Before you start ritual exorcisms, have you checked you are using the correct 3.5mm jack and it is inserted properly? See below: Jacks have a TS, or TRS, TRRS, or TRRRS contacts arrangement, depending on the connectivity they are meant to offer - mono, stereo, stereo+mic and whether this is balanced or unbalanced. Once I plugged in earphones (earbuds) with a 3.5mm jack in a MoBo and ended up with my ears getting uncomfortably warm in seconds. Whatever voltage that MoBo was applying to the 3.5mm socket was far too high. The earphones were fried while I was scratching my head trying to understand how could this have happened. I made a mental note never to trust the thin clients provided by my employer. Some times the construction of the spring loaded contacts in a plug is so poor, a correctly inserted jack does not provide a good and reliable electrical contact. I'm running a desktop presently where I have to be careful how far in I push a 3.5mm stereo jack, to be able to obtain both stereo channels audio from the speakers. Annoying as this is, I have to fettle with the jack to find the exact position at which I am able to get audio from both channels without distortion. Despite the above mishaps I generally opt for a cable rather than BT for audio. YMMV. --nextPart3669238.kQq0lBPeGt Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part.
