Jenkins CM 10.1 bug

[Guest kamango604]

Ive noticed a bug with volume lvl while playing music on headphones. Jenkins roms have pretty much average sound. But when i call someone during playing music and end call, volume gets immediately higher for about 30%. Ive noticed this on 3-4 builds, but how can i make it pernament. I dont want to dial someone everytime i want higher volume. I dont know what to relate this to, maybe kernel?
