I got a new iPad 2 RevA, Also known as iPad 2 (2,4) , the one having the smaller A5 chip and having the excellent battery life, it was working super fine, until one day, the Loud speaker in the iPad seemed to lowered the Volume.
And no, i don't have any Volume Limits on, i have made 3 complete Restores for the iPad, i was on iOS 6.1.3 & the iPad seemed really Loud when i was on iOS 6.1.2 .
I'am now on iOS 7.0 Beta 6 & and everything is very good , just except that sound problem.
I sometimes try to enable 'mono audio' in Accessibility settings to make some songs louder.
I also have to mention that i used to mirror my iPad in full HD with the HDMi converter & i also used the AV cable, if this may help.
I'am new here & i searched everywhere on Google to solve my problem but with no success & please don't tell me to get an external speaker, i already have 6 X-minis , it's ruining the iPad's portability .
'I never dropped my iPad, i'am taking very good care of it .
Thank you very much for helping me
