What should I do if there is no sound from the connected audio system?

• Make sure an audio system has been connected to your VAIO computer properly.

• Use HDMI Settings / HDMI Setup to activate the “Control for HDMI” function, when you use the HDMI connection.

• Set Speakers to Audio System in the Sound Adjustments/Sound setting.

• Check the settings and the compatibility of the audio signal from the connected audio system.
