Selected Test Results (selected in 'Test Results' table below)
Almost all, but playback is very buggy.
What does not
Main things - playback very often breaks and volume control doesn't work at all (always at maximum).
Looks like Wine audio server breaks at some point (looks like at 100% system load) and produces very lacerated or ragged playback that hangs after all, sometimes relaunching foobar2000 fix it, sometimes not (than even testing sound in Wine config sounds ragged).
What was not tested
Was tested everything.
Maybe playback problems somehow related with high input/output audio frequency (like 192 kHz) and BPS (bits per sample) like 24 or 32.

stuttering audio in foobar2000 since Wine 1.4
by Mr. Gil on Thursday October 11th 2012, 13:21
I've noticed when I'm tagging files or using foobar2000 to copy or move music files from one place to another that the audio starts skipping with gaps of silence in the music. My Debian-based distro currently offers Wine 1.4.1, and I compiled Wine 1.5.14 just now, and both have this issue. I then tried compiling Wine 1.2 and all the skipping went away. I tried foobar2000 v1.1.9, 1.1.11. 1.1.14 and 1.1.15 and they all behaved the same. Only reverting to an old version of Wine fixed the problem. I wonder what happened in Wine to cause foobar2000's audio to become discontinuous when there is heavy disk activity.
Playing column glitched
by Mateusz on Thursday May 24th 2012, 12:49
After maximizing from a smaller window, the "Playing" column in the default UI is covered by a gray rectangle. The size of rectangle depends on how small the window was before maximizing, and it disappears after minimizing/unminimizing the window.
fixing grainy album art
by Mr. Gil on Tuesday March 20th 2012, 14:00
Every time I install foobar2000 on a new Linux system, the album art looks grainy, fuzzy, mottled, crosshatched with artifacts, 256-color, etc. I'm putting a bunch of possible keywords here because when I searched for this I found nothing.
The fix is to place the native Windows version of gdiplus.dll in the ~/.wine/drive_c/windows/system32 directory. gdiplus.dll can be downloaded from the web.
Maybe newer versions of Wine have better gdiplus functionality by now, but a typical distro repository may still be on Wine 1.0.1.
"DarkOne" theme fix
by Jonathan Busby on Wednesday December 16th 2009, 12:23
Most of what is broken when the "DarkOne" v1.6 theme is installed can be fixed by a DLL override. Specifically, overriding the built-in jscript.dll with a native3 Windows XP SP3 Windows/system32/jscript.dll
seems to do the trick.
