I was messing around in my Audio managaer EQing and such and clicked Set as default device??. Anyways all of a sudden my sound stopped!! I can see the song playing and everything but nothing comes out the speakers. I am using Windows 7 with a realtek HD audio manager running HDMI out to TV. Can anyone help?
Right click on the sound icon located in the system tray, choose Playback devices, select the TV as the playback device and set it as default. This should normally get your sound working again.
