sound problems!!!

[Jeffrey Ross]

I've been trying unsuccessfully to get the sound to work on my IBM 
Thinkpad 600X with FC4.  Sound did work on FC3.  an lsmod shows the 
following sound related devices loaded: (lsmod | grep snd)

snd_cs46xx             93097  1
gameport               18633  2 snd_cs46xx
snd_rawmidi            30305  1 snd_cs46xx
snd_ac97_codec         75961  1 snd_cs46xx
snd_seq_dummy           3653  0
snd_seq_oss            37057  0
snd_seq_midi_event      9153  1 snd_seq_oss
snd_seq                62289  5 snd_seq_dummy,snd_seq_oss,snd_seq_midi_event
snd_seq_device          8781  4 
snd_rawmidi,snd_seq_dummy,snd_seq_oss,snd_seq
snd_pcm_oss            51185  0
snd_mixer_oss          17857  2 snd_pcm_oss
snd_pcm               100169  3 snd_cs46xx,snd_ac97_codec,snd_pcm_oss
snd_timer              33605  2 snd_seq,snd_pcm
snd                    57157  10 
snd_cs46xx,snd_rawmidi,snd_ac97_codec,snd_seq_oss,snd_seq,snd_seq_device,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer
soundcore              10913  2 snd
snd_page_alloc          9669  2 snd_cs46xx,snd_pcm

I'm sure it something stupid that needs to be done but I have hit a dead 
end.  Suggestions??

Thanks..
Jeff
