If that’s the case, use coax cable. I found on mine using coax even cheap one work. I’m not sure why schiit is finicky on optical and not on coax. Try that out and let us know. I have 2 dacs from them regular modi and multibits. To my ear, multibit really has strong bass and mid where users calling them meat on the bone. My favorite and most transparent and balanced to my ear was smsl do200 mikii. I have pro connected to smsl via optical then from smsl to amp via xlr. Polk legend known to be power hungry for having 4 ohms and low sensitivity. I have them being fed on 450 watt mono block. Sound with wiim RC bring music artist to life. Let us know!
So bizarre…I just ran into the same problem today. I originally used a 3 foot Monoprice optical cable, the higher end one with large silver connectors and silver sheath. Worked fine at 192 with the Schiit Modi 3. I didn’t like the look or length, so I ordered a 1 foot Blue Jeans optical cable. Much nicer on the end table. Worked fine at set up and a couple weeks. Then today I go to listen and no sound. I reseated the cable. Rebooted and nothing. Went into Wiim settings and changed to 96. Tested fine. Just noise at 192.
Have you tried the optical cable that is included with your WiiM device, these fully support 24-bit 192 kHz.
I have not just because my other two cables support 192. I reported this to Blue Jeans and they did respond asking about cable condition. We shall see if they anything. I will test the supplied cable tomorrow
