I`ve installed Linux Mint a week ago, and today i found out, that only one device can use my soundcard at a time. So if i run xmms and play music - there aren`t any sounds at skype, if i watch a movie in a Totem and try to run xmms it says:
" Please check that:
Your soundcard is configured properly
You have the correct output plugin selected
No other program is blocking the soundcard"
and also i don`t hear any sounds in skype.
i`ve tried to switch plugins in "Preferences --> Sound", but when i press "test" it says: "audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink profile=music: Could not open audio device for playback. Device is being used by another application."
