Hi
I have been trying for some time to stream music tracks in excess of 60 minutes without success. The manufacturer of my renderer (Chord) can't replicate the problem and MC plays these tracks on my PC without a problem. I am streaming over Powerline Ethernet at 96/24 WAV (no other settings play all files consistently).
I thought this was just long albums with a single track in excess of 60 minutes but just tried playing an album where first track is 65 minutes and second track is 10 minutes and MC/Gizmo just skips to the latter.
Any suggestions?
Keith

File format?
Perhaps you are converting and running into the 2 gig wave file conversion limit?

Thanks Bob this looks like the problem but what is the solution?
By setting the sample rate to 'same as source' rather than 96k then for a 60+ minutes track the file size obviously reduces and the track plays.
My only problem is that 24/96k files (with short tracks) then return a 'File Format Error' on the renderer.
These are all Flac files (standard and hires) on MC.

Try streaming PCM instead. L16 should work and possibly L24 if you are lucky.

I am streaming L24 PCM but it comes up as a WAV file on my Control Point. The only MC options I can see are L16/24 with/without header.

Try "without header" ...

[keithsonic]

I get a 'File Format Error' with both L16 and L24 without header. This is playing a standard 16/44 AIFF file.

The L16 format 16/44 is REQUIRED to be supported by all devices conforming to the DLNA spec.

I have finally twigged why my Hires files won't play with L16 or L24 'no header'. The files I tried to play are ISO rips converted to Flac in MC - when I look at the sample rate these are encoded at 352.8 khz which, obviously, my renderer won't play as straight LCPM. When I transcode everything to 96/24 then I have no problems (except inability to play long files due to WAV limit). I am not sure why I end up with such a high sample rate as this is not selectable and I can't see any way to convert files to a lower sample rate.

bob, I won't mention "SinkProtocolInfo" -- oops I just did it

Well isn't it nice that LPCM is the ONE format that will work that way?

I assume your sample rate is high because it maintained the original sample rate from the iso. You should be able to change that during conversion to FLAC using the DSP.

If you select L16 as the output format for DLNA and choose a specific sample rate it should be fine as well.
I think we are going to change the DLNA "same as source" conversion to max out at 192k and 176k.
