All of a sudden - low sound

[rdyornot]

Hopefully someone can help me out on this one - sound has been fine on my MBP until yesterday, now at max volume it's become hard to hear.

I have a cinema display, and when thats connected the volume is now very low also, so I'm assuming it's a software problem, but darned if I can find it.

I've checked the sound settings, and audio midi (just in case) but thats all ok. I haven't installed anything or changed any settings in the last day or so that I can think of, does anyone have any suggestions?

For what it’s worth (hello, googlers): I’m running High Sierra (macOS 10.13.5), and what caused the same behavior for me was Safari, for some reason. Quitting it reset the volume to its original level.

Thank you so much wrongtrousers, thanks to your comment I quit Safari and the sound went back to normal again

Many thanks!!

This worked for me on Mojave as well.
