How to use a music file with a sampling rate > 44.1Khz

Hi,

I’m using Rasplex connected with HDMI to my Marantz amplifier SR7005.
My music library contains 24bits FLAC files sampled 172Khz but when I play them, the amplifier indicates that the sampling rate is 48KHz… Playing directly the file through DLNA on the amplifier says “172KHz”…

Is there a Rasplex setting to set the sampling rate to the original sampling rate of the file?

Thank you very much for your help.

You can try activating passthrough on preferences / system / audio
or mess arround with the output options, you will find that you might have the sampling limited to 48

Thank you.

The passthrough is activated on Rasplex preferences, and the sampling rate is set to be limited to 192 KHz.

My amplifier indicates that the source type is ‘PCM’ / 48 KHz in all configuration of Rasplex.

Any change of the ‘stereo to multi channel’ or others does not change this think. It changes only the number of channels that are used to play the music on the amplifier. The sampling rate is always 48 KHz for all music files (MP3, WMA - lossless or not, M4A - Apple lossless, FLAC 16 or 24)…

Do you have an other idea? Is there any way to have a ‘direct play’ option with music in Rasplex?

Thank you.

I don’t think the Raspberry hardware (more specifically, the HDMI port) supports higher sample rates than 48 kHz.

Ohh

Thank you for the answer.

I’ll check on the net.

looks that itś limited on the kernel side of things

the good thing its that it might be possible to fix if you compile it

OK, but certainly too complex or taking too much time for me…

If anyone had done this, let him know that I’m interested!

Thanks very much for your time.

Try the HifiBerry Digi+ add-on board. It handles very high sampling rates nicely. Google will find it.

Good results with Rasplex and this board.

You would probably need to recompile or get a new kernel if its limited there

the good thing is that its just a value you have to change, the bad thing it´s that you need to know how to cross compile a kernel
