Review on 🔌 AVMTON Aluminum 4K 60Hz HDMI Audio Extractor Converter: HDMI to HDMI Optical TOSLINK SPDIF+3.5MM Output, Supports HDMI 2.0 HDCP 2.2, Dolby Digital/DTS Passthrough, CEC, HDR10 by David Ross

Was very happy with this because my external desktop has no sound and I had to connect my laptop to a speaker. This product worked great until one day it just stopped working. For context, there was a power outage and the sound just wouldn't come back (although the HDMI connection to the desktop still worked). I've tried everything: toggling cables, toggling between audio switches, disconnecting and reconnecting, etc., nothing worked. The only thing I noticed was that it seemed like there was something loose in there, like shaking a broken lightbulb. I contacted Revain customer service and was able to get my money back. I will try again as this one broke quickly. :(
