I do not think you need it if you only implement the standard streaming interface.
I needed it because I was adding support for Dolby Digital over S/PDIF. If you want to support that using DirectSound, then you need to implement the looped streaming interface, which requires the audio position property. 

I also needed it to support Sonar.

I wonder if this is necessary if you only implement a KSINTERFACE_STANDARD_STREAMING stream. 

The avssamp does not expose this. Is this really necessary?

Thanks.
