We bought this Microphone system
but we're having problems mixing Chromecast's audio with the Microphone system's audio in the Receiver.
Receiver is Onkyo, model HT-R390 Receiver's Manual
- The Microphone system is connected to the Receiver via RCA cable to DVR/VCR IN
- The TV is connected to the Receiver via Optical Cable
- Chromecast is connected to the TV's HDMI (for Karaoke Music)
I enabled the DVR/VCR channel on the Receiver and I only get audio from the Chromecast/TV, and when I disconnect the TV's Optical cable from the Receiver, only then do I get the audio from the Microphone System, but how do I get them to work together?
These are the ports on the Microphone system:
The TV doesn't have a 3.5" audio out, otherwise I would have connected it to the Microphone System.
Is there some setting on the Receiver that I am missing? Or do I need to buy some additional audio hardware? I heard of Audio Mixers but I couldn't find one that mixes Optical with RCA.
Hopefully someone can help me out.
Thanks in advance!
