- Check if the corresponding “HDMI Out 2” port is outputting sound. If not, you need to check if there is any sound transmitted from the input source.
- If there is sound from “HDMI output 2” port, try setting the corresponding input source’s audio format to PCM or DD 5.1.
- Check if you have connected the corresponding “HDMI Out 2” port to the TV via its HDMI ARC port.
- Check if you have selected an external device as the TV’s speaker.
- Try setting the TV’s audio format to PCM or DD 5.1.
- Check if your soundbar has an extra independent HDMI input port, in addition to the common HDMI ARC port. If it has one, you can try connecting to this independent HDMI input port. If it doesn’t have one, you can connect your TV to the “HDMI Out 2” port first, then connect the soundbar to the TV via HDMI ARC port. Please don’t connect the soundbar to the matrix switch directly via HDMI ARC port, as this port can only be connected to a TV.
- Please note that the matrix switch, through its “HDMI Out 2” port, can only output HDMI (both audio and video) signal to the soundbar, but cannot output HDMI ARC signal to the soundbar.
- This is how the matrix switch’s HDMI ARC function works: The TV connected to the “HDMI Out 2” port returns audio back to the matrix switch via HDMI ARC, then the audio can be de-emdeded to the S/PDIF output port.
- Check if the corresponding input source has been switched to the corresponding output port.
- Try restarting the matrix switch to check if it helps.
- Check your HDMI cables, or use new cables.
- Try connecting the source to the display device directly, without using the matrix switch. Then check if there is any video output.
- Swap the HDMI cables for the two output ports to check if it helps.
- Set the input source’s resolution to 1080P.
- Check if the corresponding “HDMI Out 1” port is outputting sound. If not, you need to check if there is any sound transmitted from the input source.
- If there is sound from “HDMI output 1” port, try setting the corresponding input source’s audio format to “PCM”.
- Check if the battery has run out of power.
- Check if the battery is installed correctly and on the right position.
- When you use the remote controller, it needs to be directly facing the IR receiving window on the front panel of the matrix switch.
- Try using a pin to press the “System Code Switch” button on the bottom right corner of the remote controller to modify the IR system code.
- Please note that the ON/OFF buttons on the remote controller are used to control the on/off of the two connected TVs, instead of the matrix switch itself.
- Check if the connection method of the RS232 cable between the matrix switch and the control PC/system is correct. It should be “TX-RX, RX-TX, GND-GND”.
- Try restarting the matrix switch to check if you can receive restarting feedback from the device. In this way, you can check if the RS232 settings are correct.
- Check if you can add the terminators “CR”and “NL” in the command sender.
- Ensure you have inputted the correct command.
