I want to select the cmSrcWaveOut, but it seem can't work, I use XP/delphi 2009 and Wave Audio Package Version 1.89:

Code: Select all

AudioMixer.DestinationID:=1;
for LineID := 0 to AudioMixer.LineCount - 1 do
    if (AudioMixer.Lines[LineID].ComponentType = cmSrcWaveOut) then
    begin
      AudioMixer.Master.SelectedLine := LineID;
    end;


Thank you.

I use "SNDVOL32.EXE /R" command to check which recording source is selected. I want to change the recording source to "Wave Out", Thanks.

Did you try cmDstWaveIn?

cmDstWaveIn can't work



I want to use TStockAudioRecorder to record the wave-out. the default recording source is cd, so I need use code to change source of sound recording, Thank you.

Use Mixer Control (SoundManager) demo to find out which control works as you expect. Then, you have to modify or debug the demo to find which ControlType you should look for.

SoundManager can't show "volumn" and "select" checkbox, why?

What do you mean "can't show"? No control at all, or what you are looking for?

I can compile and run SoundManager, but every Line "volumn" and "select" checkbox is invisible.

I have no idea what's going on.

I have attached the executable of sound manager demo. Maybe you can discover the problem using it.
