I wonder if this is endemic to this model. It passes the Dell tests, and does not seem to
be due to the "pin" question on the jack. (The Dell forum could not log me in at the moment,
so figured I'd ask here.) When an external audio system is plugged in, that works well, but
the internal speakers produce a weak and tinny sound, unlike the speakers in an earlier
Dell laptop, an E1505, which was quite loud and useful, altho certainly not hi-fi!
Have tested with YouTube under PCLOS.
Thanx for your experience--doug
