Recording error: "Should descend into data chunk. Please report."

[Peter Åstrand]

I have a Windows app that records from a microphone. For some reason, this 
fails. The application displays the error message "The driver cannot 
recognize the specified command", which I guess is the translation of 
MCIERR_UNRECOGNIZED_COMMAND. At the same time, Wine prints out:

fixme:mciwave:WAVE_mciRecord Should descend into data chunk. Please report.

Is this related, perhaps? I believe MCIERR_UNRECOGNIZED_COMMAND is 
returned from mci.c:MCI_ParseOptArgs. Running with WINEDEBUG=+mci gives:

trace:mci:mciSendCommandW => 00000000

(I've activated the TRACE print in MCI_ParseOptArgs.)

Any ideas?

Well, sort of. The error message is gone; MCIERR_UNRECOGNIZED_COMMAND is 
not returned any more.

However, something else is wrong: No recording file is saved. There should 
be a file called 0000.wav in the "Tal" directory, but no such file exists 
after recording. Here's the trace:

Does this look strange or normal?

Could it help with using one or several DLL files from Windows?

Included below.

(If you want to try the application yourself, it's actually available from 
http://www.softogram.se/studieknepengelskademo.html. Some parts of the 
program is in Swedish, though. After starting the program, select one book 
in the list and press the button marked with "1". Press the microphone 
button to start recording, and then the square to stop.)

the main point is that we're now opening the files readonly (for 
playback) instead of read/write, and we don't open them writable for 
record command.
