Agreed with the observations above.
How about this for an example.
A couple of years ago bought an OLED TV. As our “old” AV processor is not HDMI 2 compatible, the only audio connection solution for streamed movies was therefore limited by SPDIF, and as such DD or DTS at best.
I’ve recently bought a HDMI audio extractor, which can be plugged into the ARC output from my TV and send uncompressed audio via HDMI into our processor.
The only downside is that the volume control doesn’t work with the TV, ie you need to also use the remote for the processor. Despite the benefits, o get a bunch of ear ache from the missus ref the remote, who’s insisted that she only uses the SPDIF connection
