kikendo, try one of the attached mixers. They are from older driver packages for ISA ESS cards, but they work fine with some later PCI ESS chips.

Thanks so much for that! I will give it a try.
I noticed I am running into some more issues with this, like the synth volume is always WAY TOO LOW compared to wave. I wonder if it's related to the mixer app I was using.

Been a while but I tried these and they don’t work with my particular hardware.

I really need this because none of the mixers I tried work, I need to be able to enable and set the volume of the line in input!

Hopefully someone has the install disks for this card?

Bringing this back from the dead.

Anybody know of a DOS mixer for the Allegro that works?

I have an original XWave Driver CD that has the Allegro driver install and it doesn't have a DOS mixer.

Maybe the Diamond Sonic Impact S100 included one? Maybe some other card?

Edit:
I've looked through all the different driver versions and not even the earliest ones have a DOS mixer or volume control. Hrmmmm.

Edit 2:
I found the actual datasheet for the Allegro. Guess I might need to write a mixer myself. Looks like it shouldn't be too difficult.
Another interesting thing is that the Allegro has the built-in ability to have a hardware implementation for a volume control using momentary switches.

Any Sound Blaster PRO-compatible mixer will work. Here is a free one with source code:

The issue that I have run into is that these mixers don't work for FM, at least not on my Maestro-2E. A workaround is to use a MAESTRO.COM from version 2.11, which has a louder default volume.
