I'm having this really strange issue where when i play a video file that has multi channel audio such as AC3 it seems to crash the system audio. By crash i mean before i play the file i have perfect audio, in appletv frontrow, in xbmc for all the menu sounds etc; but after i play the file then press stop (as sound doesn't work), i loose ALL sound, eg no menu clicks in xbmc, no menu clicks in appletv frontrow, nothing at all. The only solution is to reboot the machine. Everything i have to watch is recorded in HD so

I'm not sure what started this (have been running this setup for years), i say that because i was tinkering with new versions then i went away for work and now i can't recall exactly when the problem started.

I'm currently running Dharma Beta 4, i have a Crystal HD with the latest driver (27oct2010) which i download using the launcher add-in link, I output via hdmi to my TV (no 5.1 decoder, just the tv - its in the bedroom).

I've tried every combination of Analogue/HDMI with Default/Built In Line Out and nothing seems to make a difference. I haven't checked the options in system>audio for multi-channel capable receivers although in desperation i tried that once also and it didn't help (as expected).

Following is the log for an mkv file with ac3 audio

I noticed in the log the following lines which caught my attention:
09:25:35 T:51919872 M: 11472896 NOTICE: Opening audio stream: 1 source: 256

First i say the 'won't transcode', but then it says it finds 0 channels?

This file, along with the other dozen i've tried from various sources, is working perfectly on my mac, windows pc, linux etc. XBMC/quicktime/vlc/whatever. Definately not a file problem.

I've been tinkering with HD, xbmc, crystalhd, dts amps etc for years and i gotta say this one has me beat. Does anyone have any ideas on what to check?

Thanks in advance!

I sure am struggling with this. In desperation I reset the appletv to factory defaults and setup again from scratch using latest everything. No joy, same problem. Please help?

this quirk has been covered already and is a know issue. search and ye shall find.

Not sure of this is related,

Using latest firmware atv + Dharma RC1 HDMI connected straight to TV. I have HDMI set as audio under systems. Using a AC3 5.1 file, I get really high pitched noise instead of audio. This is what happens when I start the movie, issue seems to be related to:

19:34:36 T:54480896 M: 4866048 ERROR: CCoreAudioDevice::SetMixingSupport: Unable to set MixingSupport to 'Off'. Error = 0x65706f6e (nope)

Interesting enough on the mac using the same Dharma version, the same file plays fine. so it seems like a setup issue, please help.

===stoped movie===

I came across another earlier thread about this (missed it somehow... Fail). I think my issue was fixed by going into the appletv settings (as in the actual Apple TV settings, not xbmc at all), and disabiling the DTS setting.

Do u remember where you found that setting? I can only find Dolby digital?
