no sound after update

[xidragon11]

i just got my xperia sp like a week ago...when i connected it to my pc the sony companion showed an update so i updated my phone. But ever since the update there is no sound in my phone as well as it is unable to play songs or videos or even record audio...it gives the message UNFORTUNATELY SOUND ENHANCEMENTS HAVE STOPPED WORKING.....please help what should i do...i am kind of a noob at all this as it's my first android phone

[xidragon11]

even doing a factory reset did not solve the problem....what else can i try....should i get the handset replaced as it is only a few days old???

that my friend is another option and would advice you take it as it might be a faulty hardware issue. back up all you have now and get it replaced and update new phone to latest software . cheers 

[xidragon11]

i dunno if it's a hardware issue bcoz everything was working fine till i updated it

[dm84]

have you tried a factory reset and repaired with pc companion or SUS ?

[xidragon11]

yes i've tried both...i tried factory reset as well as repair with SUS... it's now updated  to 12.0.a.2.254

everything else is working fine except for the sound and playing video....

[dm84]

DO YOU HAVE  previous  backed up data if yes revert to it see if the sound comes back 

[xidragon11]

did that as well no luck there problem is it's not even recording voice can't hear anything when someone calls or i call someone...

Then I'm afraid you'll have to go exchange it for a new one to have peace of mind sadly that's the only other option I see
