It’s known that the speaker audio in skylanders trap team doesn’t work in the game, as when the speaker is supposed to play audio, the portal doesn’t light up the hole for the trap items. It is mentioned in the comparability list, but I believe the cause for this problem not mentioned is with the drivers. I remember hearing in the discord that cemu has sub-par usb driver support, and the portal has to be installed as a usb input device. I know that the process is easier with dolphin emu, where they apparently have got the portal speaker to work, by using a different driver to interface with the game. It makes using the portal tricky due to having to change the driver for each emulator every time, but I also believe the driver support is why the speaker can’t play. Hopefully development on the usb drivers may help any other usb devices in some way, too.
I don't remember for sure anymore but I believe the issue was due to Windows HID API not exposing the second usb device which is used for sound playback. The libusb PR likely will fix this.
