I found the following the other day: http://blogs.msdn.com/larryosterman/archive/2005/09/23/473351.aspx Looks like the whole audio subsystem has been completely re-written and is now in user-space. Wow. Does anybody know of any official info from Microsoft on this?. I had heard (I think here) that Vista will only show one "mixer" per audio device, vs. XP showing one mixer per waveIn/Out. This seems quite a change. Is it documented anyware?. (I must admit I have not been through the latest Vista DDK looking for this type of info) -steve ------------------------ Stephen Turner AudioScience, Inc. www.audioscience.com ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.com/
