I have an HDMI cable connected from a desktop to my TV. This brings the video correctly, but have run RCA cables from back of TV's audio output to Aux. input of Home theater for sound. It has been working fine with some adjustments in settings of Windows 10 to stereo mix so still can use computer speakers. Now the sound is not working. Have checked the settings and nothing has changed. Sony TV is showing in sound settings, set to communications stereo mix. When I send a test to the speakers, the sound is heard on the TV. Do you think it has anything to do with Windows 10 updates and how do I fix it?
