•When audio is not output from external equipment connected to the PC IN or HDMI IN 1 terminal, check the "PC Audio Select" setting. Page 21

•Even when external equipment is connected using an HDMI-certifi ed cable, an audio cable connection may be required depending on the type of equipment and the media being played back. In this case, in addition to connecting an HDMI-certifi ed cable to the HDMI IN 1 terminal, connect a ø 3.5 mm stereo minijack cable to the AUDIO IN terminal and set "PC Audio Select" to "HDMI1". Page 21

•When connecting a PC via an HDMI-certifi ed cable, check the following:

-Is the audio output of the PC confi gured correctly? Check the audio output settings and output audio format in Sound Properties on the PC.

Only PCM format audio can be output. Compressed audio (with a sampling rate of 32kHz, 44.1kHz, or 48kHz) and DTS format audio cannot be output.

-Depending on the board, only video signals may be output. In this case, in addition to connecting an HDMI-certifi ed cable to the HDMI IN 1 terminal, connect a ø 3.5 mm stereo minijack cable to the AUDIO IN terminal and set "PC Audio Select" to "HDMI1". Page 21

•If you are using a DVI-HDMI conversion cable to connect external equipment to the TV, check the following:

-Is an audio cable connected? The DVI-HDMI conversion cable is for video only. Connect a ø 3.5 mm stereo minijack cable to listen to the audio.

-Is HDMI IN 1 being used? When the TV is connected to another HDMI IN terminal, the audio and video are not output together even if a ø 3.5 mm stereo minijack cable is connected to the shared AUDIO IN terminal for PC IN and HDMI IN 1.

-Is "PC IN" selected in "PC Audio Select"? Page 21
