We made a mistake that has caused a fair bit of trouble the last couple of days, and I want to apologize.
We pushed build 189 to stable before we had received enough feedback to find a serious problem.
I believe it only affects people who have DAC's that need input at 24 bits. Though this is probably a small minority by percentage, it's still a large number of people.
To compound this mistake, we did it just before a long weekend, so we will be a day slower in correcting it.
I'm very sorry.
If you have had the problem, you can try setting the bitdepth manually. It's in Audio options in the second section, called "Output Mode Settings".
If that doesn't work, download and install this build:

We should have a fix for this by mid week.
