zhen^wei, Got myself a Yamaha 7.1 amplifier, and I realized there are BUGs in Eaget M9 HDMI/Optical output.
Problem 1, using Optical
1.0 there's NOT multi PCM output! It only down-stream to 2.CH or RAW.
1.1 if file is encoded to 6-channels AAC, and output set to RAW, no sound come out.
1.2 if file is encoded to 6-channels AAC, and amplifier detect 2 channels.
--notes, forgotten to try AC3 using RAW, coz optical cable already plugged-out.
Problem 2, Using HDMI
2.0 if file is encoded to 6-channels AC3, and output set to RAW, no problem. amplifier detect it's 6-channels.
2.1 if file is encoded to 6-channels AC3, and output set to MULTI PCM CH, amplifier detect only 2-Channels.
2.2 if file is encoded to 6-channels AAC, and output set to RAW, no-sound come out from amplifier.
2.2 if file is encoded to 6-channels AAC, and output set to MULTI PCM CH, no-problem. amplifier detect it's 6-channels.
hope you forward the problems to Eaget developer. hope they can enhance the Optical output, and solve the HDMI Multi PCM CH on 6-channels AC3 problems which outcome only 2-channels. Thanks.
few corrections, <sorry for the previous post>Problem 1, using Optical

<since it only support PCM 2CH in setup>.--notes, forgotten to try AC3 using RAW, coz optical cable already plugged-out.

this time i'm sure, no further correction, please forward to developer. maybe they should do this, if it's NOT AC3/DTS/TrueHD/DoblyHD or anything that which is standard sound stream to amplifier during HDMI sound set to RAW, do the conversion, otherwise just by-pass. <should be very easy to fix the bug>Thank you.
