• 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 1 terminal, connect a ø 3.5 mm stereo minijack cable to
the AUDIO input 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 1 terminal, connect a ø 3.5
mm stereo minijack cable to the AUDIO input terminal and set "PC Audio Select"
to "HDMI1". Page 21

audio and video are not output together even if a ø 3.5 mm stereo minijack cable is
connected to the shared AUDIO input terminal for PC IN and HDMI 1.
- Is "PC IN" selected in "PC Audio Select"? Page 21
