Merge "Fix bug 2329540 Part 2 of fix Modify the behavior of the volume computation in the APM for the MSM8K to deal with the car dock limitation where the user doesn't have access to the physical volume buttons on the side of the phone when it is docked. Docking the phone with too low a media volume would make the 3.5mm headphone jack unusable when connecting the device to a wired analog car stereo adapter. The change consists in setting a fixed volume value for the MUSIC streams played through the wired accessories when docked in a car dock."
