Connecting older pioneer receiver to Vizio HDTV

Mar 6, 2018
I have tried connecting Vizio M50-C1 TV via a digital audio cable through a digital to analog audio converter to my old Pioneer SX 2600 receiver. The options available on the receiver to plug the red & white audio cables into are 1)VCR 2)Tape/DAT 3)Tape 2.
No luck using any of these. No sound from SONYSS-CS3 floor speakers.
I have limited knowledge in this area.
You may have to turn the digital output on, the TV speakers off, and change the audio output type to PCM stereo in the TV audio menu to get it working. Check the TV manual for details.
