Standard GUID for Audio types

Posted on 2007-08-07

Hi all,
   In order to work with various codec vendors, I understand that standard
guids for video formats are often derived from FOURCC code, such as H263,
H264 as shown here

and guid can be derived from it like this

GUID g2 = (GUID)FOURCCMap(FCC('H263'));
g2 outputs
0x33363248, 0x0000, 0x0010, 0x80, 0x00, 0x00, 0xaa, 0x00, 0x38, 0x9b, 0x71

But what about audio type guids? how is it derived?
How does one vendor decide what audio guid to use so it can work with other

    You are referring to

    DEFINE_GUID( GUID_DEVCLASS_SOUND, 0x4d36e97cL, 0xe325, 0x11ce, 0xbf, 0xc1, 0x08, 0x00, 0x2b, 0xe1, 0x03, 0x18 );

    (defined in 'devguid.h')
