Hi, all
I'm trying to set up the Terratec in a mATX system with Tualatin and a single ISA slot. The motherboard is Chaintech 6VIA5T, using VIA VT82C694T (Apollo Pro 133T).
The goal is to switch between EWS's own Dream chip, a Yamaha DB50XG connected to the front panel's Waveblaster header and a Roland SC-55 connected to MIDI-2. So both devices are on MIDI-2 effectively, to DOS games both Yamaha and Roland are at 330h while Dream is at 300h, and I can switch between Roland and Yamaha by changing mixer settings.
For tests I'm using MIDI files under Windows media player and also DOS games run in Windows DOS box. There are two problems currently:
1) Sometimes the DB50XG starts to give out "garbled" sound everywhere: it's like it's playing piano instead of drums. Sometimes I can fix it with resetting the EPROM, but after a while it goes back to sounding buggy. I assume it has something to do with switching inputs in the mixer, but I can't reproduce it.
2) So far I've only been able to achieve full functionality in Descent using Windows Sound System mode. I've been able to switch between Dream, Roland and Yamaha (well, that is, when Yamaha works at all). However in Doom I get absolutely no sound even if Roland does show notes being played on its display. I assume it's the SB Pro mute bug, but I can't find any info on how to fix it under Win98, not real DOS. I'm constantly checking Control Panel and ProMIX, but there are no muted channels as far as I can see.
I'm using drivers version 3.1, apps version D and ProMix from studio4all.
The setup in EEPROM is this:
WSS I/O 534
WSS IRQ 5
WSS Play DMA 1
WSS Record DMA 0
FM I/o 388
SB Pro I/O 220
Gameport I/O 201
MIDI 1 300h, IRQ7
MIDI 2 330h, IRQ9
Dig control I/O — PNP
The onboard audio of the motherboard is disabled, so are COM1, COM2 and LPT. Other than the soundcard there is only a Voodoo 5 videocard and a 3COM NIC installed. The revision of EWS64 is 1.2 with stock 4MB memory module installed.
What am I missing?
