Fiio BTR 5 won't stay connected to the PC

Hello all, I have been having trouble using my fiio BTR 5 as a usb dac. I have the latest drivers for the device but It just won’t stay connected to my pc. It will randomly turn off and won’t turn back on unless I turn it on manually. I have been searching for other people who have had this problem but to no avail. If there is anyone who knows if there is a fix to this problem I would greatly appreciate it!

Check if you’ve set charge while connected to off - If you have, I think it drains the battery while playing and then once it dies, switches off and starts charging itself.
