How to solve speaker volume problem in mini pro?

[#1]

I purachased Xperia Mini Pro a few days back. For the first 3-4 days the speaker sound was loud and I was happy about it. But suddently the speaker volume level has decreased and now it is very subdeud even with full volume. I've chacked xLOUD and it is turned on.

Can anybody suggest what's wrong with my phone?

Also backup EVERYTHING then use either PC Companion or Update Service to repair your phone

Update Service

another thing I would try is to download Quick Settings

click on volume and turn up all the volumes, that might solve your problem

Applied all the three suggestions but none of those solved my problem.

Still volume level is low.
