I have chromecast generation 3 device connected it with multimedia projector through HDMI port. I am using chrome explorer in laptop and pc to chromecast my screen. The problem is chromecast use multimedia projector speakers for audio output which is very slow in volume. How can I use my PC or laptop or phone audio for high volume output?
When you share your desktop entire screen to chromecast device from google chrome browser uncheck audio share option. This way you will use your laptop pc or phone audio output.
