Hi,

I am using a Mac Mini late 2012 with a Native Instruments Audio 6 sound card. The Mac speaker configuration (Audio Midi Setup) is set to play stereo on this device on channel 5 and 6 of the sound card. While all applications I tested (VLC, Chome Browser, Spotify, iTunes etc.) do use these channels XBMC uses 1 and 2 only. I tried changing XBMC audio settings but nothing helps

I have also created an aggregated device in the Audio Midi Setup that only uses channel 5 and 6 of the soundcard, still XBMC finds its way around that to channel 1 and 2.

Versions of XBMC tested: 12.3 32bit 12.3 64bit, 13.0

Thanks,
Robert

Can you test this version please and report back?

Thanks for the quick reply. This version is not able to produce any sound through the Traktor Audio 6 at all. Only when I set XBMC to use Mac's built in device I get audio

Can you test this version please?

Done, this one uses channel 1 and 2 only as described in the original post.

Thanks!

Can you post a debug log (wiki) with this test version?

have you set xbmc to speaker config 2.0? And also disabled LPCM (which is a setting in frodo only though). You can go back to frodo - the testbuild i provided you is not for your issue (i missinterpreted your report).

DJRM · 2014-05-13, 11:22

With the versions I tested before the initial post, I tried 2.0, 2.1, 5.1. Please note that the sound card has 6 channels out.

With the later versions you sent me, I tested 2.0 only (I think).

I will try the Frodo the disabled LPCM this evening. Which Frodo should I be using, 32bit or 64 bit?

**Memphiz** · 2014-05-13, 14:01

doesn't matter

DJRM · 2014-05-14, 07:07

To disable LPCM I have to select Audio Output HDMI, while the output is not. I can however select the Traktor Audio 6 as audio device.
When I select analog, it is automatically disabled.

But this all does not help, all audio goes to channel 1 and 2.

http://mirrors.xbmc.org/test-builds/osx/...x86_64.dmg <- this might respect the right channel map ...

Also if this build doesn't work (and if it works too) - please try this afterwards in any case:

This one should really fix it...

Cpuroast · 2014-05-15, 04:59

Would this fix also apply to the issue when playing back 5.1 LPCM over HDMI for non AC3/DTS formats such as 5.1 FLAC or 5.1 AAC where passthrough is not an option?
