Cirrus Logic Crystal Audio (cs4235)

Description: The Crystal Audio (cs4235) is manufactured by Cirrus Logic. This audio chipset was found in an IBM 300PL. The 300PL has an integrated speaker as well as a phone jack either in the back or the front depending on the generation you have.

In a stock, slackware 10.0 system I found the module here:

/lib/modules/2.4.26/kernel/sound/isa/cs423
did
"modprobe snd-cs4236"
and linux did the rest.

The kernel module is smart enough to turn the internal speaker off when you plug in something in the 1/8" phone jack in the back.

Unfortunately this intergrated chip was not detected and autoconfigured by slackware.

I could not visually identify the chip on the motherboard.

This device is not listed by lspci, and can be found by running pnpdump; the only intelligible part of the dump is a string of text that says "Crystal Audio" but does not list the part numer (cs4235).

Since IBM produced a million of these 300pl's over the years and there seems to be no way to tell them apart, you could have another chipset in your 300pl; I have tried the maestro 3, ac97 and others as suggested on the internet but none work except snd-cs4236.
