hello everyone, i wonder if anyone might be able to help me or if anyone has had a similar problem. Since upgrading to potato i've been unable to get sound to work. I know looking in the archives that this sort of problem seems to occur regularly but i haven't yet found a solution.
i've got a Yamaha OPL3-SA2 chip on my motherboard (which worked under slink). My version of potato is up-to-date as of 31/05/00 and i'm running kernel version 2.2.15. I can get sound by playing audio cds directly but no other way, for instance: $ play *.wav > playing *.wav > sox: Invalid audio buffer size 0 $ mpg123 *.mp3 [..] > Can't open /dev/dsp! When i try to load the opl3sa2 module I get the following problem: $ insmod opl3sa2 io=0x100 mss_io=0xE80 mpu_io=0x300 irq=10 dma=1 dma2=3 > Using /lib/modules/2.2.15/misc/opl3sa2.o > /lib/modules/2.2.15/misc/opl3sa2.o: init_module: Device or resource busy > Hint: this error can be caused by incorrect module parameters, > including invalid IO or IRQ parameters These are the settings that i was happily using before the upgrade. 'isapnp' seems to be happy with them. My /etc/isapnp.conf file looks like: (ISOLATE) (IDENTIFY *) (CONFIGURE YMH0030/2156265473 (LD 0 (IO 0 (BASE 0x0220)) (IO 1 (BASE 0x0E80)) (IO 2 (BASE 0x0388)) (IO 3 (BASE 0x0300)) (IO 4 (BASE 0x0100)) (INT 0 (IRQ 10 (MODE +E))) (DMA 0 (CHANNEL 1)) (DMA 1 (CHANNEL 3)))) (WAITFORKEY) and "isapnp /etc/isapnp.conf" gives: > Board 1 has Identity cb 80 86 00 01 30 00 a8 65: YMH0030 Serial No 2156265473 [checksum cb] I've tried many, many other combinations of possible io/irq/dma settings to no avail. I'm stumped, especially since i can't spot any io/irq's that clash with the above choice (or any others that i've tried). $ cat /proc/interrupts > CPU0 > 0: 902274 XT-PIC timer > 1: 15151 XT-PIC keyboard > 2: 0 XT-PIC cascade > 12: 24835 XT-PIC PS/2 Mouse > 13: 1 XT-PIC fpu > 14: 78939 XT-PIC ide0 > 15: 414 XT-PIC ide1 > NMI: 0 $ cat /proc/ioports > 0000-001f : dma1 > 0020-003f : pic1 > 0040-005f : timer > 0060-006f : keyboard > 0080-008f : dma page reg > 00a0-00bf : pic2 > 00c0-00df : dma2 > 00f0-00ff : fpu > 0170-0177 : ide1 > 01f0-01f7 : ide0 > 0376-0376 : ide1 > 0378-037a : parport0 > 03c0-03df : vga+ > 03f6-03f6 : ide0 > 03f8-03ff : serial(set) > fcd0-fcd7 : ide0 > fcd8-fcdf : ide1 $ cat /proc/dma > 4: cascade As you can see the following doesn't look good: $ cat /dev/sndstat > SS/Free:3.8s2++-971130 > Load type: Driver loaded as a module > Kernel: Linux tonic 2.2.15 #1 Thu Jun 1 16:24:23 BST 2000 i686 > Config options: 0 > > Installed drivers: > > Card config: > > Audio devices: > > Synth devices: > > Midi devices: > > Timers: > 0: System clock > > Mixers: > the modules that i have got to load look like: $ lsmod > Module Size Used by [..] > opl3 11304 0 > ad1848 16752 0 > mpu401 19184 0 > sound 57452 0 [opl3 ad1848 mpu401] > soundcore 2564 3 [sound] If anyone can shed any sort of light on my problem i'd be very grateful. I currently feel like i'm going round in circles. I've read all the documentation that i can find but have not yet had any luck. That said, it wouldn't surprise me if i was doing something stupid. If there is any other information about my setup that might be relevant - i'll happily provide it. Very much looking forward to your ideas, TIA, steve -- steve felderhof ([EMAIL PROTECTED]) institute for adaptive and neural computation, division of informatics, edinburgh university. +44 (0)131 650 4492
