Fiio X5 (1st gen) USB DAC feature not working

I’ve been trying out an old Fiio X5 that I found for cheap and the USB DAC feature isn’t working. Is there any way to fix this? Thanks in advance for the advice! (Current FW: 2.7)

not working for your phone or pc?

not working on the pc =(
currently using a lenovo ideapad slim 3

did you install the fiio app for pc?

yup, it doesnt want to connect

I have an X5 and I would tell you to change the cable. I don’t know why but some USB cables will just not work. I tested a few cables on another device and they were all ok but only one would connect with the X5…
