Question Mixing Microphone and TV audios in my receiver

Hey guys,

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!

As noted on the Amazon page for that mixer that you linked to, the music source must be connected to the mixer as receivers are not designed to play two audio sources at one time.

You'll need to use an optical --> 3.5mm converter like this one ---> https://www.amazon.com/OREI-Digital-.../dp/B008EPW7TA
