problem getting sound
Hello people,
I think this is the last of my confguration problems, so bare with me.
I'm trying to get my SB32 to work, obviously it's fine under windows, so
they're the values is used
after doing a pnpdump. (see below for full isapnp.conf). I've built sound
into the kernel using these
values also, and I get the initialisation click from the speakers during
boot alongside the message
Sound initialization started
<Sound Blaster 16 (4.13)> at 0x220 irq 5 dma 1,5
<Yamaha OPL3 FM> at 0x388
Sound initialization complete
Which I figure is correct. (should I have an mpu401 by any chance?)
However I also get the message
timeout attempting to read ident - is READPORT correct
Error occurred executing request 'IDENTIFY *' at or around line 19 ---
further actions aborted.
Which I figure is not so good.
This original pnpdump was done with the pnp BIOS set to use an pnp OS. Once
I turned this
option off I got sound by doing
cat endoftheworld > /dev/audio
but it was more noise than REM, but hey, it's a start.
I did a second pnpdump because of the ident message and this time the
READPORT
value was 0x020b. If I use this vaule, then during boot I see a message
about the pnp serial number of
the board which seems to be correct. Now, though if I do
cat endoftheworld > /dev/audio
I get nothing, then after a long few seconds
Sound: DMA (output) timed out - IRQ/DRQ config error?
Cat: write error: Input/Output error
So where do I go from here? I had a look at /proc/interrupts to look for a
conflict, but I didn't see any.
So now I'm puzzled. The board appears to be loading with the correct values,
but something isn't working.
Without windows I'd never had got this far, how do you set up sound cards
completely under linux?
All help gratefull received.
Thanks
