[NTLUG:Discuss] Sound problems

[Tom McDonald,]

I have a Dell OptiPlex GX1 with a Crystal CS4236 onboard sound chip and 
I'm having problems getting it setup.  Hoping someone here may have some 
pointers.

I'm running Mandrake 7.2 with GNOME and Helix - I was running the esd 
sound, and have had it working in the past with OSS also.

The sound system was working fine with this arrangement until a week ago 
when I tried to convert some mp3's to cdr format. I was using mpg123 to 
convert the mp3's and had about 10 processes going.  The process hung so 
I killed them and noticed that the sound wasn't working anymore.

I've done the following to try to get it setup again;

	- Turned off the system to allow cold boot initialization
	- Re-installed OSS from a fresh download
	- Run sndconfig and modified the settings
	- Uninstalled the OSS and esd sound systems and installed alsa
	- Compared the settings in /proc to the modules configuration
	- Made sure the PCM and speakers etc were all un-muted
	- installed the modules by hand one by one
	- Confirmed the BIOS setting has the sound card turned on
	- Run xmms and checked that the wave forms appeared normal

The only thing I haven't been able to check is the hardware itself.

alias char-major-116 snd
alias snd-card-0 snd-card-cs4236
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 snd_device_mode=0660 
snd_device_gid=81 snd_device_uid=0
options snd-card-cs4236 snd_index=0 snd_id=CARD_0 snd_port=0x534 
snd_cport=0x127 snd_mpu_port=0x330
alias sound-slot-0 cs4232
options sound dmabuf=1
alias midi opl3
options opl3 io=0x388
options cs4232 io=0x534 irq=5 dma=1 dma2=0 mpuio=0x330 mpuirq=7

I used isapnp reports success when I initialize it with the above 
parameters, then when I load the modules I get no errors, /etc/messages 
etc. but still no sound.

I installed the oss services at the suggestion of the alsa howto, but I 
have also tried it without them.

Any hints or suggestions?

Tom
