headphone jack not muting speakers reliably
Posted: Sun Aug 23, 2009 9:05 pm
My problem T61 (see my other thread) has developped yet another issue: more often than not, plugging headphones doens't mute the speakers. Sometimes the speakers will cut in and out on the slightest movement, indicating a mechanical issue with the jack (IMO).
At first I thought I was hearing things and then I used a headphone that's not sensitive and the problem became clear as day: both headphones and speakers were playing at the same time.
Does anyone know a fix for this short of changing the motherboard?
Perhaps someone knows about a mechanical trick such as using a particular adapter that's slightly larger than the norm.
Failing that, is there a way to manually mute the speakers in software or, even better, to turn their volume down a bit relative to the headphone voltage? I guess my only other alternatives would be to use an external souncard for headphones or to stick with very sensitive closed headphones in public.
