CubiluxUSB C to SPDIF Transmitter, Unidirectional Type C to Optical Audio Output Adapter with 192KHz/24bit DAC for MacBook Pro/Air, Laptop, Computer

Sound is clear and connection is stable. it is compatible with my windows laptop.

I paired this with the EMK 24K Gold-Plated Toslink to Mini Toslink Cable and they work great together to output from my Android phone to the Sound BlasterX G6 external sound card/device.

I have only had it for a few days and will update if issues happen.Sound wasn't coming from my Beam Gen 2 when using this with the optical to HDMI adapter from my Windows PC, a SPDIF output was showing up in outputs but no sound was coming out, even when plugged into a MBP. I assumed the cable was bad and was going to return it.Before doing that I messed around in the Sonos app for a bit, factory resetting the Beam a few times and re-adding it to the system. I even tried downgrading the Beam to S1, which didn't work and errored out. After re-moving, re-adding and going through the "Pair to TV" option in the app it just suddenly started working.So for anyone having issues getting sound to work with Sonos products, it might just be the app and not the adapter.EDIT: So it turns out it's setting the output to "TV" in sources.

As far as the physical product itself it seems good overall but the wire doesn't seem that sturdy so I'm concerned how long it will last. The adapter does output dolby digital but does not work for my intended purpose so I'll be keeping it but more for "just in case" purposes. This is in no fault of the product now that I did more research on surround sound/dolby digital. The rest of this review is not related to the product but might help others with the same situation.TLDR - To get surround sound on PC games you need to connect via HDMI or if using toslink/optical a sound card that has dolby/dts encodingI want to get surround sound on my computer for gaming but most games that have surround sound don't have dolby digital. Most PC games that have surround from my understanding are PCM/LPCM multi channel and then a small selection that have Dolby Atmos or dolby digital. Toslink only supports stereo PCM or dolby digital/DTS. Audio over HDMI does support multi channel PCM/LPCM but I'm using a DP monitor so connecting HDMI would make my PC see 2 monitors which has its problems. For my use case to get surround sound from PC games via toslink/optical would require a sound card that has dolby digital or DTS encoding.

Why did you pick this product vs others?:This is rubbish. Purchased this for my Mac to replace an 2.0 optical convert because I wanted 5.1. Not only did never work in 5.1, no matter what kind of source I was playing, but it sounded TERRIBLE. DO NOT BUY.

This 100% works if you want to send Apple Music native digital hi-res music to your DAC. I’m using an iPhone 15 and have the adapter connected to the optical-in on my Oppo BDP-105. Sound quality is great. If you notice any dropouts just download the file to your playlist instead of just streaming. Attached photos of the hi-res file playing on my phone and the readout from the Oppo on the bit rate. Now if we can only get a search filter for all hi-res lossless albums on Apple Music. Who wants to work on this?

Works perfectly for connecting Mac Mini to a powered sound system. Sound is perfect.

Works great, plug and play. As long as you source is 5.1 it will go through fine. Optical still of use with a laptop to get to a soundbar that didn't have ability to use all of the resolution of my monitor surround sound.
