Hello. An electrician I am not. I have a problem and don't know who
to take it to. I was capturing video from a SVHS player/recorder
into a Matrox RT2000 break out box. Instead of having the audio
cables on the audio out jacks of SVHS, I had them on the input jacks.
Now I can't hear or capture audio. What happened?

I thought I'd test the devices. I hooked my vcr back to the tv; it
works fine. I hooked up the dvd player to the computer. No audio.
Next, I took audio in jacks out of the Matrox and connected them to
my sound card. Audio. But very loud and I could'nt contol it with
volume settings. As I was clicking through the settings the audio
vanished. I still get audio from the system, but can't feed it into
the system from an external source.

Can someone explain this to me? I know I once wanted to hook up
speakers to my laptop and put them into the mic jack instead of the
output jack and the mic in the laptop has'nt worked since. Any help
on how I can fix all this would be greatly appreciated.

Thanks.

jw,

Well, actually we electronics types sometimes jokingly call electricians,
Glorifies Plumbers, they love it. :-)

I was capturing video from a SVHS player/recorder
into a Matrox RT2000 break out box. Instead of having the audio
cables on the audio out jacks of SVHS, I had them on the input jacks.

OK, are you saying that you successful captured the audio and now it
doesn't work? Or that it never worked. Nothing you described give
me enough information to help you.

I thought I'd test the devices. I hooked my vcr back to the tv; it
works fine.

So the VCR.

I hooked up the dvd player to the computer. No audio.

Whoops, now we've changed gears, that's like an equation with
more than one unknown. So far we've verified that the VCR
audio is probably OK. But we don't necessarily know about the
DVD player or the computer line in. Am I correct in assuming
that your VCR test involved only the RF connection, i.e. to the
TV antenna input? If so the VCR audio output could still be
bad though this is unlikely. With the VCR working into the
TV set, try to set up the VCR so that instead of using it's tuner
it responds to the video audio input jacks. Then connect the DVD
to those jacks. That will confirm that the DVD machine is OK.
(I'm also assuming that the DVD is a separate player, not on
the computer.

Next, I took audio in jacks out of the Matrox and connected them to
my sound card. Audio. But very loud and I could'nt contol it with
volume settings. As I was clicking through the settings the audio
vanished. I still get audio from the system, but can't feed it into
the system from an external source.

You know the old computer voice response, "Not enough information
to compute."? Need more detail in each step, what do you mean 'clicking
through the settings, on the computer? Where? Audio from the system,
The computer?

Can someone explain this to me?

Not until you explain what you are doing more specifically.

I know I once wanted to hook up
speakers to my laptop and put them into the mic jack instead of the
output jack and the mic in the laptop has'nt worked since. Any help

Let's stick with one problem at a time.

Hmmmm. Somehow the problem solved itself. So, it must've been in the
software somehow. I thought I blew a hardware connection. But,
maybe you can explain the mic in the computer and what happens when
you mistake your output jacks for input jacks...

I was wanting to play sound out of my laptop through a couple of
speakers. But, I connected the speakers into the mic jack instead of
the sound out jack. My mic has'nt worked since. ?
