Hello. May I join in. I have similar problem with DeskFx Audio Effects. Switched on power. Selected my device. It kept showing Waiting for streaming. I was lost figuring out how to connect it to YouTube music. Other apps would automatically display the current audio channels. Tried to uninstall but it remained installed. Hopefully I might get solution from tech savvy guys out there. I'm somehow relieved knowing I am not the only one with this issue. Thank you for sharing.
