By default media players get a chrome cast icon, which feels
quite wrong for my old style amplifier that doesn't have any
connection to the rest of the word, except for a RS232 port.
Some amplifiers/receivers do not report any volume (due to them not
knowing), for example NAD C 356BEE is documented to return an empty
string for volume.
At least don't crash when we get None back.
nad_receiver received a few fixes in 0.0.12, which enables the integration
for me. I assume it may depend on the receiver model, but my receiver only reports
mute state and volume when it's on, while the library used to assume to always
get a reply. With 0.0.11 the nad integration simply excepts on startup,
after bumping the version up it works.
Fixes this:
