I am on W10 so after I have my video working I can right click on the speaker ICON then click on Playback Devices and select the output I want.
But and this is a biggy, if the content has DRM then it may force audio to either the speakers or protected audio paths like HDMI or optical.
I wish to use use my HP G6 2202tx as a music and video centre.
The USB output is connected to a DAC in a Marantz PM 7005 amplifier for stereo music. I also want to see the PC screen on my 4K TV. So when I connect the HDMI Cable to get the display on the TV, the USB audio output gets cut off.
How can I get video out from the HDMI Port and audio from the USB port.
