When using the Spotify desktop version on OS 10.7.3 (started with 10.6), when playing music (streaming or local), the sound level will drop significantly. I will guess about 60-70% and then a few minutes later will return to where it was and sometimes even louder!
I've ruled out network issues, especially as it does this with local music. I've unistalled the app and reinstalled. I do not have this issue with any other apps that utilize audio. It has pretty much made the app useless on my Mac. It works flawlessly on my iOS devices :-) I have also tried toggling the "set the same volume level for all tracks" off and on with no change in behavior.
Has anyone had this problem?
