Thinkpad 770 sound not working

#1 Post by sindi »

Thinkpad which plays sounds nicely in Win95 is known to have Crystal isapnp chip which uses cs4232.

ALSA setup identifies the card and loads the drivers but when I try to play aplay *.wav: ALSA lib
confmisc.c:768:(parse_card) cannot find card '0' ..... No such device.......

I then tried it as sb8 since it does sb emulation. No luck. There is an alsa cs423x
module.


Puppy 4.31 kernel 2.6.21.7. 4.21 could not find its files and 4.31 2.6.30 'small' rebooted endlessly.

In Basiclinux you have to specify the kernel location when using loadlin (c:\bl2\zimage not just zimage), which is
unusual.

In Basiclinux,2.4 kernel, the OSS modules load and it appears to play but no sound emerges.

insmod soundcore
insmod sound
insmod ad1848
insmod uart401
insmod cs4232 io=0x530 irq=5 dma=0 dma2=1 (and optional mpu and midi stuff)

I found similar instructions for Puppy 1.05 with OSS.

Other people had this Thinkpad working with Redhat and Debian, and sound.

Search seems to be broken at the forum. Where and how can I manually specify the io and irq for this isapnp chip?

Crystal sound cs423x has not worked in any of my computers with Puppy, including desktops, with 4.31 2.6.21.7. 4232 and
4236 cards. The PCI versions do work in Basiclinux but not Puppy.

Puppy sound also does not work with a 400MHz Thinkpad.

Note, especially, that your bios must be set for "QuickBoot = OFF" or ""ThinkPad Simple Boot = OFF".

Thinkpad 770 with CS4232

alsaconf identifies the card
correctly but then you need to
point it at 'legacy' and uncheck
all but cs4232 on the list.
Same for other nonpnp laptop
sound such as opl3sa2.
