‘Slow’ playback of 192/24 flac

[Phorize]

Hello. I have a chord qutest with a Cambridge audio np30 acting a a transport. They are connected by coax, rca out/ bnc in. I have bought 3 192/24 albums. Over Dlna (Debian server/cat 6) they play back very slowly, as a 45 record on 33 rpm might. There is also some distortion.

The same files playback properly over dlna to vlc on my iPhone.

Any thoughts about what is causing this phenomenon and how to respond? I am contemplating buying an Allo Digione anyway as np30 is deprecated and running a very out of date software stack.

If there is another way to connect the two units try it.

From the page on your Cambridge, it only does 96 khz. It would be odd, but maybe it is playing 192 as 96 khz? That would be 50% normal speed.

You could downsample them to 96 khz, and see if they play normally which I'd expect they would.

Thanks. I try with a toslink cable.

Thanks. It would be odd as I’m assuming that the output of the np30 bypasses the internal dac(which does indeed only handle up to 96/24) and passes the stream directly to the rca or optical output and in to the external dac. You might be right though. It might be a queue for me to finally upgrade my transport but I’ll see if I can figure out what is happening out of interest.

Well under digital outputs on that page I linked earlier is this:

DIGITAL OUTPUTS
S/PDIF Co-axial and TOSLink Optical 16-24 Bits, 22.05-96kHz

Now digital out does bypass the internal DAC, but it still must have the chips to support higher sample rates even for digital out, and apparently it stops at 96 khz.

Thank you-well spotted. I’m slightly embarrassed that I didn’t RTFM properly before posting. If I’d done that on the openbsd mailing list I might not have survived

Looks like I’ll be ordering a Digione today!

I don't think we'll dock any points from you here.
