Description

Why does the product not work? It is not compatible with 5.1-channel signals like Dolby AC3, please adjust the audio output to PCM before use. Setting Step: Home page→System setting→Picture and sound→Voice setting→Digital audio output - PCM. Why is there noise? Try using a separate 5V-USB power supply to power the DAC converter. Why is there no sound when using this audio converter? This product is a one-way audio converter, and the audio signal can only be transmitted to the device with a 3.5MM jack via optical fiber. Why is the volume not adjustable? This product is connected to the audio system via an optical fiber interface, so the volume cannot be adjusted via the remote control. Please adjust the volume on the device connected to the AUX interface.

This does what I need it to do, which is transmit audio. So I'm pleased with it.

  • Saved my old surround sound system, make sure you use a power adapter
Size: 5FT Number of Items: 1
Bought new expensive big TV, realized I used Aux for the surround sound system all these years. My system is old, it doesn't have all those fancy optical/hdmi ports. So bought this to try make the optical on the back of the TV to work with the Aux. Worked pretty good. But do make sure you get a small 5V 1A power adapter, I used the usb port on the back of the tv and keeps getting these pop noise a few mins after shutting of tv, turned out the usb power is stopped once tv is off so that's why the pop noise. Got an old charger and plugged it in, never had problem again with the pop noise. The cable from optical port to the Aux port is pretty short, like 5in? something like that, but they did inlcude a extension cable for the aux, that's a plus. ... show more

  • Replaced Bluetooth headphones
Size: 5FT Number of Items: 1
It was perfection. It allowed me to use my favorite plug in Sennheiser on ear headrest by using the optical plug. There was no standard headphone plug on the tv I bought. Most importantly, it saved me from having to buy a Bluetooth headrest.
