Hi All
Is there a fix for playing 4.0 multi-channel FLAC files over HDMI, in OE v3.2.3/Frodo 12.2 ? I have a large number of quadraphonic discs I wish to transcode to MCH-FLAC, and initial tests are disappointing.
I have searched for similar reports (ie: 4.0 FLAC downmixed to 2.0), but find nobody raising this issue. xbmc is recognizing the number of input channels as 4 (indicated by hitting "O" key during playback), but refuses to send anything but Stereo PCM over HDMI.
Curiously. odd-numbered MCH-FLACs play "correctly"... both 3.0 and 5.0 files are formatted as 5.1 PCM > HDMI, and map to the correct locations. My processor identifies the input stream as 5.1 PCM (L/ C/ R/ LFE/ LS/ RS). Six channel files behave as expected.
Audio output in xbmc is configured for HDMI/ 5.1 channels/ AC3/ dts/ AAC/ Multichannel LPCM calable. While the processor is only HDMI v1.1 compliant (a 2005-vintage Anthem D2), it accepts up to six channels of 24bit/96KHz PCM - sufficient to the task, if only xbmc would format the appropriate number of PCM channels.
Can anyone say how to pass 4 LPCM channels over HDMI - unmolested by downmixing to stereo ?
Thanks in advance for advice and pointers.
