I have the Multimedia 16 ABI (AZT-2316), this is one of the best SBPro2 clones around, has a very clean sounding coded, even better than the original SBPro2.
It has original OPL3, bug free MPU-401, Wavetable, and excellent drivers, definitely a good choice for a retro PC,,, but it lacks a lowpass filter over the PCM sounds, but so does the Audician 32 Plus.
BUT, it has an issue in my system (P200 MMX) that some games freeze, like Prince of Persia and Supaplex, these games use singlce-cycle DMA.
Its self noise is very quiet, but you have to set the mixer properly and use a correct line load (10k).
- Code: Select all
volset.exe /x:16 /v:16 /f:16 /m:0 /c:0 /l:0 /m:0 /r:l
No ISA card that I know of has headphone output, the output impedance is build for line inputs (10k load) or Speaker (8ohm load but not headphones).
I don't know where the 'trend' came from to plugging headphones into the line-out or speaker-out of a vintage ISA card, but it is definitely wrong and will sound wrong.
The right way is to use a headphone amplifier or mixer with dedicated headphone output.
Anyway, I've had a chance to test the AZT-2316 based card again, and it sounds good even without a lowpass filter.
But as I stated earlier, it has some issues with single-cycle DMA mode, on my machine at least.

Please move this thread to the Marvin->Sound board.

On the newer AZT2316 based Aztech card I see a TDA1517P which should give a 5W 0.5% THD into 4ohm, half the power for 8 ohm etc..
For a typical 16ohm headphone max power will be around 1W , that is plenty to drive the headphone into distortion and your ears to bleed.
Most portable headphones rated around 100db SPL per 1mW so the on-board amplifier should be plenty.
But, I will not trust the amplifier IC to put out frequency response or self noise characteristics similar to the line-out with a proper 10k load.
One thing is definitely sure, 16ohm headphone should not be plugged into the line-out jack because its output op-amps provide no current and will distort the waveform and/or frequency response and who knows what else pretty much immediately.
I can run a test with 8 ohm load power resistor and tap that through a 1K resistor into my test equipment to see how the amplifier behaves, but meh...

Which Win 3.11 / Dos driver is it for the Packard Bell ISA Sound Card 030056 / Aztech one?
It is: -FCC-ID I38-MMSN837
I can't find a match. Please can someone help?
Thanks,
Andrew.

You'll know with certainty if you're okay with peeling away the stickers on the chips.
You should be able to use drivers from any of the third gen cards. Try the ones here:
ftp://ftp.aztech.com/support/DOWNLOAD/sg/P16II/
You need P16IIB-1.ZIP and P16IIB-2.ZIP for the contents of the driver disks. OS specific drivers are in the 2316xxxxx.ZIP files.

I've tried the drivers and nothing..
On the drivers that Jesolo provided, there was no 'hardware not detected' message but no sound either.
I give up with that card.
I had a replacement ESS ES186F ISA Sound card, but when this is installed, the mouse driver won't find the mouse.
So I'll take a gamble with another ISA sound card on EBay.
This is for my 'new' 'old' Dell Dimension P90.
