I am loving this laptop and the sound is nice on these but the volume is pretty low compared to my old MacBook Pro. Is there anything I can do to make it even 10-20 percent louder?
Hmm... I have the opposite experience. The speakers can go louder than I will ever need on a laptop.
What application are you using to test the volume?
You checked system volume vs application volume?
How is the volume when you hookup external speakers / headphones?
I’m having the exact same problem with my 10th gen MBP 13” compared with the 2018 model with 4 thunderbolt ports. The max volume on the 2020 MBP is slightly less (confirmed with a decibel measuring app).
