SYMPTOMS
After an application calls the Microsoft DirectSound SetSpeakerConfig method and specifies either the DSSPEAKER_7POINT1_SURROUND value or the DSSPEAKER_7POINT1_WIDE value, Sounds and Audio Devices in Control Panel does not correctly display the setting in the Speaker Setup list.

If an application specifies the DSSPEAKER_7POINT1_SURROUND value, Sounds and Audio Devices should display the description 7.1 home theater speakers. Instead, Sounds and Audio Devices incorrectly displays the description 7.1 wide configuration speakers.

If an application specifies the DSSPEAKER_7POINT1_WIDE value, Sounds and Audio Devices should display the description 7.1 wide configuration speakers. Instead, Sounds and Audio Devices incorrectly displays the description 7.1 home theater speakers.



CAUSE
This problem occurs because the DSSPEAKER_7POINT1_SURROUND value and the DSSPEAKER_7POINT1_WIDE value are mapped incorrectly when Control Panel is initialized in Microsoft Windows XP.
