Hello Daid,

Thanks for your reply.

After my post I knuckled down and worked systematically through the
model= options for ALC883/888 and ALC882/885, having gleaned from the
internet that these are most similar to the 889A.  The possible choices
are listed in /usr/src/linux/Documentation/alsa/HD-Audio-Models.txt.
Several choices produced sound, but only this (for ALC882/885):

options snd-hda-intel model=mbp3

in /etc/modprobe.d/alsa.conf, followed by running update-modules,

produces sound and turns off the speakers when the headphones are
plugged in.

This was one of the options I tried before posting, having found it
using google, but it did not work.  I _think_ I made the mistake of
rerunning alsaconf after editing /etc/modprobe.d/alsa.conf, which of
course erased my edit!  Dumb.

Best wishes,
Roger
