[Stk] DirectSound on Windows 7?

[Nick]

Hi Joseph,
 
Thanks that was helpful and it now works.
 
Now I have a different question. When I create a pure sine wave with the sine example in the projects folder, I noticed that the frequency that when playing it back throught he dac-> tick, I get a slightly different frequency that is played back than when it is played back through the Windows Media player as a wave file. Could it be that somehow the sampling frequency information is not being correctly put into the wave file?  
 
It is noticable, the dac->tick plays the A 440 (at 48 KHz sampling) a whole tone lower than the A 440 which plays back through Windows Media player when I generate the wave file.
 
Any ideas what I'm doing wrong?
 
Thanks,
Nick

It sounds like you're just not telling the compiler to link the right thing.  If it were a matter of the library not being supported, you would be told that the library wasn't there, or you'd get an error before linking.  Open properties for the project and go to
Configuration Properties > Linker > Input and make sure that Dsound.lib is there.
If it is already there, then perhaps, somehow, your WinDef.h is confused and so the WINAPI macro is defined wrong when you include <dsound.h> and consequently the function signature doesn't match the one found in dsound.lib.

Hi,
I'm having trouble with the following cpp files:
RtAudio
RTMidi
RtWvIn
RtWvOut
 
which I understand make use of DirectSound API in Windows. Since I'm running Windows 7 on a 64 bit laptop, I'm wondering if the reason these files are failing to link is because DirectSound is no longer supported on Win 7?
 
I do have the preprocessor directive _WINDOWS_DS_   specified on the C++ command line build argument with Visual Studio 2010.
 
Errors from the compile are shown below.
 
Thanks,
Nick
