Thanks for your help in advance.

Hi Wolfgang. If the laptops sound is ok with Ubuntu, that's a good start. Was 
that a live Ubuntu cd, or Ubuntu installed on the laptop. I ask because 
sometimes live cd's are better at setting things up, than installed distro's.

  

It was Ubuntu installed on the laptop. Unbuntu 7.x

Back to F8, which I've recently installed. F8 now has pulseaudio installed, 
and I've seen a lot of problems with it on the Fedora list. When I tried to 
play a cdrom, I got a permission denied, so removed a couple of pulseaudio 
packages that resolved the problem, as below.
yum remove kde-settings-pulseaudio alsa-plugins-pulseaudio

  

I had the same behavior in FC6/FC7, for pulse audio is not the root cause I believe.
What puzzles me, that it seems to be a non-systematic pattern. I sometimes works, sometimes not. Right now it is working and I am listening to music.

Now that may not be your problem, but it's worth keeping in mind.

I also have problems with my usb midi keyboard, which uses snd-usb-audio. More 
often than not when booting up snd-usb-audio is set as sound card 0, and the 
actual soundcard (especially if /etc/modprobe.conf lists it as card 0 , and 
indexed as 0) ends up not being loaded at all.

Setting indexing options for the various cards resolves this problem. With 
that in mind, would you post the contents of /etc/modprobe.conf, and also the 
output of /sbin/lsusb. The output of cat /proc/asound/cards may be usefull as 
well , for when the sound is working , and not working.

  

/etc/modprobe.conf
alias eth0 8139too
alias scsi_hostadapter libata
alias scsi_hostadapter1 ata_piix
alias eth1 ipw2200
alias snd-card-0 snd-intel8x0
options snd-card-0 index=0
options snd-intel8x0 index=0


cat /proc/asound/cards
 0 [I82801DBICH4   ]: ICH4 - Intel 82801DB-ICH4
                      Intel 82801DB-ICH4 with VIA1612A at irq 9

Will you download and run this script below. It provides a lot of info about 
the sound setup on your distro. You will have to make it executable before 
running it. It will send the output to pastebin. Paste the link to the 
pastebin file in your reply.

I'm not too clued up on a lot of Alsa problems, but try to offer suggestions 
where I can.
