Headphones

v If you cannot hear anything, multiple speaker devices might be
attached. Find the Devices or Options section of your application
and make sure that the Lenovo USB/Analog Headset by Sennheiser
is the device being used. In USB mode, it is the "C-Media USB Sound
Device". In analog mode, it is listed as an option related to your
specific sound card.
v If you still cannot hear sound, check the volume control on the
headset cord, and make sure that it is not turned all the way down.
Set it to a mid-range position. Also, check the volume levels for
Windows Sound Manager for all devices in playback mode, and the
volume level settings (if any) for the application you are using.
Check that the headset is not muted, and that all sound levels are at
50%. When you start to hear sound, these settings can be adjusted to
comfortable levels.
