How are you attempting this? Doesn't the Switch just have HDMI out and a lineout?
USB. The newest update (4.0.0) silently added support for USB audio output with wireless headsets using a receiver. I was hopeful that USB audio devices were also supported. That's not the case. I'm going to look into purchasing an HDMI switcher with Toslink and coax out to see if that works.
Try a powered usb hub in between. Might not be enough power.
HDMI de-embedders and Schiit DACs do not mesh well. I posted about my attempt to use one with my Oppo here: http://www.superbestaudiofriends.org/index.php?threads/sacd-players.1267/#post-40046. If you do get it to work, please let me know brand/model.
I get audio from my WiiU into my Yggdrasil by HDMI --> TV --> HDMI ARC --> Oppo --> S/PDIF out --> Yggdrasil. Not ideal, but it works.
I had success using the Fulla 2 directly with the Switch. The Yggdrasil did not work. I've also had success using a HDMI audio extractor with optical out into the Yggdrasil with a PSTV. I would assume that this would work with the Switch as well, but I haven't tested it.
The brand was SGRICE, but it isn't available anymore on Amazon.
The equipment should be delivered Saturday. I will let you know if it works. Thank you all for the advice and information.
Using an Xbox one as a splitter works.
Success! Using the Kanexpro box, that Zonto mentioned in the thread he posted, with coax 100% works with the Nintendo Switch. This is the device https://www.amazon.com/gp/product/B009KAU0WO/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
Crazy. I have no idea why it would work from the Switch, but not from my Oppo into Yggdrasil. I tried all outputs and settings on box and player too.
That's unfortunate. I wish I could help but I have zero experience with the Oppo and you have probably tried everything already. Using it with the Switch isn't perfect though, it seems every now and then there will be a quiet but still audible pop or click in either the left or right channel. Not annoying enough to ruin the whole experience but it's still there.
