Dear Maintainer,

when I try to play a mp3 file with mp3blaster it prints the error message
"Failed to open sound device." at the bottom line. As I am an ordinary user,
this message does not help me very much to find about what the problem might
be.

 - Is there a sound device you've tried to open?
 - If so, what's its name?
 - What might be the reasons for the failure? Permissions, ...?

Please provide as much information about the problem as possible.
