What Dac Chip is This?



So this chip is inside a Plantronics Rig USB sound card dongle, I love the sound and separation it gives when paired with a 660s just my problem is that it doesn’t power my sennheiser all that great too quiet. I’ve tried many dac/amps from topping L50/E50 all the way to Fiio k9 pro and just recently returned a Mojo2. YES that cheap little $25 dongle sounds that good the separation in game are amazing. I’ve been searching far and wide and I can’t figure out who makes these chipset’s. I want to know so I can see what other dacs out there that use this. If anyone recognizes the logo on the chip or any leads I would be greatly appreciated
