2.4.19 MAESTRO sound /dev/dsp3 broken (luxury problem)

2.4.19 MAESTRO sound /dev/dsp3 broken (luxury problem)

[Voluspa]

The fourth channel, aka /dev/dsp3, of the MAESTRO sound driver is broken (yeah, sob, sob) in 2.4.19 and -ac1. Last working that I've used, compiled as a module, was 2.4.19-pre10-ac1. The "sound" now coming out of that channel is a cry from the wilderness (confirmed with RealOne Player and gqmpeg and xine and...)

First three channels are all A OK.

Machine is a Compaq Presario 5640 (PII 400) with 128 meg mem. Builtin sound chip.

Can you try and find out exactly which kernel it broke at. The only
maestro change Im aware of was in rc1-ac7 and wouldn't have that affect
in any way I can imagine..

I remember reports from the depths of time that dsp3 didn't work.  I
wonder if there is some generation of chip that has a faulty set of high
apus.

The embarrasing thing is, I can't boot back to a working kernel. Having completed a marathon compilation I discover that it doesn't work even where it used to. Almost as if something physical has been blown to smithereens.

I'm not (overly) crazy. It _did_ work in 2.4.19-pre10-ac1+preempt. RealOne Player was bound through the environment variable AUDIO=/dev/dsp3 and gqmpeg had been configured to use /dev/dsp2.

Btw, what I called 'a cry from the wilderness' is heavily distorted audio, at a volume about twice as high as the working channels are set to (which practically means maximum...)

You won't hear from me again unless a miracle happens...
