Volume hack possible?

I've asked in the aicp thread but no answer so far, so maybe here i'll ask again:

Is it possible to increase the in call and speakerphone volumes for lollipop roms?

Have googled it but seems like all the solutions are for kk roms.

Hope its possible, The aicp rom is working great but the volume is a bit of a deal breaker for my dad.. Poor hearing i'm afraid.
