Hi,
Earlier when I connected my HD LG TV to my notebook using HDMI, the audio and video got transfered to the TV. At that time, the LG TV was visible as an audio playback device in the 'Sound' option. By mistake, I deactivated the LG TV and it vanished from the playback devices in 'Sound'. I again connected the TV and restarted the laptop but the TV audio playback device has not reappeared. Request inputs from anyone who has faced this issue. The laptop came with Win 8 pre-installed and I later got it upgraded to Win 8.1.
Regards
Roy
