My 14" 2021 M1 MBP is about a year old. I used to be able to keep the volume at 3 bars and could hear videos fine. Now, I'm having to put it up to about 75% to get the same volume. It's running Ventura 13.2.1 and the timing of the volume change seems to roughly corresponds with my upgrade to Ventura from Monterey. I've searched but not come up with any similar issues. Any idea?
