<div>somewhere i read that it cant be done. then how to set the
sound preferences?</div>
<div>the main thing i need to do is to shut off the internal
speakers and plug in external speakers connected with usb to
my dell inspiron 5559. or any other way to deal with the issue
of speakers that have low volume and are actually really
lousy. what i mean to say is that when i plug in the external
speakers the internal speakers just go on playing and nothing
comes out of the external speakers.</div>
<div>have been searching the web fo a long time now and getting
nowhere.</div>

<p>Though there is an ALSA component for controlling audio on
Lubuntu, it doesn't work for multiple audio devices (as I
understand it). <br>
</p>
<p>I recommend installing the pavucontrol package (and making sure
the pulseaudio package is already installed). <br>
</p>
<p>Run (from the menu) "PulseAudio Volume Control" from the "Sound
& Video" sub-menu.</p>
<p>Its "Configuration" tab should show you the audio devices you
have. <br>
</p>
<p>Then, in the "Output Devices" tab, specify the device you want to
use as the "Set as fallback" device. <br>
</p>
<p>You can also set the volume level (including above 100%, if you
need). <br>
</p>
<p>See if that helps. <br>
</p>
<p>If you have further questions, I may be able to help you from
there. <br>
</p>
<p>In my experience, in general, when you plug-in an audio cable to
the earphones connector, it turns off the internal laptop
speakers. <br>
</p>
<p>But I have seen on an older machine, where you have to select
(via PulseAudio Volume Control) whether to use the internal
speakers, or the audio out plug. <br>
