Anyone have any idea why I would get random snaps/crackles/pops that, once they start, will get more and more violent until the sound out of one channel will be completely distorted? It will continue when I stop and start playing from that channel. If I switch channels, play something, then go back, it all goes away for a while.

It isn't a big deal as I can just cancel measurements and switch, but it is a frustration.

PC. windows 10 using asio4all. Output is through hdmi on my GTX970 to a Marantz 5010 with the latest hd audio drivers for installed on the cpu. Near 0 cpu load throughout.

You may want to try increasing the buffer size in ASIO4ALL if it is set to a low value.

It is set to 1024 samples.

That's not the problem then. I suspected not as mine just drops out for an instant if the buffer is too low. I might try a different HDMI cable also just to rule that out. If the GTX970 came with it's own ASIO driver I would use that instead of ASIO4ALL. [I have an audio interface that works fine on its ASIO driver, but not with ASIO4ALL.]

Just ruling out easy things - I have no good ideas for your issue.

”Play something” as in a different signal source apart from REW?

One possibility is relay contacts that have a bit of corrosion.

?Play something? as in a different signal source apart from REW?

Anything in REW. As soon as another channel produces any sound the original will be fine again.

HDMI. Not possible.
