What are the dB min/max/step values being advertised by your volume node? You can right-click the slider to show dB values instead of percent. If a driver exposes KSNODETYPE_VOLUME, the initial value for that setting should be whatever the driver says it is; the OS won't override it. -----Original Message----- From: wdmaudiodev-bounce@xxxxxxxxxxxxx [mailto:wdmaudiodev-bounce@xxxxxxxxxxxxx] On Behalf Of Alexey Kachalov Sent: Thursday, December 15, 2011 8:21 AM To: wdmaudiodev@xxxxxxxxxxxxx Subject: [wdmaudiodev] Re: [SPAM] [MessageScore][alltestmode] Re: [SPAM] [Bayesian][alltestmode] Re: Disable volume control or Level tab at MSVAD Because, default volume level after driver install on different OSs is different - Seven 100%, Vista 25%. And the main reason - the same value of volume level at different OSs give different gain results. That is why i want to disable volume control to achieve the same sound on sink and source of stream.
