I have an S3 with the latest updates, I noticed when I play music the volume is really low, I would have to turn up my car stereo/desktop speakers way too high to get it to sound right. I messed with the settings in Poweramp and when I went to: Settings Audio Advanced Tweaks Direct Volume Control I clicked this on and noticed a huge improvement. However, when I start playing music after shutting off Poweramp, this setting is still checked, but the volume is low again. I have to go back into the setting, uncheck it, then re-check it and the volume goes back to normal (volume increases
