One of the few complaints I had about the EVO was that the media volume was too quiet when listening through headphones. I flashed EvolutionX to try out 2.2 today and the volume is noticeably louder. For example, I only have to turn my car stereo up to 20 instead of 30 when hooked up through the AUX input now. I have no idea if it was 2.2 that increased the volume and sound quality or if something was just screwed up in my previous ROM. Maybe someone else can try it out to see.
