One feature I think would be fantastic is to better support bluetooth devices such as car radios which already have an amplifier and equalizer. When paired with a bluetooth device which has a built-in amp, it would be great for Poweramp to output a flat non-preamped signal over bluetooth. This way, amp volume, bass boost and various equalizer settings can be controlled only by the external device. However, when not paired to a bluetooth device which has it's own amp and equalizer, the Poweramp equalizer and volume controls would be used. As always, when wired ear buds/headphones are used, Poweramp controls everything. If this is already an existing feature, my apologies but I've not been able to figure out how to do this. If anyone already know how to do this, please point me in the right direction.
