Starting this morning, whenever I attempt to play a music file in a Finder window (or directly on the Desktop to preview it), the audio plays at a higher pitch and faster speed

I did a quick Google search and it appears many people have been experiencing this over the past few months

The only method I have found thus far of fixing this is to restart my Mac but, that is only tenable for so long

Anyone here experiencing this as well? If so, did you find a better fix than restarting your Mac?

Thank you
 
Hi, first of all, sorry for my bad english, I'm an audio engineer an Mac technician for recording studios with 20 years of experience and what you describe it's usually caused my a mismatch between the sample rate of the audio file being played and the audio interface. (if you play a 44.1K file at 48K it will play faster and the pitch will increase, that's nothing weird.

I would check in audio midi setup how the sample rate of the mic and the speakers are configured, you should have both at the same value and I suggest using the speakers as the clock source.

As almost everything you will reproduce would probably be at 44.1k I would start with that, but try 48k too. I use 24 for the bit depth.

if that does not work try adding an aggregate device, and put everything like in the pic attached, its in spanish but the GUI is the same
