Description of problem:
Per request from, bug #53293
was re-opened for RHEL 4.

I am running RH 7.1 on an IBM ThinkPad 770Z and a cs4232 sound chip.
UnderRH7.1 the CD plays music just fine.  However sound programs such
as play or XMMS either fail to play anything at all or what they produce
skips and stuffers so bad as to be unrecognizable.

This same lack of sound problem exists in RHEL3 WS.

Comment 1 Pete Zaitcev 2005-05-13 18:23:28 UTC
What is the exact version of kernel and pcmcia-cs on the box?
Please run rpm -q kernel and rpm -q pcmcia-cs to get versions.

Comment 2 Landon Curt Noll 2005-05-14 19:05:14 UTC
$ rpm -q kernel pcmcia-cs

Comment #13 from bug #53293 no longer fixes the problem:

Under RHEL3 and prior (pre-ALSA) I had to make changes to
the old /etc/modules.conf file (see Comment #4 from bug #53293 ).
Obviously those lines no longer apply for RHEL4.  Is there some
equivalent lines tha I need to add to /etc/modprobe.conf to
get sound working under RHEL4 for the ThinkPad 770Z?

Comment 3 Pete Zaitcev 2005-05-14 19:48:19 UTC
I suggest something like this:

alias char-major-116 snd
alias snd-card-0 snd-cs4232
alias char-major-14 soundcore 
#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-pcm1-oss 
#alias sound-service-0-12 snd-pcm1-oss 
#alias synth0 opl3 
#options sound dmabuf=1 
#options snd snd_major=116 snd_cards_limit=1 snd_device_mode=0666
snd_device_gid=0 snd_device_uid=0
#options opl3 io=0x388 
#options snd-cs4232 port=0x530 mpu_port=0x330 irq=5 mpuirq=7 dma=1 dma2=0

Note that I left options to snd-cs4232 commented because it should
be PnP capable and not needing any explicit settings.

Old xmms binaries may need OSS emulation, I'm not sure how well that
works. Please try with something like aplay or mpg321 first. Once that
works, xmms can be brought into picture.
