I am using KS and my first attempt was to leverage the KSPROPERTY_AUDIOENGINE_SUPPORTEDDEVICEFORMATS but it does not look like it returns what I was expecting From: Matthew.van.Eerde@xxxxxxxxxxxxx To: wdmaudiodev@xxxxxxxxxxxxx Subject: [wdmaudiodev] Re: Is there a way to list all supported format of an audio device Date: Fri, 16 Aug 2013 23:11:17 +0000 What API are you using to stream? If you’re using WASAPI, you can call IAudioClient2::SetClientProperties(…) and then IAudioClient::IsFormatSupported(…). If you’re using KS, you can look at the data ranges exposed by the offload pin factory. From: wdmaudiodev-bounce@xxxxxxxxxxxxx [mailto:wdmaudiodev-bounce@xxxxxxxxxxxxx] On Behalf Of Andrew Sha......
