Currently, I'm trying to use the Linux built-in USB audio gadget kernel module. If it works, the audio system could be used as an external USB audio device on several operating systems as well. If anybody has experience with this subject, I appreciate your support:)

That sounds really interesting as I'm also using BBB for some audio array processing projects. Was there any progress on that side of things ?

I've already compiled Linux with USB audio gadget support. When I load the kernel module "g_audio", I'll get an additional sound device on the BeagleBone and on the host PC as well. But if I play some files from the host PC, there's no sound coming out of the audio system. My question is, how do I connect the audio codec driver with the USB audio gadget driver to route audio from the host PC directly to the audio codec. Any support would be great!
