I recently installed Asio4all (v 2.9) to use for live recording/playback in FL studio (XXL 8.0.0). I've been using a USB microphone to record.
At first everything works fine. The audio starts out clear with no clicks/pops/underruns. After about 30 seconds or so, there are a few minor clicks and a quiet, repetitive chopper sound any time I speak into the mic. As time goes on it gets worse and worse. After some time (varies with different settings), the chopper sound is significantly loud any time I speak. After several minutes, playback is almost completely distorted by the chopper sound.
I can temporarily stop the problem by messing around with audio settings (i.e. if I change any options in the asio4all panel, change any input/output settings, etc.) This just restarts the process though. Audio sounds good for a few seconds or minutes, then gets progressively worse and worse...
What I've tried: - Re-installing Asio4all (I recently updated to the latest version) - Every combination of settings in the asio4all panel - Max values for Buffer size, latency compensation.. etc. - Checking 'allow pull mode (waveRT)', 'always resample 44.1khz <-> 48khz', and 'force WDM driver to 16bit'
Some of these things worked temporarily, but the sound ALWAYS comes back. I have the same issue on both my desktop (running Vista 32-bit) and laptop (running Vista 64-bit).
I've seen other people encounter the same or similar problems, but their solutions haven't worked for me. PLEEEEEEASE help me fix this, it's driving me insane!!!!! I'm willing to re-try any solutions, so even if I've already tried it.. feel free to suggest it again.
Thanks!

Have you found a way to rid the problem yet? I have it too and I've got nothing.

By maximizing all buffer sizes I've made it so there is about 10-15 minutes of clean recording time before the crackling starts up. It's not a solution, but it does allow for a whole song to be recorded without any problems.
Still, it would be nice to have a solution rather than a work-around.

I'm wondering if by chance you have any inputs or outputs disabled... I was having the same issue with my old Audigy, but only in Mu.Lab--eventually the audio would glitch out into something that sounded like severe bit crushing, and the only way to get it back to normal was to close out the program and start it up again. But then the other night I was mixing in Reaper, and wanted to test my mix on my stereo system, so I enabled my onboard realtek output in the asio4all dialogue (just the output) and lo and behold the same weirdness started happening on the realtek. It was only when I enabled the Realtek's input as well that the problem went away; and that I realized was the difference between my setup in Reaper/VSTHost and my setup in Mu.Lab--I use Reaper and VSTHost for recording input, so obviously I have the Audigy inputs enabled in those programs--but I didn't have it enabled for Mu.Lab. As soon as I enabled the Audigy input in Mu.Lab's ASIO4all dialogue, the glitchout problem disappeared completely. I don't know if it will help your situation any, but it's worth a try...

Unfortunately, this ...shall I say: "sounds"... like you operate two or more devices in parallel whose sample clocks are not synchronized. The ballpark order of magnitude (couple minutes) after which this has an audible impact and the dependency on buffer size also support this conclusion.

Is there any way to synchronize the devices? Unfortunately, this is not something you can do in software alone. On the other hand, I'm quite surprised that this problem should show up in your particular configuration. I assume your USB mic operates as a synchronous USB audio class device (most inexpensive USB audio things do). If that is the case, its reference clock is the 48MHz clock of the USB controller on your mainboard (you are not, per chance, using a plug in USB controller card for that?). Now, the USB controller on your mainboard should be driven by the same clock synthesizer chip that also drives the reference sample clock of your embedded HD audio CODEC. Thus, unless one of the above underlying assumptions is wrong, this clock deviation is quite a mystery. Just in case, please try the followinf test build: www.asio4all.com/debug/ASIO4ALL_2_A_English.exeand see if this makes any difference (load defaults after installing and start setting it up from there)

After installing the test build, restoring defaults, and activating the right WDM devices, it seems like the sound is completely gone. It's been about 15 minutes and there's no crackle! I'll test it on my laptop later.
THANK YOU SO MUCH! ;D

Unfortunately the test build didn't fix the problem on my laptop... Any other suggestions?

I had the same problem some time ago since I use ASIO4ALL to merge sounds from different sources. I solved the issue synchronizing my equipment through their S/PDIF interface. I am still looking for a software solution, though.

Wow, I have the same exact issue!
Glad I am not alone!
Please Michael, I hope there is a fix. It seems like just simply opening/closing ASIO4ALL panel solves the noises until they random come back later.
I tested the build A file you posted, it did not solve the issue. I still get bad static almost everytime I insert a VST into FL Studio.
Please respond with any updates on the situation.
EDIT: I checked off EVERY Box (activated) in asio4all ontop of DEFAULT settings and so far the random issue has gone away and have been recording for nearly 30 minutes. Almost no latency as well. Will keep you posted! (using build A of asio4all)

The horrible crackling returns regardless. Also, it seems I get some minor pops once in a while if I have all the settings enabled anyway. lose lose situation. Where is the help? Anybody out there?

This isn't an ASIO issue. I don't know what causes the problem, but I get it too. I'm using a 1/4 inch to USB guitar chord, and I was getting the crackling before I even installed ASIO on both Amplitube and Guitar Rig 3. The crackling shows up, bothers me for about 5 minutes, then goes away. Then it shows up again 5-10 minutes later. Nothing I've done has fixed it, whether it's changing ASIO settings or my sound settings in windows. It's horrible and needs to be fixed.

Hey, I fixed it. I just turned on Hardware Buffering for my usb guitar cable in the asio menu and set it at 10ms. Works perfectly!
