[Sonic Defender]

Thanks for looking and hopefully helping. I have Android 7 on my LG G6, waiting for 8, and I have turned on developer options. I have seen somewhere, that for Bluetooth anyway you can tell Android to use 44.1 rather than the default internal 48kHz. The problem is I can't seem to find where to do this (assuming it is even possible). Any help would be appreciated. I typically use Onkyo HF Player, an unlocked version of the app. Thanks in advance.
