The volume control is temporarily disabled for Spotify until we develop a proper solution for a unified volume control (that will happen soon). In the meanwhile you can use alsamixer to control volume during Spotify playback, when the spop daemon is active.
I have the same problem. For anyone that is confused by what "use alsamixer" means, it turns out you have to ssh into the Pi (use "root" as user and "rune" as the pwd), and then run "alsamixer", then press F6 to select your sound card, then right arrow to select to change volume, then the up and down arrows to change it. Phew!
Bring on the GUI volume control with Spotify !!
Or of course I could get off my lazy arse, cross the room and actual move the knob on the amp. What is this, the 90s or something?!
