LG WTP3 WOWCAST Wireless Audio Transmitter for TV to Soundbar Wireless Connection

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.

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.

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.

빨리받아서 설치완료.

Had to restart a few times, but works fine 99% of time. Powered off of USB port on TV.

Works great with my LG C1 tv and LG SC9S sound bar, I was able to finally have a wireless setup between my tv and soundbar without having to use a 2.1 hdmi cable. Haven't had any issues with connectivity.

Couldn't be easier. I bought this for use with a new LG 83" OLED C3 and S80QY sound bar (and rear speaker kit) to eliminate a HDMI cable from TV to sound bar. Plugged it into the TV, went to (sound bar) settings on the TV and chose "E-ARC" and the sound bar flashed "Wowcast" on its display immediately and the sound was back. Easy peasy. Why LG doesn't BUILD THIS DEVICE INTO THEIR TVs IS A MYSTERY. The only side effect I can see is that a message appears on the bottom of the TV for 5 seconds when you turn on the TV, saying "soundbar is now connected."

Bought this with the LG S95QR sound bar and wireless speakers to hook up to a new LG OLED TV. Connected seemlessly and I thought we were onto a winner. After a short time we started getting loud cracks coming from the speakers. Some sort of static. It got so frequent and loud we've disconnected this piece of junk and hard wired the sound system. The sound system is another whole story and there's a YT review which I'd wished I had seen before considering my purchase of both of these. Long and short is LG make great TV's, sound systems and wireless connections, not so much
