The Audio/Volume on my iPhone 3GS has Decrease SIGNIFICANTLY After iOS 5 Update. Oddly, the volume of the ring is fine, and as lout as it used to be, and as loud as all other audio should be, but when using any 3rd party applications, the volume output is significantly less (about 40% less) than it used to be.
I am NOT the only person to experience this problem. Apparently, the issue has been around since this past summer, when iOS was still being developed / tested. There is a post about someone experiencing the same issue, here:

And before you ask .. I did a language change and reset, and I am still experiencing the SAME issue.
Any help or advice with this problem would be greatly appreciated.
In advance, thank you.
I experience the same problem whith my 3gs after ios 5 update but my volume has decreased about 50% in all applications. Audio, Ring, Games, Apps.
I restore my phone, i change language, i check my settings if it was my mistake but nothing.
I hope it will be fixed with next update.
I have a similar or related problem with iOS5/3GS and volume:
In my case I can hear nothing from the internal speakers although I can use headphones. The volume slider bar is unavailable unless I plug in headphones.
I also have similar problem with my 3GS (iOS 5.1.1 factory unlocked and not jailbroken), no audio and volume slider when I'm not using headphone.
Yesterday I bought a headphone splitter, when I used it suddenly the volume slider did not disappear anymore when I removed the headset. I'm still observing its now and hoping that it won't reoccur again.
