timestamping in AUHal renderer

I still don't have this working.
Can anyone explain me how I retrieve the time at which my sample will be rendered by the auhal renderer?
I need to provide this time to my VLC audio layer in order to get the right sample from the vlc core. This was possible in CoreAudio by using outTimestamp, but I don't see a similar method for AUHAL.
If getting the rendertime is impossible, then perhaps it's possible to get the render delay instead? VLC simply refuses if I ask for samples for the current time, or one in the past. It wants a proper rendertime.


I'm very committed to getting discrete multichannel audio output working _properly_ in VLC (which would make us the first free application to do so I believe), but I'm finding it very difficult to getting any good documentation and support on this particular subject. Audio just isn't my specialty, so you will have to cut me some slack.
