Get anywhere with this yet?

I can't even get a MDSP2780 (765D) working in Windows 98SE. The limited BIOS shows on the test page as "DSP" available, "audio" unavailable (I assume this is normal). In Windows I've tried to "add new hardware", and no non-pnp devices are found. I forced WIndows 98 Mwave drivers on an "unknown device" in the device manager, and then it seems to get 2 of the 3 expected resource allocations (I/O 4E30-4E3F, DMA 07, but IRQ 10 instead of 9 or 15). The Thinkpad Configuration program I installed doesn't show a "DSP" option per a page I found referencing setting the wave audio working, but the configuration program's "audio" page says that the device doesn't exist. It shows up in there under the Allocated Resources View, with the driver name I force-loaded onto "unknown device" earlier. I've tried drivers IBM Thinkpad Wave Device and Aptiva Modem Wave Device, which seem to be the same thing, but still no sound. I also tried the 3-disk MWave driver, selecting the appropriate addresses, but I cannot select IRQ 10 using that driver installer. The device manager won't let me change it off IRQ10 (I assume it's hard-set there, being non-pnp).

I have no clue where to go from here in getting any audio working in Windows 98SE. I didn't have luck in Windows 95 OSR2 either. Lots of breaking things, and re-imaging my CF card back to a clean slate.

Where did you guys find Mwave drivers? I'm currently restoring an Aptiva model 2176 and I can't find Mwave drivers anywhere, just broken links. I currently have Win98 installed and the Mwave card isn't even detected as a ! in device manager.

I just uploaded the disks from the IBM ACE (Mwave) sold by Best Data to vogonsdrivers.com:
http://www.vogonsdrivers.com/getfile.php?fileid=1823

Here is a Google Drive link to all of the other MWave installers, etc. I have collected over the last few years.

The CD on archive.org linked above includes the SDK.

I found an interesting review of an MWave based card, the Office F/X by Spectrum Signal Processing. According to the article, there were two versions, the original version requiring a protected mode driver to emulate the SoundBlaster hardware registers, while the second gen emulates them in hardware.

Sound Blasting
Perhaps the most anticipated improvement in the Mwave second generation DSPs has been the SoundBlaster support through hardware. The first generation of Mwave chips relied on a protected mode driver to emulate the SoundBlaster's hardware registers. The second generation improves on this by emulating the registers in hardware. With the old protected mode driver, many SoundBlaster applications would not work. Native DOS support was not available which further limited the number of applications that could be used. The new approach fixes all this. A native DOS driver is provided that takes 2K worth of memory (and it does load into UMBs).

I bet this is why people have issues with the drivers.. because they are trying to use the wrong one. Now I need to check all the MWave cards I have and see if I have both Gen1 and Gen2.

I also found some more MWave drivers today that I am pretty sure I didn't have before.

Also check out this guy's main MWave page. He also has some custom code he made for the MWave cards - time to see what I can find in the links:

Much detail on IBM historical hardware and software has been unearthed from mirrors of the IBM PCCBBS (Personal Computer BBS), such as:

and incorporated into the primary "MCA Mafia" website (mainly MicroChannel Architecture bus related):

I believe that what you refer to as the "Dolphin" card IBM named the Waverunner ISA (there is an MCA bus version too), but there was also the Windsurfer ISA too (as well as MCA):

Which driver should I install?
The mixer doesn't work at all.

Did you ever get it to work in the end?

I'm reviving this topic as there seems to be no more recent MWave topic at all, and this has been the most extensive and helpful so far...

I got my dream 1996 Aptiva a while back and had great fun restoring it.
Thanks to this topic I managed to get my original MWave Dolphin card working well using the 20D Drivers from Cyclone3D's Google Drive.
Carefully following the instructions, it was a little unusual to do but actually worked straight away... (With this driver set at least, I failed miserably with other drivers first as well)
But it basically works together with W95's standard mixer since the hardware was installed.

My problem is however... Because I'm not an expert, and so I have no idea if this is a software or hardware fault...
Everything on my MWave card works surprisingly well... Except my CD-Audio input...
The same CD Drive with the same CD audio cable have worked on a Soundblaster 32 that I had in there for a while... So it's not those two...

Both playing an audio CD through windows, as well as CD Audio in games doesn't work at all...
However, CD's are recognized and played... Winamp will even get it's EQ VU's dancing on it...

What can be the problem here? Can this be a software thing or is it a PCB level problem that needs attention?

No, I sold it.
