So you were using this Kanex adapter just fine direct from the Mac Pro and some version of XBMC? And didn't change a thing on the Mac Pro nor plug or unplug anything into the AVR? Didn't upgrade any other software, and no change to OS X?
did you mean to say "it automatically changes back after playing each rip?" If so, what does it change back to, something like 16/44.1 or 48? If so, that's normal, MIDI should only switch to encoded digital out when it needs to, then switch back. What's not right in your setup is you having to manually switch it to encoded digital out just to get passthrough...that should be detected automatically anytime you're trying to pass AC-3 or DTS through to your AVR. And this is with VLC only, right, you didn't have to do this Audio MIDI switching to encoded digital out previously with XBMC did you?
When you have XBMC set up right you never need to go into MIDI, when you choose the DD 5.1 or DTS track in a file it'll switch to encoded digital out automatically behind the scenes. Then switch back to whatever you typically have MIDI set to for music.
OK, so you were on some "older" version of XBMC, do you know which one? Jargon, I know, they all have funny names but also a number and letter usually. And then downloaded and installed the latest version, which is what? This is important because if you read in the Mac XBMC forum there will be lots of threads about x release breaking y, and there's been a lot of them since I think they completely re-wrote the audio engine. That means what works for me in 10.7.5 and 10.1, the version I'm still running because it has been so solid I am loathe to upgrade, may not be working with the same settings
in the newer version you're using.
Do you have a SuperDuper clone, can you boot up off of that to go back in time and test? Can you figure out which versions of XBMC you're trying?
My guess is 1) there's a known bug in whatever version of XBMC you're now using or 2) your answer lies in System Settings > Audio Output settings, between switching things around manually in Audio MIDI and downloading different versions of XBMC and perhaps upgrading something else in the meantime, there's something in the current player settings (XBMC as the player, not Audio MIDI) that is thwarting you. So re-check the audio ones, but it could also be something in the Video > Playback settings, like a sync playback to display setting or adjust refresh rate to match video, because with those turned on you're necessarily involving audio because the video clock is related to audio.
Sorry that's not more specifically helpful...
ADDED: 1PM PST: just opened two mkv BD rips with VLC. It appears Audio Midi is working automatically now. However, XBMC will not open at all.
Hi chefklc. Thanks. I knew you had extensive experience with XBMC (your responses to other posters convinced me to change from Plex to XBMC) and hoped you would help. I understand (now) it's my responsibility to get into XBMC and I'm learning now, but I posted here to hopefully get a quicker solution when I realized my XBMC "knowledge" was minimal.
Rather than specifically answer each of your responses (and possibly introduce more communication errors) maybe it would be more productive for me to be exacting in my situation:
Up to ~15-days ago:
- My late 2009 mini was connected to the Onkyo 805 via the Kanex adapter, and all media was (and still is) stored on my Mac Pro (early 2009): Mac mini->Kanex adapter->HDMI->Onkyo 805, media sourced via wired ethernet from the Mac Pro.
- XBMC (the most current version: I update all my software when updates become available using the Apple Software Update and/or TechTracker) was installed on both computers.
- I ripped BD's and tested the rips on the Mac Pro, but played my mkv rips using the mini (wired ethernet). The current version of XBMC worked (video and audio) on both computers, and I never went into Audio Midi (having read your admonitions against willy-nilly use of the app).
~15 days ago:
- I decided that using two computers to watch movies was excessive and moved the Kanex adapter to the Mac Pro to see if I could eliminate the mini from the mix.
- I just disconnected the adapter from the mini and connected it to the Mac Pro: Mac Pro->Kanex adapter->HDMI->Onkyo 805.
- On the Mac Pro, I double-clicked on a mkv BD rip, XBMC started up, and the movie played perfectly through my Onkyo 805 (outstanding video and DTS 5.1 audio).
- I tested several other mkv BD rips and they all worked perfectly also.
- I then tested DVD Player for some Video TS rips of DVDs. They also worked perfectly.
- I listed the mini for sale.
- I watched another mkv rip a few days later, video and audio played perfectly via XBMC.
A couple days ago:
- I attempted a mkv BD rip viewing. XBMC started up and the video showed up on my TV, no audio on the Onkyo 805.
- Then I did what I said in my original post, attempting to trouble-shoot the problem:
- - 1st thing I noticed was that alert sounds did go to the Onkyo 805 through the Digital Out while XBMC was sending video but no audio.
- - I tried the two audio choices available in the rip in XBMC (DTS 5.1 and mono, I think) and got no sound.
- - I tried a DVD rip using DVD Player and sound went through (Digital Out selected in the Audio System Preference).
- - I attempted several mkv BD rips, still no sound w/XBMC.
- - I then opened a mkv rip with VLC and it played correctly, the audio was DTS 5.1 at the Onkyo 805 (it indicates the audio input).
- - I replayed the same rip using XBMC, no audio.
- - I replayed the same rip w/VLC, and the audio to the Onkyo 805 was stereo, not DTS 5.1! This seemed to occur randomly with several other mkv BD rips via VLC.
- - That's when I checked Audio Midi, and tried encoded digital out (it was not selected automatically apparently) and got DTS 5.1 at the Onkyo 805. This randomness continues.
- - Assuming something corrupted my Mac Pro's copy of XBMC, I removed XBMC, downloaded a new copy, and installed XBMC. Still no audio.
- - I checked XBMC's forums and immediately realized I had not enough savvy to follow the threads: I thought I found exactly what I was looking for but the solution had no relevance to my situation, that I could see.
- - I posted my thread on AVS.
- I made no further physical changes to my HT setup, and still haven't, since I eliminated the mini. And again, the only change made was to disconnect the Kanex adapter from the mini and connect it to the Mac Pro.
- I have Time Machine copies of my Mac Pro dating back to January 15th, 2013.
Thanks again for any ideas.
