I reinstalled the Spotify app on my iPhone, but it did not make any difference. It actually happens quite frequently, and the worst part is that often when I hit the connect button the current track actually starts playing (with max volume), even if the track was paused before. Here's what I now always do to avoid being blasted:
MUTE my receiver
in the app go to the Connect page and connect to my receiver (which often starts playing the current track at max volume)
go back to Now Playing and pause the track (if I would just lower the volume while playing it would unmute my receiver and I would still get blasted)
go back to Connect page and lower the volume
go back to Now Playing and resume the track
UNMUTE my receiver
This is the only 'safe' way for me to operate the Spotify app - thats just nuts!! Does official Spotify support monitor these forums, or do I have to open a separate support request?
I have the same problems. first with the combination of IPd mini and spotify to BeoplayS9 of B&O. Today I had the same problem with my !acbook Pro and Itunes with Airplay. My conclusion is that it is not spotify problem. That doesnt mak it any better, what is the use of spotify when these things happen? I will go back to the store tomorrow and say this technology isnt mature yet, please take my B&O back.
why wouldn't it be a Spotify problem? It's the Spotify connect code that somehow submits a command to my receiver to set the volume to max. Now, maybe it turns out to be a flaw on the receiver side that spotify doesn't have any control over (very unlikely though, since it seems to happen on at least two totally unrelated receiver hardware). But even then Spotify connect could provide an option to disable the volume sync completely (my Yamaha has this option for AirPlay) - I wouldn't mind missing the volume change functionality (which I don't use anyways) if this would allow me to use the spotify app without having to worry each time...
