For anyone having this issue, I found a fix.
Under audio, my encode mode was AAC and my sampling frequency was 32000. It worked fine this way for years in DMSS until a few updates ago. If you set the sampling frequency to 64000, it fixes the problem.
So set the following under audio in the cameras web interface:
encode mode to AAC
Sampling frequency to 64000
And needless to say, make sure noise filter is disabled.
