I totally agree here... it seems like a great move in one fell swoop to be able to acquire the possibility of having both an external line in on a 3,5'' jack and at the same time an internal RGGL header to use a real analog CD input from a real CD-ROM like a real sound card!

Out of curiousity why do you need to keep removing the card to change the IRQ and DMA?

It is useful for example when you have to switch from GUS mode (a good IRQ for compatibility in GUS mode is 5) to MPU mode with IRQ 2 for the old dos games which need an IRQ mandatory = 2 to works properly:

You could use this type of switch for that.

I know that...but I don't like, from an electrical point of view, extending the IRQ line over a cable of any (even moderate) length.
Can anyone with experience with native GUS audio games tell me if they would run 100% reliably and compatible with the PicoGUS (GUS mode of course) set to IRQ 2 (instead of IRQ 5) while still maintaining DMA 3 on the PicoGUS?

Hello everybody, yesterday I observed a bizzare behaviour. My "slowest" rig is:

1. ECS P5HX-A i430HX
2. P166MMX etc...
3. PicoGUS 2.0 with jumper on irq3 dma3
4. AWE64 value

I use a modified Phils Bootmenü to select in autoexec bat between the 2 soundcards, one of which I will use in MSDOS6.22

Yesterday I configured Doom1 setup as follow
SB irq2 (no irq3 in setup) dma 3, A220

Btw: in GUS Mode the PicoGUS functions flawlessly in Doom1 with A240,i3,dma3 as SET ULTRASND

I thought "ok, I select irq2 and later change it in some .cfg file"

But nontheless after save+start game I heard music and soundfx.

How is this possible?

Another question:
When I choose in the Menü AWE64 with A240, irq7,dma1,H7, T6 and then in Doom1 the same values for SB I dont hear nomusic nofx?

Is there sth special about Doom1 v1.7 or i430HX Boards?

On my other rig Asus P5A 1.04, K6-3, PicoGUS 2.0, AWE64 value, onboard SOLO1 everything functions,setup exe accepts every one of the 3 as a SB device even with different values:

1. PicoGUS 2.0 = A220,i3,dma3
2. AWE64 = A220, i7,dma1
3. SOLO1 = A240,i5,dma0

Last but not least:

When I booted into the AWE64 and started PrinceOfPersia1setup, I configured all the value for the AWE64 but the, after starting the game I heared music only from the PicoGUS...? Pop1 ignores the AWE and chooses nontheless the PicoGUS?

Just now I am testing Doom1 in dosbox-x with sound configurations and noticed the same behaviour. SFX will work as long as base address and DMA are correct, IRQ can be set to anything. I don't know if this is universal or only happens in some sound cards. Maybe the game pulls in the IRQ from the BLASTER variable on launch automatically.

I don't think there is anything special about doom1 on i430HX, maybe there is an onboard device using one of the IRQs. I always set the IRQ and DMA used for DOS sound to "Legacy ISA" in resource assignment to avoid potential clashes.

Only one card should be able to respond on port 220 so this probably makes sense, the PicoGUS took over. If two SB cards are active they need different base addresses. So the PicoGUS, AWE64 and SOLO would need to be on 220, 240, 260 for example.

For me, since PicoGUS is the best at playing old single cycle DMA games, I have it set to IRQ7, DMA1, 220 so it works with all the old games that may be hard coded to use IRQ7 or DMA1 (er example Day of the Tentacle). I have my SB16 on IRQ5, DMA3, 260 and use it for later games that use Auto-Init DMA.
