--- Comment #1 from Jörg Höhle hoehle@users.sourceforge.net 2009-10-01 11:24:43 --- Created an attachment (id=23868) --> (http://bugs.winehq.org/attachment.cgi?id=23868) winmm/tests/mci.c testcase work-in-progress
The MSDN example that breaks Wine is at http://msdn.microsoft.com/en-us/library/dd798631(VS.85).aspx Recording with a Waveform-Audio Device
The test should create a tempfile.wav of 2 seconds exactly. If you have no microphone (I haven't), it'll record 2 seconds of (near) silence.
