The test results you have selected are very old and may not represent the current state of Wine.
Selected Test Results (selected in 'Test Results' table below)
Audio playback, tagging, saving playlists, most general features.
What does not
Can't drag files onto it, you have to manually add them via the "open" button which is a pain. Unsure if it can scan your audio library for it to compile its own, might work if you put all your files in C drive? Doesn't seem to support iPod connectivity either.
What was not tested
Some more advanced features like equalisers and stuff, I see no reason why they wouldn't work though.
I gave it a Gold rating because the majority of this software works great, it's just the little things that are annoying. I would be using foobar if the drag function worked!
Admin note: rating changed to conform to the rating definitions.
The beta version of foobar2000 uses Directsound by default, which can cause some problems when playing music. In order to get the program to play music properly, you must set the Hardware Acceleration to emulate Directsound. Go to a terimal and type in "winecfg". A window will open with options for you to modify. Click on the Audio tab, and then look for "Hardware Acceleration". It is currently on "Full". Click on it, and you will have a list of options. Click on "Emulation", and then click on "Apply". foobar2000 should now be able to play music. Note that this will make foobar2000 version 0.8.3 give out an error when you try to play an audio file. Just change it back to "Full" in winecfg when you're done using foobar2000 version 0.9 beta.
