Audio problems range from extraneous noses (buzz, whine, etc) to no sound at
all.
Noise:
For those problems that you have extraneous nose the problem is in the cable,
the connection at the sound out port, or the connection on the speaker.
It could well be a cable has what is called a
cold solder jointwhere part of
the cable is not completely soldered to the connection.
Because these cables are very thin there are only a few strands of wire in
them, excessive bending can break the wires, this could also cause the lack of
or extraneous sound.
To find a bad connection gently move the cable back and forth at all
connections, on the speaker and at the computer connection, does the sound stop
and start?
