I have the same annoying problem with the volume button lagging when I turn Spotify on with my Thinkpad T410.
It started after Spotify had been automatically updated.
Besides It seems that my pc becomes significantly slower for a period (5 min) when the application is opened. This should not happen on a i7 with such a small app. This also started occurring after the latest update.
I hope these issues will be taken care of soon by the Spotify team.
Just had an experiment with my volume controls on my keyboard.
Normally if I press and hold them, it continuously adjusts the volume (without noticable stepping).
This is what happens when Spotify is not in focus.
When Spotify is in focus: I press and hold, it moves only one step and stops. If I then press the key again, it'll move another step but no more. It seems Spotify takes the key holding action to mean one step only, regardless of how long its held. While Windows natively takes the key holding action to mean continously adjust until the key is released.
Really this ought to be sorted!!
(Just in case it's OS dependant: Windows 7 Professional x64)
-- First was the record, then the cassette, the CD, then came along Spotify... that really did change everything!
I too have experienced this problem, on my girlfriends Sony Vaio (laptop), on my dell latitude E6410, (both using the in-built volume up/down keys, and when plugging in a keyboard through a docking station), and also on my PC (Windows 64bit). However my play/pause/next/previous keys work however.
This has been a 'feature' for as long as I can remember since beginning to use the service (on my Toshiba laptop), but I've just got used to Alt-Tab > Volume change > Alt-Tab. It's funny what lengths people (I) will go to to get around features rather than trying to report/fix them :smileywink:.
