24 Bit / 192 kHz SPDIF optical output issue.

[JazzBohemian]

Hello, I have purchased a Wiim Pro Plus and despite trying it on two devices that support 24 Bit / 192 kHz via the optical output, I am unable to get a 24 bit / 192 kHz output. I can only get output up to 96 kHz. When I play the 24 Bit / 192 kHz output test demo from the Wiim Pro Plus settings, I hear distorted sounds. I have tried with two different DACs and two different optical cables, but the issue persists. I read on a forum that the issue could be resolved by using a Coax output, but I don't have a Coax cable to try this. Also, if we cannot get a 192 kHz output from the optical output, why is this option available in the settings? I am awaiting your assistance. Thank you.

I got my Wiim Pro this week and 192/24 via optical only worked with the supplied cable, with a supposedly higher quality cable there was no playback at all when playing a 192 track via Tidal. Are there any characteristics of optical cables that indicate whether or not 192 will work? My Wiim Pro is connected to a Chord Qutest.

What is the length of the cable?

Does it work with lower bitrate?

Note that the WiiM cable is of high quality regarding transmission. Just don't look as fancy as others.

It's a 50cm Oehlbach Opto Star and it works perfectly except when 192 is played - it's by no means an expensive cable but seemed of good quality so I was a bit surprised

Probably just a low quality cable that looks nice?

Yea I guess, anyway it works well with the supplied cable so I'll just go with this one

Ok ignore my previous posts, I just tried the Oehlbach again out of curiosity, and now it also plays 192 - no idea why, the connectors were locked as firmly before as they are now, but now it just works good news I guess

Tight bends in optical cables can affect the stability of higher frequencies, but as it's only 50cm I doubt that was the issue.

Maybe there was some dirt on the connectors? That can reduce the light and cause high frequencies to fail.
