Sorry, I've got no AWE64 at hand right now. 🙁
Maybe setting the ISA bus frequency to ~7 MHz changes something.

Important info missing: when you say: "when FM sound is playing", how do you play FM sound? MIDI player, games, etc.?

Also, it seems you did not try yet without the 3COM, did you?

No I mean FM (Adlib) music! Anything else is ok. I did not try it without the 3COM, I will.

I dont think my motherboard supports changing the ISA bus frequency, or at least I haven't seen any options in my BIOS.

Is your FSB higher than normal ? (Like 75MHz for example)

Yes, I perceived the same FM issue when I tried an AWE64 gold. But I did not try to solve it. I swapped out the AWE64 gold for another soundcard. I know this does not help much.

Nope, I'm on "stock" 3 x 66 MHz for my P200 MMX.

That's interesting! Do you remember your PC configuration at the time?

E: Okay I have a breakthrough! I tried without the 3COM card, which didn't change a thing.

However I just noticed that I don't get the clicks testing FM with Sound Blaster Diagnose. Also from that point on I don't get the clicks until I reboot!

To be clear here's what I'm doing:

1. Boot
2. Test FM (wolf3d), with clicks
3. run diagnose.exe, with the Synthesized Music test, no clicks
4. Test FM (wolf3d), no clicks
5. Reboot
6. Test FM (wolf3d), with clicks
7. ....

This is a config problem, I'll investigate further 😀

Are you calling aweutil.exe in your autoexec.bat? If not, the FM part may not be resettet correctly, which may be the cause of your problem.

Yes I am. Here's my AWE64 related stuff in my autoexec,bat

1SET CTCM=C:\CTCM
2SET SOUND=C:\SB16
3SET BLASTER=A220 I5 D1 H5 P330 E620 T6
4SET MIDI=SYNTH:1 MAP:E
5C:\CTCM\CTCU /S /W=C:\WINDOWS
6C:\SB16\MIXERSET /P /Q
7C:\SB16\DIAGNOSE /S
8C:\SB16\AWEUTIL.COM /S /R:10 /C:10

I tried messing with the order of things to no avail.

Found out that running aweutil /S after the diagnose workaround brings back the clicking.

Okay so here's what I found:

In my autoexec.bat..
If I don't run AWEUTIL: no FM, of course

If I don't run AWEUTIL, but then run diagnose.exe: The card is initiated perfectly, but I have to run the program, wait for the tests, exit, ...

If I run AWEUTIL: FM with clicks

If I run AWEUTIL, then diagnose.exe: The card is reinitialized, I lose my reverb and chorus effect, but I get no clicks

I'm fine with having no chorus or reverb.

I'd have to find a way to automatically initialize the card with only diagnose.exe, is that possible?

Weird stuff. But at least there might be a solution in the line of what you are currently trying.
What if you just switch the order of these two lines, like this:?

1C:\SB16\AWEUTIL.COM /S /R:10 /C:10
2C:\SB16\DIAGNOSE /S

The system that I was using at the time was i440BX based. Either from Aopen or Gigabyte.

Same problem using that order.

I even tried moving my AWE64 block in my autoexec.bat to the end and it exhibits the same symptoms.

Fixed by updating AWEUTIL from 1.20 to 1.35 ...

Good find!

Where do you find AWEUTIL 1.35? I've got the same problem.

This link should lead you to AWE64 Gold driver section of Creative's website.

If you select "DOS" in the pull down menu at the bottom, you should be able to download s64basic.exe and ctcmbbs.exe. After you unpack and install both, you will get aweutil.com v1.36.

This is assuming you're running MS-DOS 6.22. If you're using Win9x, you will need to download 95dosapp.exe instead.
