Hi!
I just got my chromebox today (i3 model), and I've successfully installed Ubuntu in a dual boot mode. I got a Pioneer VSX-923 AV receiver, that supports most audio formats. My problem is that I cant get system audio working (GUI sounds etc)! The audio is not working in Chrome OS either. I've chosen my receiver in the audio settings in Kodi (HDA Intel, PIO VSX-923 on HDMI #0), and since I've enabled pass through audio, All movies and TV-shows (even those who only have a 2.0 sound track) got audio, but no system audio. If I change the resolution to something else that 1080p, I also get the system audio back, but now the resolution doesn't fit my TV. I also have issues with the well known black screen, when I reboot or change the source on my AV Receiver.
If I go to the audio settings and use the Output configuration "Fixed", My AV receiver is showing PCM on the display (and 5.1 ch, since that's my setup) and now I also got System audio! The problem is that If I'm watching a DTS-HD movie, it still says PCM on the display.

Will there be a patch that fixes these AVR related issues?

If your receiver reports PCM 5.1 then you aren't getting passthrough. It sounds like your audio is being decoded on the Chromebox. This shouldn't be happening with a VSX-923. Possibly an Ubuntu thing and not a Kodi issue.

I only get PCM if I choose "fixed output configuration" If I choose "Best match" or "Optimized", I don't get any audio at all. Since I get a black screen every time I do some changes on the AVR, it seems like this is the EDID problem.
