However, not all HDMI cables or devices are created equal, and some may not support audio transmission or may have limited audio capabilities. To ensure that you get sound through your HDMI cable, you need to use a cable that supports audio transmission and connect it to a device that is capable of outputting audio through HDMI.

If you are experiencing no sound on your projector HDMI cable, there are several steps you can take to troubleshoot the issue. First, check the audio settings on your device to ensure that the HDMI output is set to the correct audio format. Next, check the HDMI connection to ensure that it is secure and not loose. You can also try reversing the ends of the HDMI cable or switching to a different HDMI port on your device or projector.
