Picked up an Orange Monte Carlo (UK) a few days back and got straight into modding it. On stock, pre-modding, the sound was fine. Not deafening, but plenty loud enough. I then went through the whole rooting business and decided to flash CM 7.2 RC3. Everything went well and I now had 200 more options to play with. Only problem being that the overall sound was lower. First I noticed in a phone call when I had to use the (loud)speaker just so I could (barely) hear the person, then it was the same with the (several different) media and music players. It sounds like the volume is capped at ~50% of the stock level. Yes I could bump it up a bit by using the DSP, but it was still not ideal as that seemed to be artificial and caused some distortion.
So I then alternately went through 3 CM-based ROMs (CM 7.2, CM9, Ice Armor 3), and 3 stock-based ones (Skatie, Elitemovil, Atomic). All the CM ROMs have the same crippled volume levels, while the stock-based ones all sound loud and clear. I even went back to the OUK stock ROM and it was fine.
Is this to do with something CM changes that causes the volume to dip, or is it just a coincidence? Ideally I'd like to stick on CM9 as it's ICS, but not while the sound is this low.
I did try a few volume-increasing apps but they only made it a bit louder (and a bit distorted), still not up to stock levels.
Any ideas? Cheers.
