A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2219> ====================================================================== Reported By: El Santo Assigned To: ====================================================================== Project: ALSA - driver Issue ID: 2219 Category: GENERIC - mpu401 Reproducibility: always Severity: major Priority: normal Status: new Distribution: Debian etch (2006-06-18) Kernel Version: 2.6.15-1-686 ====================================================================== Date Submitted: 06-18-2006 17:41 CEST Last Modified: 06-21-2006 04:51 CEST ====================================================================== Summary: snd-mpu401 don't load Description: I have a Aopen MX63LE board with onboard sound managed by snd-via82xx driver. It loads all necesary modules, includind snd-mpu401-uart, but no snd-mpu401 The audio part of the driver works perfectly, but the midi port doesn't work. In BIOS i can set (and see) the mpu401 port (0x300 or 0x330) but there is not a MPU401 IRQ setting in bios. When i tried to manually load snd-mpu401 (setting the port accordingly to BIOS) it doesnt work. I don't know the mpu401 irq setting but i tryed them all. None of them worked. The driver says "device not found". Under windows xp the port works perfectly, so the hardware is ok. Anyway under windows xp, i use a "system inspector" to monitor ioports and irq usage, and i didnt see any irq assigned for mpu401 port, and the port (0x330) wasn't occupied neither. any idea? ====================================================================== ---------------------------------------------------------------------- rlrevell - 06-21-06 02:02 ---------------------------------------------------------------------- Please disregard my last message - try this instead (from Rene Herman) "Looking at the driver, please make him provide "mpu_port=0x330" as a parameter to snd-via82xx and check if it then works (if it does, there is a "VIA82xx MPU401" at 0x330 in /proc/ioports, and aplaymidi -l will list the MPU401 UART)." ---------------------------------------------------------------------- Raymond - 06-21-06 04:51 ---------------------------------------------------------------------- The mpu_port value must match with BIOS setup, it seem that the driver is unable to obtain BIOS setup in snd_via82xx_init_misc() Module snd-via82xx ------------------ Module for AC'97 motherboards based on VIA 82C686A/686B, 8233, 8233A, 8233C, 8235, 8237 (south) bridge. mpu_port - 0x300,0x310,0x320,0x330, otherwise obtain BIOS setup [VIA686A/686B only] Issue History Date Modified Username Field Change ====================================================================== 06-18-06 17:41 El Santo New Issue 06-18-06 17:41 El Santo Distribution => Debian etch (2006-06-18) 06-18-06 17:41 El Santo Kernel Version => 2.6.15-1-686 06-19-06 03:45 Raymond Note Added: 0010305 06-20-06 19:49 tiwai Note Added: 0010349 06-20-06 23:30 El Santo Note Added: 0010357 06-20-06 23:39 rlrevell Note Added: 0010359 06-20-06 23:54 El Santo Note Added: 0010362 06-21-06 00:00 rlrevell Note Added: 0010363 06-21-06 00:04 rlrevell Note Added: 0010364 06-21-06 00:12 El Santo Note Added: 0010365 06-21-06 00:18 rlrevell Note Added: 0010366 06-21-06 00:33 El Santo File Added: dmesg.log 06-21-06 00:36 El Santo Note Added: 0010367 06-21-06 00:52 rlrevell Note Added: 0010369 06-21-06 00:56 rlrevell Note Added: 0010370 06-21-06 02:02 rlrevell Note Added: 0010374 06-21-06 04:51 Raymond Note Added: 0010379 ====================================================================== _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-devel
