I could do just that, but for how long?  Eventually, older version(s)
of skype could/would break and I will then be forced to upgrade.

I've switched to PA and I'm now rebuilding umpteen packages inc.
firefox and chromium!  O_o

The switch was mostly successful, except for:

After a reboot all worked fine and the pulseaudio migration appeared
to be uneventful.  The morning after things went sideways.  The HDMI
sound device was selected as the default audio and not analogue sound
was available.  For some reason the default beep was loud enough to
wake up the neighbours!  PCM, headphones and other controls had
disappeared and some new monitor-* controls were available.

This was fixed by adding:

load-module module-alsa-sink device=hw:0,0
load-module module-alsa-source device=hw:1,0

in /etc/pulse/default.pa

I have not yet tried the microphone in Skype to see if the above combo
is correct.  This is what aplay and arecord show:

The other thing that puzzled me was that the second jack for the
headphones is muted every time I re/start an application and the
volume setting is zeroed - e.g.

I start mplayer - no sound.
I unmute the second headphone jack and raise the volume setting - sound is back.
I stop and then start again mplayer - no sound.
I unmute the second headphone jack - sound is back.

and so on.  I cannot understand why the second jack is muted.  The
first jack stays unmuted in each case.
