Connecting the Audio-Out
(Headphone) Jack
An audio-out jack, sometimes called a
headphone
jack, connects
optional headphones or externally powered stereo speakers. An
audio-out jack is also used to connect the audio functions of an
audio/video device such as a television or VCR. The notebook is
set by default to transmit
analog
audio signals through the
audio-out (headphone) jack.
The notebook can also transmit
S/PDIF
digital audio signals
through the audio-out jacks. To transmit S/PDIF signals to
an external device, the system must include an optional docking
device.
✎
When any device is connected to an audio-out jack, the internal
speakers are disabled.
✎
When you connect a device to an audio-out jack, use only a
3.5-mm plug.
The location of the audio-out (headphone) jack varies, depending
on your notebook model.
