Topping D50 III optical input bug with 44.1kHz files

[unpluggged]

Khadas TB.

How the TVs were connected? I mean, the KTB has no optical input...

Coaxial of course,SPDIF doesn't care.

You do tend to get different jitter profiles with them.

..and a little noise too.

Posting an update as I seem to have possibly solved this issue by trying my other Chromecast Audio (I have two) with the D50 III. So far no drop outs with 44.1 kHz music. So it seems to be a problem with my original Chromecast Audio, but only with this DAC. Very strange that it's only with 44.1kHz music though.

Strange! Perhaps it's a poorly performing clock that's too marginal at 44kHz for the DAC to reliably extract a good clock feed.

I'm gonna bet it has a crystal at a multiple of 48kHz, and is trying to derive the 44.1 imperfectly from that. Whereas all the other most used sample rates (48, 96 etc can be derived perfectly.

88.2 kHz was fine, though

Probably rules that theory out then.

OK at multiplying, poor at dividing? Sounds like a school report
