I'm getting some intermittent pops in the sound whenever the buffer length is reached. Allow me to explain. The longer I set the buffer length (64 ms, 96 ms, etc.), the longer between sound hiccups. They never do go away, however.

Is there a fix for this?

I know there was an echo buffer fix not too long ago - try the most recent test build here: http://download.sessionclan.de/overfien ... 122011.zip

Ok, I tried it. No difference, still having sound hiccups.

Have you enabled sound sync? Try lowering the input rate.

To clarify OV2's comment a little, try going into Sound Settings and bring the Input Rate down by 100 or so, and make sure the 'Synchronize with sound core' option is checked.

Tried it, no effect. Shields are down to 57%!

Does this have anything to do with it being the 32 bit version of the program that I'm running on my desktop? Because I don't get these hiccups when I run the 64 bit version on my laptop.

specs?

also, have you tried killing bg processes to see if something else is interfering?

It's a Gateway 842GM, and I just got this guy installed on it today.

I wouldn't know which processes to start with, honestly.

Try the integrated sound card (it has one built in), and if the crackling goes away, you know what the problem was. You should be able to switch on the integrated audio in the BIOS.

Holy shit. I NEVER in a million years would have guessed that having the Output Image Processing set to "TV Mode" was what was causing the problem. I turned it to "None" and the problem went away completely.

This issue is resolved...except that I like TV Mode...oh well.

EDIT 1: Further info.

There were still traces of sound popping until I disabled the "Hi Resolution Support" and "Blend Hi Res Images" options as well. If I had to make a caveman-like guess, I'd say the Hi Res engine is bumping up against the sound emulation...

This is in the Win32 version of the program, mind you.

EDIT 2: Even further info.

After switching the Output Method to OpenGL (which I can now do with no video problems, due to replacing my graphics card), the Output Image Processing and Hi Res options can be re-enabled with no further sound issues.

Swish!

Ahhh, that explains a lot.

What it sounds like to me is that your computer can't keep up normal emulation speed while using the filters without OpenGL picking up the slack. Then when your sound buffer runs out and the system emulation hasn't quite caught up, you get a slight gap between the end of the buffer and the start of the next buffer sample.

Since the OpenGL settings let the graphics card handle some of the image processing, it gives your CPU a bit more breathing room, and voila, you're emulating at full speed.

this worked for me. running on ubuntu 14.04 with nvidia gtx 660ti and i7 3770-K 8GB

Hi! I also had a very similar hiccup. With the x64 version of Snes9X freshly unzipped, I immediately loaded a Mortal Kombat ROM, and suddenly could NOT escape the cries of what seemed to be a very agitated Geiger counter. After flailing around with a handful of settings from the Sound column, whether I was making the clicks more rapid or slowing them to a near metronome pace, I ventured into the Video column.

Nothing I did had any significant impact.
I suck.
Now, five and a half years since this thread was last alive, I humbly beseech thee -- here are my specs, please help!

Just ran into the same in SNES9X 1.60 X64, and this thread was one of the first search results, so I'm posting a little more help for anyone else looking.

On my laptop, changing to DirectDraw mode (not Direct3D or OpenGL) made a big improvement. It's a dual-GPU (Intel UHD 630 / Nvidia RTX 2070) and I've noticed anytime it decides the Intel GPU is good enough for a job that requires hardware acceleration, it performs poorly.

An even most reliable fix for me was also in the video menu: allow automatic frame skipping (at most 2). This helped with all 3 video modes, but I opted to stick with DirectDraw.

I'm able to use filters like TV Mode without issue.

It would be nice for SNES9X to somehow decouple uneven video framerates from audio stutters. None of the sound settings, including Input Rate and Synchronize with Sound Core, seemed to have any effect on this problem. I had to tackle it entirely though video settings.

I had audio crackling on my PC using it, until I changed video output to D3D, then it completely went away.
