Multichannel flac plays fine here - that sounds like a setup issue with your audio.

ive just stuck the gigabit card in, seems to be an instant improvement. When copying files to my XBMC from the NAS box over using WinSCP, it still seems pretty slow. Strangely copying files from my other PC to XBMC is fine now :S but anyway sorry to get off track, i know this isnt a general support thread! Either way it seems blu rays are streaming properly now, or at least fast enough to be useable with the new card.

With regards to multichannel flac, it just freezes, the play timer comes up but its sits at 0:00 and when press stop it just locks up XBMC. Are there any particular settings I need to set?

Thanks for your help

The most relevent would be:
- must be HDMI or analog for multichannel flac unless you are trancoding to AC3 - optical cannot pass multichannel LPCM
- receiver supports multichannel LPCM
- speaker config > 2.0

From log it looks like ALSA rejecting it - check your ALSA config.

Seems to be the nightmare of Linux audio - sorry, I'm a Windows programmer so I can't help you, but I sure wish someone would write a guide for you guys. Setting up ALSA seems to be the biggest single issue ppl have with XBMC Linux.

I tried the sample file and it plays okay here - some glitches in the file encoding itself, visible in VLC too, but otherwise watchable. Turns out I did have a mono file here too, and it plays fine. I confirmed that AE is correctly upmixing the mono to stereo correctly.

I had a look thru your previous log, where you played an Abbott & Costello flick - one thing I noted was it was upconverting or transcoding to AC3. As a test, can you disable "Receiver supports AC3" in the Audio Output settings of XBMC and try again? Just want to see if that trancoding to AC3 is an issue.

Gave that a shot and it fixed the issue....

Not trying to bug you, just wanted to see if you had a chance to look at this. Thanks!

Hey everbody,

I'm currently strugling to get my media center up and running. Today I installed the AE version by accident to solve a problem with MPEG1 playback. Everything worked fine including audio (either via HDMI or via analog out).

However I want the system to put audio on both outputs so I built myself a nice little .asoundrc. It works wonderful: 5.1 on analog output to an old surround system and 2.0 on HDMI to a stereo TV.
However I could not find the custom output option any more (I am sure it was there before replacing the ubuntu version with the git version). And, as you stated in this thread a couple of times, it is gone.
Whatever, I thought, just replace it in the config file:

Code:
<audiooutput>
        <ac3passthrough>false</ac3passthrough>
        <audiodevice>ALSA:beide</audiodevice>
        <channellayout>8</channellayout>
        <dontnormalizelevels>true</dontnormalizelevels>
        <dtshdpassthrough>false</dtshdpassthrough>
        <dtspassthrough>false</dtspassthrough>
        <guisoundmode>1</guisoundmode>
        <mode>0</mode>
        <multichannellpcm>false</multichannellpcm>
        <passthroughaac>false</passthroughaac>
        <passthroughdevice>ALSA:beide</passthroughdevice>
        <stereoupmix>false</stereoupmix>
        <truehdpassthrough>false</truehdpassthrough>
    </audiooutput>

The "beide" device is the one which outputs to both devices.
Unfortunately xbmc ignores this setting and chooses to use hw:CARD=Intel,DEV=0 instead (which is the surround system).

The log for that specific part is:
Code:

Dear developers: I need that functionality!

Please please please ... enable us to use stuff that already works. Its really wonderful, that you are doing easier to set up possibilities and the whole settings in AE work just like a charm. Really really great work, to be honest! However the mutliple output thing is not yet done (you state it as a thing to come). So please dont take that funktionality away from us Confused

My suggestion for this problem to stay newby friendly:
You might add all predefined interfaces in .asoundrc or asound.conf to the configuration menu. Like this new users do not get confused by a huge load of possible (partly not working) settings and experienced users still have access to all features provided before.

However, if you can spot a possibility how to use my settings now (or if I just made a dumb configuration mistake) please share your knowledge with me Nod

EDIT: The interesting thing is that the lines in the log above also appear when xbmc is started the first time with "normal" audiooutput chosen in the menu: "ALSA:hw:CARD=Intel,DEV=0". After having a look in the code, adding some debug outputs and recompiling it seems that the sinkName in SoftAE is always empty when xbmc starts. Thus the check at xbmc/cores/AudioEngine/Engines/SoftAE/SoftAE.cpp:277 always fails at startup. I did not get the big picture - so this might be a legit behaviour. However it seems a bit strange to me, since the message sounds like "There is a configuration error".

Patience - this is rather obscure (transcoding mono to AC3) - I have made a note on the to-do list.

I've had similar issues from time to time (I think I have that same Dire Straits SACD rip, unless you ripped it yourself). It's usually solved by closing XBMC, letting it stay closed for a couple of seconds then restarting it. Sometimes playing some other format that you know works (like MP3), then playing a FLAC file makes the audio work. Lately though I haven't had any of these issues (I recompile quite often).

This really isn't the place to ask that. If you read the news page you'll see that AE will be included in the next stable release (ETA unknown I suppose). After that it's completely up to the Linux Mint maintainers to provide a package for it. Have a look at the wiki or the forum (I think there's a sticky for it) if you want to learn how to compile XBMC yourself. It really isn't very complicated at all.

Added the bug ticket + patch http://trac.xbmc.org/ticket/13075

Not sure if ALSA can handle this stuff always but for now better than no sound at all.

This is the same issue I am having. To work around it I compiled with PulseAudio enabled. I like your fix better since I hate PulseAudio.

Still having a weird issue with my hdmi not being detected. I know my ELD data is invalid but XBMC is logging a different error:

@drivesoslow - yes, that pull request is aimed at some of the issues you're having. I expect it to be merged before June 10th. It's just waiting for review and the thumbs-up.
