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.
