For Poweramp users:
To use V4A with Poweramp properly, you need to follow the steps below.
|Open Poweramp Settings -> Audio -> Advanced Tweaks -> Direct volume control -> Turned off|
Note: To solve Poweramp volume too low after turning off Direct volume control:
Turn on V4A’s PlaybackAGC, set strength to Medium/Extreme, set Max Gain to Infinity, set Max Output to 0db.

For system-provided music players (such as MIUI music player, Apollo etc.):
In these music players, turning on player equalizer will auto disable V4A, turning off will enable V4A.
Third-party players such as TTPOD and Poweramp have no such problems.
