does length of wire measurably affect time required for audio signal to travel from one end of wire to other?

Theoretically, electrons move at the speed of light. To measure accurately a delay of 1 ms would require two wires, each 93 miles long.

With no signal loss, you use zero cable.  But in answer to your question, lengths of up to ten meters coupled to an appropriate antenna would still be applicable.  A quick search yields:\n\n"30 meters of new 75 Ohm hardline has only about 3.77 dB loss at 2 GHz"

No equations but this may help.... when an electrical signal is travelling along, for example a piece of copper wire, there will be a field generated aroung the cable, similar to that of a magnet (remember at school we were taught about magnetic fields  with a magnet piece of paper and iron filings)\nWhen a second piece of wire is brought in close proximity to the 1st piece then it will cut the field , and a signal will be induced into the second piece of wire.This is called mutual induction. If a signal is now added to the second wire then the induced signal will either add or detract from it dependant on the phase at the time.... this will happen, also within the 1st piece of wire, as a field is now being generated by a signal supplied to the second wire.\nNow, by twisting the pairs together the field generated by the signal in the wire will be changing direction along its length (positive then negative then positive and so on)thus cancelling any induced signals (could be crosstalk in a speach circuit) out

I am assuming that you have pushed the mini jack all the way in on the back of your P.C. I only ask because when I updated a bit of my audio equipment the plastic around the New jack was fatter and I had to shave some of it off before the jack would go all the way in.

Hmm.. Although it wont make any apparent difference to the activity of your computer, I wont recommend it for long run .. Squashed and cramped cables will torn up sooner than they are expected to .. And as Murphy's law states "If anything can go wrong, It will go wrong" those wires will attract cobwebs or all other things like that .. \nI'll suggest you to organize them .. :)

There could be a problem with the wiring since you say it corrected itself before.  It maybe time to get another set of speakers.

To explain this, I would have to use many words, so here's a website to sum it up for you:\nhttp://electronics.howstuffworks.com/speaker.htm

It may be the problem of your sound card or may be the wire of the speakers nothing else.

Check the D-sub cable loosened or not.\nLCD set up the wrong source state.

is it possible that you sound card or setting are set to mono rather than stereo. this would mean that the computer might only be sending signals to one speaker\n\nhope this helps

Stranded wires have slightly higher inductance than solid wires, but this is noticable only on transmission lines and larger conductors. if you are only using a short conductor, i don't think the inductance of the wire will affect the system, unless the wire is coiled.

Your wire is too thin...go for a heavier gauge wire and that will cure the problem.\n\nGood Luck

the distance information has to travel from one station to another before connecting, can slow down all browser abilities to a crawl.  Might check the cable and go to a higher grade.

Not a real problem if you don't dig too deep. Quiet often, back in the days when I repaired speakers, the connection from the voice coil to the speaker contact wires would break from vibration. Un-winding just enough of the wire (coil) to re-do the connection saved many an expensive speaker.

The router manufacturers will tell you they broadcast several hundred feet--but in reality (through walls and floors) don't expect more than 50 feet.  I had my best luck using a USB receiver on a pc (you can extend the usb connection about 20 feet before you lose signal through the cable.  (USB also lets you change computers quickly.)  If you extend your antenna wire (for your PCI card or on your router)--I was assured that you could add up to 100 feet of antenna cable (for a slight loss.)\n\nYou will find that experimentation with your particular system will yield your best results.

Maybe the connecter on one end is loose. It may seem silly to say, but loose connections on my T|X end always seem to happen! Try unplugging and replugging.

I found a rather technical but useful page about this.\n\nIt seems without fully reading the page that RS485 uses balanced lines, which means it has two wires for the signal rather than one, the second wire carries an inverted version of the data.\n\nThe reason behind this is that if the cable picks up current from neighbouring cables it will be the same on both wires and will be distinguished from the data because the data always shows up as an opposite signal on the second wire.\n\nThis makes for quite a robust line (in terms of magnetic, electrical and radio interference) which allows you to use the serial link over much longer distances.\n\nThere are other differences but I’ll let you read about them.
