STM32L476 - Elimination of ST Link part

Hello, I'm using STM32L476 Discovery board. Using the ST Link (5v), Live Hearing, Record and play back functions are working. But, I'm trying to eliminate the St-Link part from the board, for this purpose i tried giving 3.3v directly to the jumper JP6. In this case, Live hearing is working but record and playback function not working. So i would like to know whether it is because of power consumption, Clock cycle or any other reasons. Also can this issue be resolved by directly supplying 5V to the jumper with 3.3V Voltage regulator? Any kind of suggestion would be appreciated.
