For various reasons (see bottom of WinePulse – PulseAudio for Wine) the main branch of Wine does not support PulseAudio. This makes Spotify under Wine misbehave a bit, but fortunately there is a solution! A person called Neil Wilson has been kind enough to provide PPA packages of Wine with the WinePulse patch. I’m installning this PPA on all my Ubuntu machines where me of my wife use Spotify.
