|I think you've explained the sound admirably. Reminds me of Daleks but that might |
mean nothing unless you are from the UK. Here's one (they are not friendly):
Some good ideas at #5, also wonder if it gets any better if you reduce volume as an overload is possible (waveforms getting squared - peak clipping).
The "intermittent" and "slow downs" leave me even more baffled. Software, including drivers, isn't usually intermittent although it might be influenced by other programs.
I had vague thoughts about the sound buffer being "drip fed" and causing slow downs but didn't really get anywhere.
Generally the symptoms makes me think "hardware" but that's about as far as I got.
Will keep thinking but don't hold your breath LOL.
Always pop back and let us know the outcome - thanks
