• Check the audio output of the connected external equipment. Is the volume too

• When external equipment is connected via an HDMI cable, you may need to
configure the audio to be output through the HDMI cable.
• When audio is not output from external equipment connected to the PC IN or HDMI
1 terminal, check the "Audio Select" setting.
• Even when external equipment is connected using an HDMI-certified 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-certified
cable to the HDMI 1 terminal, connect a Ø 3.5 mm stereo mini jack cable to the
AUDIO IN terminal and set "Audio Select" to "HDMI+Analog".
• When connecting a PC via an HDMI-certified cable, check the following:
- Is the audio output of the PC configured 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-certified cable to the HDMI 1 terminal, connect a
Ø 3.5 mm stereo mini jack cable to the AUDIO IN terminal and set "Audio Select"
to "HDMI+Analog". Page 28
• 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 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 mini jack 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".
