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 - 06-20-06 23:39 ---------------------------------------------------------------------- What is the output of "cat /proc/ioports" and "lsmod"? ---------------------------------------------------------------------- El Santo - 06-20-06 23:54 ---------------------------------------------------------------------- ------------------- cat /proc/ioports 0000-001f : dma1 0020-0021 : pic1 0040-0043 : timer0 0050-0053 : timer1 0060-006f : keyboard 0070-0077 : rtc 0080-008f : dma page reg 00a0-00a1 : pic2 00c0-00df : dma2 00f0-00ff : fpu 0170-0177 : ide1 01f0-01f7 : ide0 02e8-02ef : serial 02f8-02ff : serial 0376-0376 : ide1 0378-037a : parport0 037b-037f : parport0 03c0-03df : vga+ 03e8-03ef : serial 03f6-03f6 : ide0 03f8-03ff : serial 0cf8-0cff : PCI conf1 4000-4003 : PM1a_EVT_BLK 4008-400b : PM_TMR 4010-4015 : ACPI CPU throttle 4020-4023 : GPE0_BLK 40f0-40f1 : PM1a_CNT_BLK 5000-500f : 0000:00:07.4 5000-5007 : vt596_smbus 6000-607f : 0000:00:07.4 6000-607f : via686a d000-d00f : 0000:00:07.1 d000-d007 : ide0 d008-d00f : ide1 d400-d41f : 0000:00:07.2 d400-d41f : uhci_hcd d800-d81f : 0000:00:07.3 d800-d81f : uhci_hcd dc00-dcff : 0000:00:07.5 dc00-dcff : VIA686A e000-e003 : 0000:00:07.5 e000-e003 : VIA686A e400-e403 : 0000:00:07.5 e400-e403 : VIA686A ec00-ec7f : 0000:00:09.0 ------------------- ------------------- lsmod Module Size Used by ipv6 221696 8 nls_iso8859_1 3936 1 isofs 32792 1 loop 15176 2 dm_mod 51160 0 snd_seq_dummy 3556 0 snd_seq_oss 28896 0 snd_seq_midi 8384 0 snd_seq_midi_event 6368 2 snd_seq_oss,snd_seq_midi snd_seq 44432 6 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq_midi_event shpchp 39712 0 pci_hotplug 24756 1 shpchp via_agp 9280 1 agpgart 31400 1 via_agp snd_via82xx 25688 1 gameport 13928 1 snd_via82xx snd_ac97_codec 82464 1 snd_via82xx snd_ac97_bus 2048 1 snd_ac97_codec snd_pcm_oss 45536 0 snd_mixer_oss 16448 1 snd_pcm_oss snd_pcm 77576 3 snd_via82xx,snd_ac97_codec,snd_pcm_oss snd_timer 21316 2 snd_seq,snd_pcm snd_page_alloc 9928 2 snd_via82xx,snd_pcm snd_mpu401_uart 6592 1 snd_via82xx via686a 15368 0 bt878 9656 0 snd_rawmidi 22240 2 snd_seq_midi,snd_mpu401_uart snd_seq_device 7916 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq,snd_rawmidi i2c_isa 4608 1 via686a i2c_viapro 7924 0 snd 48420 13 snd_seq_oss,snd_seq,snd_via82xx,snd_ac97_codec,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer,snd_mpu401_uart,snd_rawmidi,snd_seq_device soundcore 8928 1 snd tuner 36644 0 bttv 151600 1 bt878 video_buf 19748 1 bttv firmware_class 9696 1 bttv i2c_algo_bit 8296 1 bttv v4l2_common 5632 1 bttv btcx_risc 4520 1 bttv tveeprom 13744 1 bttv i2c_core 19280 7 via686a,i2c_isa,i2c_viapro,tuner,bttv,i2c_algo_bit,tveeprom videodev 8768 1 bttv parport_pc 32036 0 parport 31624 1 parport_pc pcspkr 1668 0 psmouse 32356 0 serio_raw 6468 0 rtc 11316 0 floppy 54628 0 joydev 8864 0 evdev 8800 2 mousedev 10496 1 ext3 117768 2 jbd 48404 1 ext3 mbcache 8484 1 ext3 ide_disk 15712 4 ide_cd 36484 0 cdrom 33280 1 ide_cd via82cxxx 8164 0 [permanent] generic 4260 0 [permanent] ide_core 112800 4 ide_disk,ide_cd,via82cxxx,generic uhci_hcd 28016 0 usbcore 113284 2 uhci_hcd 3c59x 39432 0 mii 5056 1 3c59x thermal 13416 0 processor 22912 1 thermal fan 4580 0 ------------------- 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 ====================================================================== _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-devel
