hardware from an Epox mobo (with VIA V82C686 chip)to an Asrock K7VT4A Pro (with VIA V8237 chip) and have run into problems with getting MIDI data in through the 15-way D-type connector. Alsa is compiled with via82xx and mpu401 (and alsi virmidi and serialmidi, for other reasons) enabled. The old mobo running Alsa 1.0.9b loaded snd-mpu401 and all was fine; the new mobo refuses to load snd-mpu401 - modprobe fails, saying that there's no such device. I've tried upgrading to Alsa 1.0.11 but to no avail. Kernel is 2.4.31 and I'm running a slightly modified Slackware 10.2.
Looking in /proc/ioports, I can't see any port listed at 0x330, which is where the Asrock's BIOS says the MIDI port is located and using IRQ5. To check the hardware, I've booted the new mobo to DOS (yes - DOS!!) and have run a small Turbo Basic program to prove that I can read MIDI coming through the 15-way D-type, so I'm confident that the new mobo does actually have the necessary hardware and that it's working. Please could anyone offer any help to get the MIDI input working with the Asrock mobo and Alsa? I'm no longer able to go back to the old mobo, so this is rather important to get working. I've run out of ideas to try! The relevant section of /etc/modules.conf I've listed at the end of this msg, in case it's of any interest. Thanks for any clues, Gerald. ############################################################################## # (Part of /etc/modules.conf) # # ALSA native device support: alias char-major-116 snd options snd major=116 cards_limit=3 ### With old Epox m/b - this worked: ### alias snd-card-0 snd-via82xx ### options snd-via82xx mpu_port=0x330 ### With new Asrock m/b - no MIDI input working: alias snd-card-0 snd-via82xx options snd-via82xx dxs_support=4 options snd-mpu401 enable=1 port=0x330 irq=5 # OSS/Free setup alias char-major-14 soundcore alias sound-slot-0 snd-card-0 # First card (card 0) alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss # Second card (card 1) - virtual MIDI card alias sound-slot-1 snd-card-1 alias snd-card-1 snd-virmidi # 3rd card (card 2) - serial MIDI alias sound-slot-2 snd-card-2 alias snd-card-2 snd-serialmidi options snd-serialmidi sdev="/dev/ttyS1" speed=57600 ############################################################################## _______________________________________________ Alsa-user mailing list Alsa-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/alsa-user
