terminal, check the "Audio Select" setting.
• 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

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 IN terminal and set "Audio Select"

to "HDMI+Analog".

Connect a Ø 3.5 mm stereo mini jack cable to listen to the audio.
- Is HDMI 1 being used? When the TV is connected to another HDMI 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 1.
- Check the "Audio Select" setting. Set "Audio Select" to "HDMI+Analog".
