On www.youtube.com
I watch a video and then I select another video!
The sound somehow automaticly changes to SPDIF Interface!
When ever it changes it will never send sounds to my speaker!
Question one =
How do i make it stop switching from Speakers to SPDIF Interface?
Question two =
Where happens to the sound when it is in the SPDIF Interface?
You didn't fill out the system specs and that would help someone to help you.
The sound output ("Playback") can be set in Control Panel/Hardware and Sound/Sound Panel. In the Playback section you can select the "default playback device" which is normally your speakers.
On thought, are you watching through a Video card HDMI connection? On some Video cards, there must be a connection to the PC's S/PDIF connection for the HDMI audio.
