>Description:
	Audio never worked on Alpha PWS (Miata) machines.
	Then around 10 januari I found a patch that made it work.
	I tried to find the originator to confirm it to hir but I must
	have lost the original message; I can't find it anymore.
	There is no sign of a similar patch in gnats that I can find,
	hence this pr to keep the information.

	This patches the audio so that it works via the ess device;
	the audio is afaik also supposed to work as a soundblaster but
	that never worked for me either.
>How-To-Repeat:
	Try to use sound. Hear silence and see strange messages in syslog.
>Fix:

Like I said, not my patch, I can't give credit to whom it is due.
This patch is for the 2.0 branch, I notice that in -current there are
some changes in essreg.h but it doesn't incorporate this difference.

(in fact it seems that ESS_USE_AUDIO1(model) is after the patch now true
for all supported ess models??)
