--- Comment #17 from Justin Soulia rockinup1231@gmail.com 2011-09-10 09:29:15 CDT --- Okay, I retested this (this time using wine-1.3.28) by listening to the demo track in Windows 7 and again, the same demo track through Wine. They sound completely identical, with no elements missing from the song.
Also, I opened up regedit in wine and found the vorbis driver registered at HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Drivers32.
And for extra insurance, I started a new project in FL (in wine), and inserted an audio clip instrument that plays back an ogg-encoded track stored on my computer. It played the track through just fine.
Again, it seems fixed to me.
