Review: Took a minute - I bought this alongside the LG S90QY sound bar. Even though I had everything plugged in correctly, the WOWCAST kept blinking white. Also, my TV (also an LG) wasn't finding my sound bar as an HDMI ARC device. As a bluetooth device, the TV found the soundbar with no issues. I kept checking the cables, double checking (and even doubting myself) that I plugged this into the correct HDMI port (I did). Even though I downloaded the LG app, and it let me update the firmware on the sound bar, I wasn't getting anywhere. So, I finally just unplugged the power from everything, and then plugged it all back in. All better! Works like a charm now. Best audio I've ever heard? Probably not. Best for the money (bought it on 40% off sale) and considering it actually works, certainly. I had a Bose sound bar prior to this one, and despite everything I ever tried, including contacting Bose and LG it never worked through HDMI-ARC. And that was with a direct cable connection!! I'll never buy another Bose product again, for that reason specifically.
Review: Small but mighty - So here’s the story, I have an Apple TV connected to a Hue synch box that’s connected to the sound bar to finally connected to the TV. This setup has been a nightmare to say the least. Screen would black out, I would lose audio, or delayed response time. The LG wowcast has solved all these problems! I am now enjoying my Hue lights effects and Dolby Atmos sound with maximum compatibility and ease of use. Cables to the TV are not completely eliminated as I do have to connect 1 HDMI cable from the Hue Synch box to the TV so (Apple-Hue-Tv). But that’s not a problem for me at all. Highly recommend this device, cheap, invisible and effortless to use.

## Questions & Answers

**Q: There' a delay between picture and sound when using wowcast. There's no issue when connected by cable. How can i fix this? Sq90y bar.**
A: Mine stopped working after a couple months, with I had a better answer for you

**Q: Can anyone explains if it worth the money? Over hdmi cable or Bluetooth connection?**
A: It’s worth the money, l had wired system and now no wires to the sound bar, woofer and rear speakers.

**Q: IF I use the sound bar in bluetooth mode does the wow make any difference**
A: The LG WOWCAST WTP3 connects to the USB and HDMI ports on a TV so it can transmit audio wirelessly to a compatible LG Soundbar. It transmits Lossless Multi-channel Audio (Up to 12 ch of Uncompressed Sound).Bluetooth can only transmit audio in mono (single channel) or stereo (2 channels). Bluetooth does not support 2.1 channels of audio or any surround sound formats. Bluetooth can’t provide the bandwidth to support more than the left and right channels of audio...^Ivan

**Q: My e arc hdmi isnt on the back its on the side hdmi slots. Will this work?**
A: The LG WOWCAST WTP3 requires a USB and HDMI eARC connection to any LG TV (TV must have an HDMI eARC port) but it is only compatible with select LG Soundbars. Compatible LG Soundbar Models: S95QR S90QY S80QY S75QR 2021 Models SP11RA SP9YA SP8YA SPD75A 2020 Models SN11RG SN10YG SN9YG SN8YG SNC75. You need to connect the LG WOWCAST to your TV via a USB cable for the power supply. You can also connect to an electrical outlet for a stable power supply. It should be installed on the rear panel of your TV, and it comes with double-sided foam tape that you can use to attach it to the rear panel of your TV. HDMI cables are long enough to easily reach your HDMI eARC port even if it is on the side of your TV...^Ivan

### ⭐ Out of sync within hours.
*by B***L on December 23, 2022*

I hooked up the WowCast to a brand new LG tv and brand new LG sound bar and it seems to work fine. But after a couple hours of watching tv, the sound gets out of sync with the picture. You have to shut everything down and power back on then back in sync. LG support was not helpful at all with suggestions. Ultimately, I connected them with a hdmi cable and the sync issues have gone away.
