Mikrofon ve hoparlörün aynı ses kartından olup olmadığını nasıl kontrol edebilirim?

Question

Yeni yılınız kutlu olsun! Sorum, bir mikrofon ve bir hoparlörün Windows platformunda aynı ses kartından olup olmadığını kontrol etmektir. Farklı kartlardan geliyorlarsa, zamanlamayı ele alma mantığı farklı olacaktır. Hem DSound hem de WMME API'sini kullanıyorum. Şimdiden teşekkürler.

WMI ses kartları hakkında bazı bilgiler vermek yok. Henüz öğrenemediğim şey, onun yeterince verilip verilmediğidir. Benim laptop o Running

strComputer = "." 
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2") 
Set colItems = objWMIService.ExecQuery(_ 
    "SELECT * FROM Win32_SoundDevice",,48) 
For Each objItem in colItems

şey olur ki varsa bilmiyorum veriyor: "WMI Code Creator" Aşağıdaki komut dosyası kullanma herşey o Win32_SoundDevice nesne mağazaları listeler. Bu zor bir soru.

Answer 2

WMI'yi asla kullanmayın (burada yapacak bir şey yok) MM apis'i kullanın.

Answer 3

Girdi ve çıktı aygıtlarının kimliğine sahip olduğunuzu varsayarak, ilgili mikser kimliklerini almak için aşağıdaki gibi bir şey kullanabilirsiniz. Her ikisi de aynı ise, ikisi de aynı miksere ve muhtemelen aynı fiziksel donanımın bir parçasına eklenir. Yalnızca giriş cihazının adını varsa

/// <summary> 
    /// Get the ID of the mixer associated with the given input device ID 
    /// Returns -1 if no such mixer can be found 
    /// </summary> 
    static public int GetMixerIdInput(int inputId) 
    { 
     int mixerId = -1; 
     int result = MmeMixerApi.mixerGetID(inputId, ref mixerId, MIXER_OBJECTFLAG.WAVEIN); 
     if (((MMError)result != MMError.MMSYSERR_NOERROR) && 
      ((MMError)result != MMError.MMSYSERR_NODRIVER)) 
     { 
      throw new MmeException((MMError)result); 
     } 
     return mixerId; 
    } 

    /// <summary> 
    /// Get the ID of the mixer associated with the given output device ID 
    /// Returns -1 if no such mixer can be found 
    /// </summary> 
    static public int GetMixerIdOutput(int outputId) 
    { 
     int mixerId = -1; 
     int result = MmeMixerApi.mixerGetID(outputId, ref mixerId, MIXER_OBJECTFLAG.WAVEOUT); 
     if (((MMError)result != MMError.MMSYSERR_NOERROR) && 
      ((MMError)result != MMError.MMSYSERR_NODRIVER)) 
     { 
      throw new MmeException((MMError)result); 
     } 
     return mixerId; 
    } 

, gibi bir şey kullanabilirsiniz cihaz kimliğini bulmak için aşağıdaki:

/// <summary> 
    /// Find the ID of the input device given a name 
    /// </summary> 
    static public int GetWaveInputId(string name) 
    { 
     int id = MmeWaveApi.WAVE_MAPPER; 
     int devCount = MmeWaveApi.waveInGetNumDevs(); 
     WAVEINCAPS caps = new WAVEINCAPS(); 
     for (int dev = 0; (dev < devCount) && (id == MmeWaveApi.WAVE_MAPPER); dev++) 
     { 
      int result = MmeWaveApi.waveInGetDevCaps(dev, ref caps, Marshal.SizeOf(caps)); 
      if ((MMError)result == MMError.MMSYSERR_NOERROR) 
      { 
       if (string.Compare(name, 0, caps.szPname, 0, Math.Min(name.Length, caps.szPname.Length)) == 0) 
       { 
        id = dev; 
       } 
      } 
     } 
     return id; 
    }
