Please merge snd-cs4236 initscript portion for ThinkPad 600s

robert@elephant:~$ aplay /usr/share/sounds/startup.wav
Playing WAVE '/usr/share/sounds/startup.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
aplay: pcm_write:1222: write error: Input/output error

That above is why I am filing this bug report. I cannot play any sounds or record sounds, though I can use alsamixer to make it so that I can hear myself talking into the microphone and cause a lot of feedback.

Before I upgraded to dapper I was using the OSS cs4232 module because I did not want to read about how to configure alsa. That driver is no longer available though it seems so I am using snd-cs4236 by adding the following to rc.local (probably not the right way, but it seems to load without errors, which should be a bug because it doesn't work):

## setup the sound card
setpnp 0e on && setpnp 0f on && setpnp 10 off || exit 1
OPTIONS="index=0 isapnp=0 port=0x530 cport=0x538 irq=5 dma1=1 dma2=0"
modprobe snd-cs4236 $OPTIONS || exit 1

AFAIK my system is as updated as possible as of this time of this writing.

Also, I tried switching the dma's as mentioned here: http://alsa.opensrc.org/index.php?page=ThinkPad600
and it did not make any difference.

[Robert McMeekin (rrm3)]

With 2.6.15-22, I no longer get the input/output error. aplay just hangs and doesn't make any noise. Rhythmbox just hangs too (the status says it's playing, but the numbers and progress bar do not move, this behavior did not change between the 21 and 22 kernel release).

[Robert McMeekin (rrm3)]

Nevermind, the behavior only changes when I have esd enabled. Without esd enabled, the same results occur as described in the original report.

Finally, problem fixed with script found here and after I removed some bogus lines that I had added by mistake to /etc/modprobe.d/alsa-base (sorry): http://www.thinkwiki.org/wiki/Problem_with_broken_sound_on_ThinkPad_600. with the following changes:

Sorry, to clarify: the original bug was my mistake throwing the wrong options when modprobing snd-cs4236, but I wonder if that script or at least parts of it could be somehow included in the distribution to prevent headaches for other people.
