Thanks Phil

This is one of those problems I had ages ago and never fixed, so I found
a work around that does ok. 

Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller
(rev 03)

ALC883 Analogue ALSA device is involved somewhere along the line.

I've tried lots of options in the /etc/modprobe.d/alsa-base

Here's the list:
#options snd-hda-intel model=laptop
#options snd-hda-intel model=basic
#try a fix - use last in list for headphones but no speakers
#options snd-hda-intel model=3stack-dig
#options snd-hda-intel model=laptop-eapd
#options snd-hda-intel model=6stack-dig position_fix=1
options snd-hda-intel index=0 position_fix=1 single_cmd=1
model=laptop-eapd

I'm using the last one at the moment and that gives me muted speakers,
but the headphone works.

At the time there was lots advice about rebuilding ALSA, but I wasn't
going to do that. What I should do is try a live CD of 8.04 as I'm due
to do that upgrade anyway....

For the record the Laptop's a 64 bit dual core Intel job from novatech
in Portsmouth. Richard Bruce sourced it for me specifically as  Linux
Lap top, and apart from this one minor issue it's been great! I've got
the spec somewhere!

I wouldn't want people to spend time looking for the correct sound
option - I reckon I would have found it by now. It was really just if
there was a way to restart sound without a reboot.

Thanks
David
