DBM doesn't play alarm sounds anymore

Hello,

i have recently updated my DBM version to 10.1.13. and also got a few weakauras around the same time - everything works fine, except that the "sa1" alarm sound isn't played when a boss mechanic is affecting me. It does display the text, but there's no sound. My brain has been hardwired over the years to this sound, so after a while, it did led to one fatal mistake.

I couldn't find anything online, can anyone help me? DBM seems to be configured correctly as far as i can see, it's on default settings, and "sa1" should play when i stand in bad stuff for example. I can play the sound effect just fine in the DBM options.
