There are indeed ways of achieving AoIP input in Linux, but I won't lie, they're all a massive pain in the arse, and (as a linuxy person) I can testify significantly less reliable than just running DVS or Livewire on Windows Server.
Either you go hard mode, and use ffmpeg/gstreamer to intercept the AES67 RTP packets in pcm_s16le format from a multicast (which is doable with Dante in AES67 mode, but really difficult to configure).
Or, you can use the merging audio alsa driver, https://www.merging.com/products/alsa_r ... s67_driver
. This... works.... not reliably, but it does do the job if you're a sysadmin whizz and know how to tune a computer for RT to an inch of it's life. This has the advantage of an ALSA device being much easier to work with than interfacing directly with AES67, but the disadvantage of being completely opaque, and there's no real way of fixing if if, like mine you get audio glitches after a few hours.
Sorry, no easy option, and no option as reliable as a dedicated well-setup Windows box tbh. But I'm happy to help if you have any specific questions!
