From: Rados3aw Michalski on 17 Oct 2005 17:02 Hallo I comipile and install MSVAD simple driver from DDK samples. But there is something strange in it. When I use SndVol32 program I can change volum and mute lines only for rendrering pins. When I go to record devices tabs I can select msvad from list, but it hasn't any visible lines and controls. I topology it has microphone pin connected to volume control node and to mux node. What I must add do "simple" driver to see volume control for microphone ??? thx for help Radek from Poland

Also, topology setup is very finicky, and everything must be done exactly right (check the other DDK samples except msvad, like the ac97 sample). Be sure to look at the topology using ksstudio. It would help if you had a working card whose topology you could view with ksstudio. Try subscribing to wdmaudiodev on www.freelists.org and asking there, it's dedicated to WDM audio. Philip Lukidis

In KSStudio in KSCATEGORY_AUDIO_DEVICE I see only topology from Wave miniport driver (only ADC node) with 2 additional nodes: supermix and Sample Rate Converter. I In KS_CATEGORY_AUDIO I can sellect both miniport wave and topolgy. And in this filter I can see all my nodes with right connection. KSStudio has no problems when it works with my sound cards. (3 sounds card on 3 PC). It maps topology properly and display recording source pins/line. But i havn't sorce code for this drivers. thx for url > Try subscribing to wdmaudiodev on www.freelists.org and asking there, it's > dedicated to WDM audio. > > Philip Lukidis > > |
