USB sound card and PCIe expansion board cannot be used at the same time
I can't use USB-Audio-A-For-PI5 because USB Error 71.pi 5 not connect usb audio .OS Bookworm.
I used the following methods to initially solve the problem, but they both cannot be used at the same time 1.take out PCle M.2 board 2.take out fan connector 3.power on 4.after boot and can use USB sound card.Connect fan connector reboot raspberry board again.Now want to use PCle m.2 in the same time.but can not use the same time
