Sony PCV-RZ49G - Manual (Page 335)

I cannot hear the music that is playing
There are several possible reasons why you have no sound. Try the following:
1. C heck that the volume is not turned down too low by turning up the volume (press the VOL+ button on the remote).
2. C heck whether the sound has been muted (press the MUTE button on the remote).
3. C heck that your speakers are plugged in and working correctly. Also make sure that the speaker volume knob is not turned down
all the way.
4. C heck whether the Microsoft Windows system volume needs adjustment. For more information about adjusting the system
volume, go to
Volume settings in Media C enter .
