Hi Hakon, Below is a post you made several months ago regarding the requirement of the reuse of MS system effects in Vista for APOs. In it, you state that the requirements for reuse go into effect in June 2007. Is that still the schedule? Also, is this a requirement for all systems and devices? For example, is a set of 3rd-party USB speakers required to implement the MS effects, or is it limited only to Vista Premium systems? If not all devices need to implement the effects, is there a document somewhere that details which devices do and do not?

Michael, Excellent questions that we can only comment on after talking with the team that owns the Vista Home Theater effects. Some of those team members are on this mailing list but some are not and the key program manager is on vacation currently. I wanted you to know that we will get back to you on the problem you are pointing out with regards to future mandatory re-use of these effects for Logo and the difficulties for IHVs in doing so. At this time it is not required until systems/devices shipping after June 2007 with grandfathering in effect for submissions made prior to June 2007.

Hakon, Thanks for the official response. I don't have a problem with IHVs having to do their own GUI for their own effects using their own property store GUIDs. What I do have a problem with is two things: 1. Not being able to reuse the Room Correction wizard without having to reuse the whole Microsoft APO property page GUI. 2. Not being able to replace the Microsoft speaker configuration GUI with the IHVs custom Bass Management/Speaker Phantoming GUI. Is either of these possible? The other features provided by the Microsoft APO have much simpler GUIs - sometimes just a simple on/off switch. Those should be quite easy to replicate in the IHVs GUI. However, the Room Correction wizard is quite complicated, as it is a complicated feature. Forcing IHVs to either use the entirety of the Microsoft APO/GUI package or replace all the functionality with their own (including Room Correction) is really putting the IHVs in a bad position. It makes their decisions on doing their own custom effects much more complicated. In light of all this, does this mean that Microsoft is going to relax its requirement about having IHVs replace all the built-in functionality? If the audio infrastructure in Vista has been defeatured, it makes sense for the IHV requirements to reflect this.
