Hi everyone, so far I have only streamed 16bit stuff over WDM-KS and I now want to also support 24bit. If I have a KS-WDM- device which tells me that it supports 24bit (only and not 32bit), can I still stream 32bit values to the driver, or do I need to pack stuff into 24bit units? I would think, that if I use WAVEFORMATEXTENSIBLE and set wValidBitsPerSample to 24, I should be able to still stream 32bits to the device - or have I got it wrong there? Also - what about USB 1.1 devices? would the USBAUDIO.SYS shrink the data to 24bit before transmission before it is sent over the interface (this would obviously save precious bandwitdth) Tobias -- TE-SYSTEMS GmbH - competence in e-communications.
