  [out] IMFAttributes **ppAttrs
);

Parameters

[out] ppAttrs

Receives a pointer to the IMFAttributes interface of the attribute store containing the current audio stream settings. Caller must release the interface pointer.

Return value

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
