Why is my MacBook Pro headphone output so low?
For some reason, the output on the headphone port on my MacBook Pro is suddenly very low. I have a SoundStick III connected to it and at full volume, I can barely hear anything. I got another SoundStick III that I connected to the headphone port and I had the same results, the output is very low.
I tried switching the cable that goes from the headphone port to the SoundStick but, again, same result.
It seems to have happened after a previous system update. I tried to reset the NVRAM, PRAM, and SMC but that didn't do anything.
Anyone knows what could be going on?
