Hi, I have an Epson projector with no audio out. So I got an audio extractor and hooked it up. So I have my projector going to an audio extractor via HDMI, the audio extractor goes to my amplifier which connects my speakers. But now I have an annoying problem. When I use the remote for the projector to adjust the volume it does not adjust my speakers volume. To adjust my speakers volume I have to physically turn the knob on my amplifier. Is there any way to sync the two volumes together?
