Skylanders Trap Team Portal Speaker Stutter

[KaoKraft]

Current Behavior

All audio coming from the portal speaker sounds incredibly distorted and choppy.

Expected Behavior

I expected it to sound like this, clear intelligible sound out of the speaker. (Forgive the low quality example)

Skylanders.Trap.Team.Chompy.mage.s.Chompy.power.mp4

Steps to Reproduce

I started a new game, skipped the cutscenes and placed down my skylander. Then once I loaded in, I put the trap into the portal, which triggered the villain summoning screen, and started the poor audio quality. My portal drivers are the default ones, just plugged into my pc via a usb 3.0 hub.

It helps to know your CPU/Mainboard too, there are some usb audio issues quite specific to the ryzen platform.

Good to know, I am in fact on Ryzen.
Specifically Ryzen 9 5900x, along with an rog B550-A board

You will need USBview or the Device list of HWInfo, but can you discern if the hub is connected to a CPU ports or the chipset ports

In HWInfo, Chipset Ports are those attached beneath the B550
CPU Ports are attached Beneath the CPU PCIE GPP Bridge

I am away from my pc for a couple days, but I’ll make sure to check on that once I have access to it again. Thank you for the responses

I heard from someone in the skylanders reverse engineering discord that it was because cemu uses a inferior USB driver from libusbK, which is the driver dolphin uses with portals for skylanders
when I asked in the discord if it was planned to add support for it, someone confirmed that it was planned, so I guess the problem might be solved when that happens

I think this issue explained the same problem (or similar) : #902

[slice-the-idiot]

so with libusb support now avaliable for only linux

can we get it on windows aswell?
please?

Hi, I've done a bit of digging and it seems that the issue revolves around the windows version sending only the first 32 bytes of the music data - here are logs captured in wireshark for the sound that plays when placing a trapped Chompy Mage.
The first 32 bytes are always identical, however the data send by Cemu on Mac contains additional 32 bytes in each packet (64 total).

chompymagewindowsdata.txt

Also worth noting is the research by Marijn Kneppers - where he remarks that data should be indeed send in 64 byte packets.

I'm hoping that someone more knowledgeable will carry the torch. If I could assist further please lmk!
