Im using BT4 using external harddrive. I have spotify in windows, so I wanted it also to linux. it works well in Wine, but I noticed, that the is some problems with soundcard. My laptop HP pavilion dv7-2050eo has 3 speakers and 2 headset outputs. Now all sound comes from one speaker.
Re: Sound device
Have you tried running winecfg and making sure ALSA is checked?
That is the only thing that I know to do for that. I dont personally use that program but I did a quick google search on it and there are tons of different threads stating there are lots of different issues using this program through wine. Hope this helps you out some.
