[Alsa-devel] cs4236 (no B) and alsa 0.9.0rc7 and isapnp

[Hermann Lauer]

Dear developers,

I tried to get my cs4236 (not B) card running under 2.2.23.
One of the problems after "configure --with-isapnp" was the setting of

CONFIG_ISAPNP_KERNEL    =

in Makefile.conf, which wouldn't compile the snd-isapnp module. After setting it to "n"
the module was build and works.

Second Problem is the "half supported card" cs4236 - the website states that
the driver should be snd-cs4236, but it didn't recognize the card as
it lacks "MODE 3" mixer support - I found an old discussion that the
cs4236 driver won't work. Appended is a patch which:

- adds the signature of my PNP to cs4232 driver
- adds the String representation to the 4236 hardware id
- adds a kernel message to the cs4236 driver which prints out that
the cs4236 has not MODE3 and extended register support instead of ignoring a
cs4236 card silently.

Is that still right that the cs4232 driver is the more appropriate driver
for the cs4236 or should the cs4236 driver support also the cs4236 itself ?

Thanks for any help and your work,

Greetings
  Hermann
