multichannel playback

multichannel playback

multichannel playback

For multichannel playback organization I use WAVEFORMATEXTENSIBLE structure. But when calling CreateSoundBuffer function
for multichannel secondary buffer creation, the function returns error "E_INVALIDARG".

What can be possible causes of this error?

System Description:
1. OS: Windows 2000;
2. Audiosystem: ADI AD1985 Sound MAX 6 channel CODEC;
3. DirectX 9.0;
4. Microsoft DirectX 9.0 SDK Summer 2004.

RE: multichannel playback

for WAVEFORMATEXTENSIBLE set wfFormat.Format.cbSize=22. I tried this and I am not getting INVALIDARG error. But on my system, I am getting only 4 channel sound. If it is working for you can you please share the sample code.
