I Have A MacBook Air MMGF2HN/A Model Running On MacOS Sierra 10.12,One Day I Putted My Woofer Jack Into My Mac,After That When I Plugged My Sony MDRZX110 Headphone Into The Jack,The Sound Is Coming Only From The Left Side ,I've Checked The Headphone In My iPhone And It Works Flawlessly.So Is This A Big Problem As I've Checked All The Things Like PRAM,SMC,Sound Balance Etc..Please Help Me With This
MacBook Air, macOS Sierra (10.12)
Hi There,
I have this issue too for my macbook air 2012 version.
I pretty sure there is something wrong with the mac air.
Trial#1:
Plug in headphone--> On Music --> No Sound.
Trial#2:
Flip down the screen to sleep ---> Plug in headphone --> Flip up screen awake ---> Play music --> Only left side has sound.
Trial# 3:
Was using another bigger headphone, it was working for 1-2 times, then not working anymore.
I do not know why the screen must flip down and up before headphone can work?
As such, i do not know why only one side is working eventhough i have checked both Sound stereo, Mini setup are both channel at same level, reset SCM/PRAM..etc. ALL tried but the problem yet to resolve.
I guess this is something macbook air expert can advise, i do not see it for Macbook Pro so far.
Thanks.
