Since jailbreaking my iPhone 4 with Comex' jailbreak I am experiencing volume problems while playing music both through headphones and over bluetooth. Basically, its not as loud as pre-jailbreak. I have both Sound Check and Volume Limit set to OFF in Settings and I'm finding I'm having to crank the volume right up to max in order to get sufficient volume. I'm using the same decent set of Ultimate Ears in-ear phones so that's not the issue either. I was actually thinking that the iPhone4 sound was superior to the 3GS but now I'm not so sure. Is anyone else experiencing this and is there a Cydia tweak (obviously relevant to iOS4) to sort this out?
