Low headphone volume after Marshmallow update.

[Erik Johnson3]

When playing Google music all access volume stops getting louder after half way. Only music App that does this. Power Amp is just fine. It is so disappointing I am going to cancel my subscription. I do not want to buy a amplifier, but I might have to. Any one else with this problem?

Try clearing the data from the app to reset it. See if that fixes it.
