I have a speaker plug malfunctioning on a Toshiba laptop.
When the earphones or speaker is disconnected it doesn't make a clean
contact to revert back to the inbuilt speakers.
It will work with MUCH fiddling........ for a few seconds on & off......
Will it hurt to make a small solder bridge to enable L & R inbuilt speakers
at the same time as the external ones?
I realise I can get new ones etc but thought if no damage doing it my
way...... why not?
I can easily do the bridge on the reverse side & hence no need to remove
faulty connector.
Opinions please?

There are two ways that this could work; either the amplifier "power
output" is switched between the headphones and the speakers, or there is
a logic signal that shuts off the speakers (and amplifier) when the
headphones are plugged in. In the former situation, you might be
putting the headphones and the speakers in parallel. The impedance of
the speakers may be so low compared to the headphones that the
headphones effectively get little power (almost no volume), but either
way, it is very unlikely to do any actual damage. The real issue is
that most people want the speakers to shut off when the headphones are
plugged in.

Solder bridge should do OK, and I don't think two many issues trying to
use both headphones and speaker at the same time.

Though, If you have a spare USB port, you can get a very cheap USB sound
adaptor and use that for your headphones.

Thankyou for the replies.
I'm mostly wanting the laptop speakers to work as 99.9% of the time no-one
uses the plug in sockets anyway. (in my experience)
With the solder I'll "force" the onboard speakers into action 100% of the
time & both if anything does get plugged in.
Once again.... thankyou!
