<p id="yui_3_10_3_1_1404067672188_606">Regarding Ubuntu 14.04<br/>
Using laptop and internal speakers are working properly.<br/>
Sound card is detected.<br/>
When plugging in powered desktop computer speakers to headphone output there is no sound.<br/>
Nothing is muted, all volume is up.<br/>
Sound Settings automatically set to "play sound through headphones" when I plug speakers into headphone output.</p>
I have purged/reinstalled Pulse Audio
<p>I have purged/reinstalled ALSA.</p>
<p>Still, only internal speakers working properly.</p>
<p>When I boot up windows instead of Ubuntu, everything works fine again.<br/>
How can I track down this problem?</p>
