Jack plugged in but there is no jack

Windows (and Linux too) shows me that a jack is being plugged in and out constantly. Is it a hardware malfunction? Shoul I have my board replaced?

Headphone port does not work on acer aspire 5250

Click Start, Go to control panel, then Hardware and Sound, then Sound. Click "manage audio devices". Plug in your headphones and see if they show up.

If they don't, your divers are missing or the the headphone jack is broken or clogged. The most common reason they don't show up is actually gunk in the jack, so make sure it's clean with a bright flashlight and use a toothpick or something similar to clean it out.

If they don't show up and your jack is clean, use windows update (it will detect many of your missing drivers) or go to, click on support, drivers, and enter your model number and download the audio driver and install it.

If you DO see the headphones show up as an audio device. Then just set them as default (by clicking "set as default") and it will work.

Hope this helps!

What do i need to program a speakercraft mzc64, mzc66, mzc88 ?

This info is meant for all the Speakercraft MZC controllers.

The software used to program the mzc controllers is called EZ TOOLS the latest version of which is 401. This version handles both the IR database versions released in these units.

V313 is the older one and 401 is the latter.

you will need a laptop which runs windows, EZ tools is native to XP but should work emulated under later versions of windows. I have this running on linux under wine with some basic command line mods to allow the com port to be seen by wine, this works well although some of the rendering of graphics looks incorrect but still good enough to use.

You also need a cable with a female 9 pin d sub at one end and a stereo 3.5mm jack plug at the other, use screened cable.

The correct port to use on the back of the mzc is the jack com port not the dsub rs232 port.

There is no way to copy theprogram off a machine, you have to either have the origion project file that works in ez tools or start from scratch with a new file.

If you need to transfer from one mzc to another one if the first mzc unit has failed hardware, you can remove the rom chip which is plugged into the control board located behind the front panel. This can be swapped over to the other mzc and is the identity of the mzc controller.

For making up a communication cable use the following pins..

Pin2 dsub to tip of jack
Pin3 dsub to ring of jack
Pin5 dsub to earth jack

Trust this info helps.

Dell 546 desk top. No audio from external speakers. Downloaded driver. No help. Any ideas?

If you are using Windows, try going in the the Device or Hardware manager and removing the device. Then, look on the menu bar at the top to rescan for hardware changes. Sometimes this is the best option. I am assuming that the speakers work, but, I would plug in a set of headphones to be sure. Also, sounds dumb, but ensure that you are not plugging the speakers into the mic jack (microphone) or the line-out jack (low level output) instead of the headphone jack.

Can i connect ethernet cable to my 6 years old packard bell desktop

As your Laptop itself doesn't have a ethernet card, you can't connect it. But I have a solution, you can buy a USB Ethernet Adapter, which you can buy for a cheap price and you won't need to open up your laptop or any stuff like that. Just plug into your USB port and start working with Ethernet.

It looks like this:


Hope this helps.

Headphone jack does not work, audio still plays from speakers

sound like the hardware supporting your headphones may have disconnected from its solder.This could have happened from dropping the notebook with the headphones plugged in and landing badly, or a strong or constant tug on the input. Otherwise, it could be a software configuration like you've tried

No response to my microphone

1st try to check if the driver of your sound card is properly  installed in your operating system, if youre using windows it will be on the device manager 2nd if it is installed or its not showing then 90% would be a hardware problem on your sound card or the jack itself
