@madijay, As was posted above, I use a 2-channel DAC with Toslink input coming from my LG OLED TV. The DAC connects to my integrated amplifier. AND, yes, as posted above, please go into the TV settings and set the digital audio output to PCM. This is NOT the default setting.
I also use my TiVo remote to control the volume on the amplifier. I had to search for a code on the TiVo remote so that the remote controls the volume on my amplifier. This combination works perfectly.
MY single TiVo remote controls the cable box (channel selection, TiVo functions, etc.) and the amplifier volume control.
