Chromecast DSP volume

Chromecast thank you!!! I didn’t even realize this was coming so nice surprise.

couple minor points

Doesn’t seem to support DSP volume but only device volume via the chromecast audio… would there be any difference in quality?

Also when using home group and reducing volume the “bit perfect” light on “now playing” is lit although perhaps shouldn’t be.

Q… would there be any difference in quality between Chromecast audio optical out…previously using Mac mini optical out or USB to chord qutest DAC.

Thank you again it works perfectly so far
