Oppo FLAC file playback question.

[SeeMoreDigital]

I have a Oppo 203 and a friend sent me some files in flac 192 khz for rhino quad and my setting is bitstream for hdmi playback on my Oppo and all I get is wierd fluttering sound of the music as if at wrong speed.

This reminds me of some posts on a different forum by people complaining about 'weird issues' when encoding to 2-ch 192/24 ALAC via HDMI to an AVR. I forget how it played out.

If you can... Try re-encoding the 192/24 Flac audio streams to 192/24 lpcm.wav to see if the "weird fluttering sound" is still present...

Hi Peter
I have an Oppo 203 as well. I tried playing a quad file at 192kHz, and was successful. Here are some pics.

Could it be related to the FLAC Level?

The FLAC 'file compression' level can be from 0 to 8. 0 is no compression, 8 is maximum. So 8 would have the most file compression and require the maximum processing to regenerate the 24-bit @192kHz for the channels.

I've a 203 and have had no issues with flacs, most of mine are level 3 to 5 I think.

It is helpful to understand how FLAC works. It has a lossy core predicted stream, and then adds fixup bits to that to get back to lossless. All that selecting higher levels of FLAC compression does is cause the PC to spend more time trying to find a better lossy core predicted stream so that less fixup bits are needed. It doesn't result in a different format FLAC, so it is very unlikely the FLAC compression level is causing this playback issue.

It's also helpful to know which audio encoder was used to generate the flac files along with which version...

I created the flac files from an mkv file and converted to flac with Homer's MMHelper. If that was your question.
