Hi All, How can I implement an audio driver (WavePCI/WaveRT) for Windows Vista that - has a device with more than 8 channels (> 7.1) and - can be accessed via DirectSound with more than 8 channels?Under Windows XP this is no problem, it works up to 24 channels without any problem.
Under Windows Vista a device :- with a "KSNODETYPE_SPEAKER" Endpoint is used by the audio engine via channels and channel-mask up to 7.1. even if the device can do more channels, there won't be used more than 8 channels. - with a "KSNODETYPE_LINE_CONNECTOR" is used by the audio engine via channels and channelmask=0. this works up to 30 channels (Server 2008 Beta1 : 32 channels) with the "test" button or SndRec32.exe, but DirectSound only works when configured to mono or stereo (MediaPlayer, WinAmp).
Is there anybody with a hint or a guideline or has anybody solved this issue ?
