I've recently installed some audio apps, (Boom, Audio Hijack Pro, Piezo) and now I have this annoying echo that seems to be caused by some audio device.
I came to that conclusion after hooking up my headphones and hearing everything normally (it's also normal when sound comes from internal speakers)
Help, please.
MacBook Pro, OS X Mavericks (10.9.2)
You might be able to troubleshoot by device in System Preferences > Sound > Output
I'm so embarrassed right now, I just noticed that I accidentaly pressed the "surround" button on my speakers.
I honestly didn't noticed it before and it has been like two days.
Thanks a lot,though, for your speedy reply.
You're welcome 🙂
Where is the surround button that you are talking about?
I got the same problem. Can't fix it.
How to remove annoying system-wide echo?
