After jumping those two pins, I am still getting the same level of hiss. Just to make sure, I took the jumpers off with the slider maxed so I can detect any changes. None unfortunately. Here's a quick video I made playing around with the mixer settings. https://youtu.be/GdcVedXM88s

CT1703-T is the noisy DAC appearing only the CT2230 (19413) and (29417) but not on the CT2290. Ah, this explains my situation. I have the CT1703-T on my 29417 revision. Same here. I also thought the chip to look out for was the CT1745 - but I think you're right about the CT1703 chip. I have the …

Some questions for you guys, When the sliders are all set to zero except Master and Gain, does the card hiss? What slider produces the most hiss, besides Master and Gains? Thanks for that info. I'll be careful with that info and see if that can help. That shouldn't affect the MPU401 interface, …

MIDI is responsible both for FM (OPL) and Wavetable Return volumes. It can be that the wavetable amplifier on the SB16 is noisy or the wave table itself if you use one (unplug it to test). It also can be that the FM DAC is noisy. The MIDI volume dial on my CT2230 has no effect on the hiss level, …

Hmm... SB16 is the only card now. I went to the mixer and as I was messing around with the sliders I found out that when I was turning down the MIDI slider, the hiss goes away. So... it's the MIDI audio that is causing the hiss??? I didn't expect that. I'm going to turn down the MIDI slider to get …

1745-S ? it is a third variant I am not aware of, don't know if it is quiet or not. Can you please post and image your mixer settings? I have tested and found that AGC and MIC are the primary cause for noise, without them I can get 76db of SNR which is absolutely silent from a 1745A which …

Much easier and faster than using the old parallel external drive that was our FIRST foray into ZIP disks back on the old Packard Bell Windows 95 days. I even remember we chained a scanner off of that, then hooked a printer up to THAT. LOL And they all worked! Wouldn't that have been a SCSI …

I'm going to try those mixer settings. Mine has a hiss once it's initialized. But as we chatted in a different thread, mine has a different mixer chip that the 3 known variants. http://imgur.com/DmQyuxv It has a CT1745-S (note the missing "A")

fdisk/mbr always fixed this for me. In an old thread, there was still report of Operating system not found after using sys C:, then fdisk /mbr.

I did some searching and found a couple of threads in regards to this issue, but none brought up using DISKPART to fix the issue. I recently bought one myself, and found that some SD/microSD cards doesn't seem to boot even after using FDISK to clear everything out. I thought it had to do with some …

Is it an underclocked CPU? I'm just getting confused. In the BIOS it says 1664 MHz / 800 MHz and I don't know what that's supposed to mean :confused: 1664 MHz is most likely your CPU's speed. 800 MHz is most likely your FSB P4 FSB is quad-pumped, meaning the actual FSB clockrate is 200 Mhz, but …

So far, I can set the AUTOEXEC.BAT and SYSTEM.INI to force MIDI OUT to 330, but every time I reboot, the settings go back to 300. I can see DIAGNOSE.EXE /S /W=C:\WINDOWS is causing this from the output as I boot up and run through AUTOEXEC.BAT, but once I REM'd it out, it still does it! I'm on DOS …

Yes, the AWE 32/64 has the same topology as the SB16, it is basically a fancy upgraded SB16 Vibra. Why didn't you like the CT2230? The only solution to the SB16/32/64 family is a separate MPU-401 card, you have the YMF71x, use it. Also tried Mortal Kombat 2 - starts working, but as soon as you hit …

Whoa... So I have a SB AWE64 Value and it ALSO stutters when playing Duke Nukem 3D with my SC-55 ( MPU). I thought it was only a SB16 problem. What the hell, Creative/3D Realms? Also tried Mortal Kombat 2 - starts working, but as soon as you hit F1 to start, it hard locks.
