There are two Plug&Play sound cards on this system and
ISAP&P sees them. If I insert a PCI sound card and power up, the
CS4236 gets IRQ 5 and the SoundBlaster gets zilch. Reading
available documentation, it looks like this is because older ISA
cards may not be able to report enough back to the system to get
the correct resources so one must stuff the correct values for
irq, port address and DMA lines in to parameters for snd_sbawe.
I can force the SB16 to come on line if I remove the
module for the cs4236 and make the SB16 Card 0 and then the
CS4236 is high and dry and then it won't show up.
Here is what each card allocates when it is working and
is Card 0
# 0 [CS4236B ]: CS4236B - CS4236B
# CS4236B at 0x534, irq 5, dma 1&3
# 0 [S16 ]: SB AWE - Sound Blaster 16
# Sound Blaster 16 at 0x220, irq 5, dma 1&5
If I can make them both work, the SB16 which should be card 1
will need a different IRQ for sure and maybe different DMA's.
I was able to install a PCI sound card temporarily which
does allocate resources but is unusable due to bad hardware on
the right channel or I would have used it and been done with the
whole thing.
It got IRQ 9.
When I feed the sbawe parameters, should they be fed in
to the /etc/modules file where snd_sbawe is entered or should I
put them in /etc/modprobe.d/alsa-base.conf after the INDEX=1
parameter?
When the SB is forced to be Card 0, it does appear to work but I
haven't tried much with it since that is not the way it is going
to work if it ever does work.
Thanks and I am gradually beginning to figure out at
least what the problems are.
