Connecting speakers to PC

[Carter Eggen]

I'm told that connecting and/or disconnecting the speakers from the PC
w/o turning off the PC first could injure the PC or the speakers. Any
comment? Thanks.

Unless the speakers, powered, are shorted/broken to start with, there is
no problem and will not damage either.

================================================
Personally, I do not think connecting / disconnecting speakers
while the system is running is a good idea but some users would
disagree...have a look at the following article:

What's hot-swappable or can be unplugged while computer is on?

Yes, there is a "small" chance to damage the speakers. But, there is
also a chance to damage the speaker out jack and the sound card. The
audio cable has power and this power is just enough to possibly send a
"power spike" (too much power) or a "power brownout" (too little
power.) These "fluctuations" can be enough to "burn" the sound card
audio processor / jack.

And they will laugh at you for your complaint. Every complaint I've
filed against you PCBUTTS has been for a violation of the TOS from your
posting service. I've not violated my TOS/AUP once.

As you can see, PCBUTTS continues to violate his TOS/AUP for malicious
reasons. The headers show that the above was not posted by myself and
that he's clearly violating his TOS/AUP.

Complaint filed with (e-mail address removed), including headers.

It is the same as if you were removing speakers from any device (iPod /
transistor radio). When 'unknown' says that the audio cable has 'power' the
moment you unplug it has none. Unless you use PC speakers with built-in
amplification, but then, the voltages are so small (> 10ma) that a
'brown-out' is not something that is going to happen.

I didn't say that!

I quoted you as saying that "the cable has power" and you did indeed say
just that.

Turn down the volume control on the computer speakers, before pulling
the plug. If you don't, you'd get a loud popping sound, which may
not be good for the speaker cones. Or alternately, make sure
the amplified computer speakers are turned off, so that the popping
will not be amplified.

The sound card itself should not care. As long as the operation of
plugging or unplugging, is not shorting out the card's output,
I don't see a reason why it would care.

You just like the sound of your own voice - let me explain this simply for
you - you rude hazzard - THE POST BY 'UNKNOWN' SAID "Yes, there is a "small"
chance....<clipped>.....The audio cable has power and.....<clipped>"

Baloney yourself. I have worked on a PC where the unplugging /
plugging of the speaker jack "burnt" the sound card. Whenever a
"powered" device (powered speakers) there is a small chance that the
power / ground is not correct.

 

[Tim Meddick]

Everyone seems to assume the speakers are powered (inbuilt amplification)
ones, when many are not. I don't think there's ANY risk in unplugging
unpowered speakers and a small (tiny) chance of damage with powered ones.
However, there's USB speakers around now, which should be certified as
'Hot Swap' and actually meant to be unpluggable while the PC is still on.

I've been working with computer hardware since the 70's, and in all
those years, thousands of systems, I've never seen a properly working PC
Speaker system harm a computer/sound card by changing the plug (in/out)
while the computer was in use/operation. I'm not saying that it can't
happen, I'm saying that unless the speaker / sound card is defective, it
won't harm the computer/speakers. I have seen people plug 4/8Ohms
speakers into sound cards that were not designed for them and damage the
sound card amp.

Then it was wired wrong and THAT is the cause, not the plugging and
unplugging.

Sorry but I most certainly did NOT say, type, or indicate that.
