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: 06-20-2006 23:30 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? ====================================================================== ---------------------------------------------------------------------- tiwai - 06-20-06 19:49 ---------------------------------------------------------------------- Usually snd-mpu401 can be loaded without module options using ACPI PnP. ---------------------------------------------------------------------- El Santo - 06-20-06 23:30 ---------------------------------------------------------------------- Hi again! My message had a typo: the motherboard is not AOpen MX63LE, but AOpen MX36LE. I also tryed to load the module without parameters.... modprobe snd-mpu401 FATAL: Error inserting snd_mpu401 (/lib/modules/2.6.15-1-686/kernel/sound/drivers/mpu401/snd-mpu401.ko): No such device FATAL: Error running install command for snd_mpu401 ... and a "MPU-401 device not found or device busy" is added to syslog the outputs of the commands: ------------------ aplaymidi -l Port Client name Port name 62:0 Midi Through Midi Through Port-0 ------------------ cat /proc/asound/cards 0 [rev50 ]: VIA686A - VIA 82C686A/B rev50 VIA 82C686A/B rev50 with AD1885 at 0xdc00, irq 10 ------------------ lspci -vn 0000:00:00.0 0600: 1106:0601 (rev 05) Flags: bus master, medium devsel, latency 8 Memory at e0000000 (32-bit, prefetchable) [size=64M] Capabilities: <available only to root> 0000:00:01.0 0604: 1106:8601 Flags: bus master, 66MHz, medium devsel, latency 0 Bus: primary=00, secondary=01, subordinate=01, sec-latency=0 Memory behind bridge: e4000000-e6ffffff Prefetchable memory behind bridge: 20000000-200fffff Capabilities: <available only to root> 0000:00:07.0 0601: 1106:0686 (rev 40) Subsystem: 1106:0000 Flags: bus master, stepping, medium devsel, latency 0 Capabilities: <available only to root> 0000:00:07.1 0101: 1106:0571 (rev 06) (prog-if 8a [Master SecP PriP]) Subsystem: 1106:0571 Flags: bus master, medium devsel, latency 32 I/O ports at d000 [size=16] Capabilities: <available only to root> 0000:00:07.2 0c03: 1106:3038 (rev 1a) Subsystem: 0925:1234 Flags: bus master, medium devsel, latency 32, IRQ 5 I/O ports at d400 [size=32] Capabilities: <available only to root> 0000:00:07.3 0c03: 1106:3038 (rev 1a) Subsystem: 0925:1234 Flags: bus master, medium devsel, latency 32, IRQ 5 I/O ports at d800 [size=32] Capabilities: <available only to root> 0000:00:07.4 0680: 1106:3057 (rev 40) Subsystem: 1106:3057 Flags: medium devsel, IRQ 9 Capabilities: <available only to root> 0000:00:07.5 0401: 1106:3058 (rev 50) Subsystem: 11d4:5360 Flags: medium devsel, IRQ 10 I/O ports at dc00 [size=256] I/O ports at e000 [size=4] I/O ports at e400 [size=4] Capabilities: <available only to root> 0000:00:09.0 0200: 10b7:9200 (rev 78) Subsystem: 10b7:1000 Flags: bus master, medium devsel, latency 32, IRQ 11 I/O ports at ec00 [size=128] Memory at e8000000 (32-bit, non-prefetchable) [size=128] Expansion ROM at 20100000 [disabled] [size=128K] Capabilities: <available only to root> 0000:00:0f.0 0400: 109e:036e (rev 11) Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at e8001000 (32-bit, prefetchable) [size=4K] Capabilities: <available only to root> 0000:00:0f.1 0480: 109e:0878 (rev 11) Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at e8002000 (32-bit, prefetchable) [size=4K] Capabilities: <available only to root> 0000:01:00.0 0300: 1023:8500 (rev 6a) Subsystem: 1023:8500 Flags: bus master, 66MHz, medium devsel, latency 32, IRQ 11 Memory at e5800000 (32-bit, non-prefetchable) [size=8M] Memory at e6000000 (32-bit, non-prefetchable) [size=128K] Memory at e5000000 (32-bit, non-prefetchable) [size=8M] Expansion ROM at 20000000 [disabled] [size=64K] Capabilities: <available only to root> ------------------ Regards 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 ====================================================================== _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-devel
