Hello .... 
At first im Newbie
I have a 600E and canīt get any sound out of it...
I have installe Suse 9.0 and automatic the Driver CS4610 is installed, but it doesnīt work.....
I thougt I have done everything that Suse Support says.....

Sound chipset: Multimedia audio controller: Cirrus Logic CS 4610 (rev 01) 
Works with the kernel driver for cs4232 in the emulation mode. No special settings are necessary to achieve the emulation mode. 
One needs the following lines in /etc/conf.modules 

alias char-major-14 cs4232 
options cs4232 io=0x530 irq=5 dma=1 dma2=0 

to get wav and mp3 file playing working. The driver will not survive an APM suspend / resume, reload it after an suspend / resume. 
Quality of sound is even better than on my desktop PC. 
ALSA of 6.4 (0.5.5+) works with the following modules.conf entries: 

alias char-major-14 soundcore 
alias char-major-116 snd 
alias snd-card-0 snd-card-cs4236 
alias sound-slot-0 snd-card-0 
alias sound-service-0-0 snd-mixer-oss 
alias sound-service-0-1 snd-seq-oss 
alias sound-service-0-3 snd-pcm-oss 
alias sound-service-0-8 snd-seq-oss 
alias sound-service-0-12 snd-pcm-oss 

options snd snd_major=116 snd_cards_limit=1 
options snd-card-cs4236 snd_index=0 snd_port=0x530 snd_cport=0x538 snd_irq=5 snd_dma1=1 snd_dma2=0 snd_isapnp=0 

post-install snd amixer set Master 100% unmute;amixer set PCM 100% unmute; amixer set Aux,1 100% unmute 

Aux,1 is the Channel for CD-in, APM suspend / resume support for the Thinkpad will be included in future ALSA releases. 
Currently do an rcalsasound restart after an suspend / resume cycle. 

After the rcalsasound restart an Error is comming .....canīt locate module cs4236.... 

Please Help.....
