Current audio source status or other information

m_szDevDrv

Null-terminated string that contains the name of the associated device driver, for example, “DSP1:”

m_szName

Remarks

An application can get the AAM_GetSourceCap of a particular audio source and check the m_dwinfo member of that structure. If AAM_FLAG_SELECTED is set, then that audio source is active.
