Hi all,

I've got 'issues' with audio, using 1.5Y sources dated Sept. 17.  I'm just
now trying to get audio working on my PWS 500a; I haven't tried with any
other releases.  I have an identical situation to a post from Feb. 2000
regarding a PWS 433a, described at
http://mail-index.netbsd.org/port-alpha/2000/02/28/0001.html .

sb0 at isa0 port 0x220-0x237 irq 5 drq 1: dsp v3.01
audio0 at sb0: half duplex, mmap, independent
opl0 at sb0: model OPL3
midi0 at opl0: SB Yamaha OPL3

Trying to cat or play to /dev/sound[0] or /dev/audio[0] fails.  The
speakers 'click' upon driver init, but only the keyboard beep (spkr0) ever
comes through the speakers.

I pulled up the more appropriate MI ESS 1888 driver into my kernel config;
it looks like this:

ess0 at isa0 port 0x220-0x22f irq 5 drq 1 drq2 5
ess0: ESS Technology ES1888 [version 0x688b]
ess0: audio1 interrupting at irq 5
ess0: audio2 polled
audio0 at ess0: full duplex, mmap, independent
opl0 at ess0: model OPL3
midi0 at opl0: ESS Yamaha OPL3

I've tried DMA channels 1 and 3 for both ess0 and sb0 drivers.

There might be a couple send-pr's here.  Is anyone using their audio okay
with recent code on a Miata?  Secondly, are there any historical problems
or issues with the ess device on the Alpha, or can we add it to the ALPHA /
GENERIC configs?

Thanks,
David Hopper
