ROM question topic

Hello, from what I've gathered 4.4.3 and 4.4.4 ROM's seem to have no audio during BT calls via a BT headset. My m4 is rooted, running TWRP and bootloader unlocked via HTC Dev, so I can't go back to a Stock ROM. What options do I have for something that HAS working Bluetooth Audio? I've heard I would need a 4.4.2 ROM, but all I've found are stock 4.4.2 ROM's, or am I missing something?

Thanks in adv.
