Hi recently purchased the above, although the sound through the HDMI is very good and full, I have found the quality of sound is lacking when playing music through the Sonos app.

In order or get a decent amount of sound, the vol needs to be at around 80 (my play 5 second gen) would not need this amount of vol.

The sound is also very thin sounding with little midstage

I have  spoken to tech support online, who are unable to find any issues, just tell me to fiddle about with the EQ and suggest I telephone their support.

Anyone else come across this issue and if so what was the resolution? 
 

thanks
