Answer
MCP61M-M3 V7.1 came with VIA VT1705 6-channel HD audio chipset. The header supports HD audio by default, if connect an AC’97 front panel audio, may occur either front or back audio is working only, please don’t tick off "Using Front Jack Detect” to let both of front and back audio are working. If connect HD Audio Front Panel, please tick off “Using Front Jack Detect”.
