The code in the WDK should mod with the buffer size as you suggest. As it turns out, the code in the WaveRT port driver in PortCls.sys does this mod on the positions returned by the miniport's GetPosition call. With that in mind, it doesn't really matter whether or not you report linear or cyclic position values, though cyclic is consistant with the spec and consistant with the devices (HD Audio) that support position register mapping.
Thanks for the reply, Ken. I will go back and double-check. ****************** 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/
