Hi there,
I am having some problems with a ISA plug and play sound card using alsa
0.9.3 with kernel 2.4.20. The card is a snd-opti92x-ad1848.
With alsa 0.9.0rc3 and kernel 2.4.29 the card worked fine. Even the
isapnp stuff worked without problems. However with alsa 0.9.3 and kernel
2.4.20 it does not work. The card is not found by alsa. I checked
/proc/isapnp and found out that the card isn't initialized by isapnp at
all. I initialized the card manually with isapnp using the values for
IO, IRQ and DMA that worked for alsa 0.9.0.rc3. However with no success.
Any ideas what might be the problem? Have there been changes in isapnp
support between alsa 0.9.0.rc3 and 0.9.3?
Here is some more system information:
