Review: Good Solution for PC Gamers - Atmos and DTS:X Support from GPU HDMI - I purchased this product to connect my NVidia GPU (HDMI) to my gaming monitor and Atmos soundbar. This is an updated review. I had purchased this product and was originally dissatisfied with it and returned it. I am a PC gamers that was attempting to connect my NVidia HDMI port to my soundbar eARC port and my gaming monitor. My two concerns in my initial review was that BK-929 appeared to be locked to 120Hz even though I was on a 1440p display with much higher refresh rate. Adding custom resolution via NVCP did not work. Additionally, the BK-929 was using the EDID information from my monitor instead of my Atmos soundbar. This meant that the BK-929 telling Windows 11 I only had two channel stereo and no other sound formats were available. This was/is a common problem I found with units from other manufactures I tested. For years companies that created all these affordable "audio extractors" would only support users with televisions which accurately report audio formats. However, PC users were left out as nearly all gaming monitors don't have ARC/eARC. Orei actually read my review and reached out to me after I had returned the product and offered to help me find a solution with a firmware fix. The unit they sent out had an updated firmware that unlocked the 120Hz restriction and was able to support ~220Hz which more than adequate for gaming; however, it didn't fix the issue with unit only using EDID from monitor and not soundbar. I communicated with Orei support and they sent me an adjusted firmware that finally unlocked Dolby Atmos and DTS:X through Windows 11. Orei seems like a company that actually cares and are proud of their products. I'm excited that a solution for PC gamers wanting to use use their GPU's that already have the audio capability for Atmos and other formats finally have a product that will work with eARC connections to audio systems without needing a $400 adapter or an AV system with HDMI 2.1 passthrough. This is important as many of the smaller soundbars that are appropriate for a computer desk typically only come with eARC port and not HDMI input (ie: Beam G2/SB400). I'm unsure if the firmware fix was specifically made for me, or if it will fix the issue for everyone. However, if you're planning on using this device to connect your PC GPU to an eARC port on your sound device do know that Orei support is aware and has a solution for PC gamers.
Review: Initialization problems - I am using the BK-929U with a Xumo Stream box, Samsung Smart TV, and Sonos Arc Ultra. The device will only initialize properly about 50% of the time, and must have it's power cycled after all other devices are powered on. This is quite inconvenient. but once initialized correctly, it will operate reliably for the TV viewing session. I installed a remote controlled power outlet so that I may cycle power on the device from my smart phone.

### ⭐⭐⭐⭐ Good product, can be improved
*by A***V on August 28, 2026*

Pros: - Works out-of-box with NVIDIA GPU and eARC-only Sony soundbar. No connectivity issues, no tweaking required. - Supports Dolby Atmos / DTS:X over HDMI - much better sound quality than optical connectivity I used previously. Cons: - Expensive - Uses proprietary power brick instead of USB power
