My Dell Latitude 6520 is facing the following problem: sound will only play through connected headphones; no audio through speakers, once the headphones are disconnected. I have uninstalled and re-installed the sound card driver multiple times with no result. As a side note, this laptop model has been affected by the sensor in the headphones plug; people are reporting this issue, that is, although the headphones are disconnected, the sensor will detect them, disabling playback through the speakers. I gave up until today, once it happened something strange. In a Skype call, audio was playing through the speakers, although the headphone was connected! How could this magic occur? This lead to a few statements: - speakers are not damaged, they work - some configuration in the computer is spoiled, although in the sound properties->playback, the speakers are correctly set as the default playback device.... I wonder how could skype bypass eventually the headphone sensor or why Skype can successfully use the speakers while the system cannot. Any help appreciated
But how does Skype use the external speakers? – Riccardo – 2014-10-07T16:32:16.053
I have performed the diagnostic test within the BIOS. The speakers are working correctly! Must be a Window configuration problem – Riccardo – 2014-10-07T17:05:30.630
Oh well the troubleshooting guide states that it could be a fialure on the sens pin. Thanks for helping – Riccardo – 2014-10-07T17:24:53.760
Is your laptop still under warranty? If so, back your machine up and get it fixed with Dell. – Sun – 2014-10-07T18:09:55.643
No unfortunately! Not worth it to replace the motherboard. Thanks – Riccardo – 2014-10-07T18:38:51.880
