How can I use two microphones ??

[king21]

How can I use two microphones ?? please help

hye everyone

I use High Definition Audio Controller


the problem is this:

In windows xp

I used 2 microphones (in skype for example), one in rear (back) jack and the other in font jack so

but

In windows 7

I can use only one microphone. If I connect two microphones, automatically one of them becomes the default one so I can use only this one the default

sorry about my English

thanks anyway

Use an external mixer, connect the two mic's to the mixer and then connect the mixer output to the PC's mic jack.

well, it isn't working but thanks for this suggestion

any other idea ??

What doesn't work? If you have a mixer that has more than one input you should be able to use both inputs (e.g. mics) at the same time and have both on the output. That is how a standard P.A. system works. The PC doesn't distinguish between the mics all it knows is that it has an input on the mic input and whatever the input is, it uses. If you had a mixer with 10 mic inputs and you used all 10 at the same time it would work the same way.

If you are trying to use two mics into two different applications at the same time then it won't work.

the mixer that I have working with output only

If you are trying to use two mics into two different applications at the same time then it won't work.

well, I tried to use two mics into two jacks at the same time in windows XP and the two of them worked fine in on software (example: Skype)

XP did not have jack sensing support even for those systems where the hardware provided it - which is why your system used to work

it may be possible in win7 to get the same thing but would depend on the actual hardware and the driver options - on a built in sound chip you may have a way to disable jack switching in the BIOS, this may also be available in the driver.


Other more drastic methods is to physically disconnect the jack sensor wire inside the case

or

ad a PCI or USB secondary sound card

I tried to disable jack switching in the BIOS but I can't find any option for jack switching. I'll try to disconnect the jack sensor wire inside the case

Have you gone into Audio Devices and changed your inputs to Listen?

 

[king21]

I tried, nothing working always makes me choose the default and that's it. the mixer doesn't work with input like I said before. I can't believe that the problem in w7 but not in XP !!!!

well, maybe I'll use Virtual-Box software to use windows xp for communications like yahoo messenger and skype

thanks BugOutMachine for everything and welcome with other suggestions

Did you try picking a different device in the applications themselves? I know Skype can use a different input device then the default. However if your hardware treats the two inputs as one you cannot.

 

[Barman58]

The whole reason for using jack sensing is due I think to the popularity of laptops where "private listening" is often required.

Pop the headset into the jack and the speakers and in-built mic are switched off

It's also useful for desktops where under the old system you would have to scrabble around at the back of the tower to switch from speakers to headphones.

With the availability of reasonably priced USB or PCI sound cards for those specialist reasons when multiple input and/or output are required I think the current situation is the best.

Another complication with today's audio is the dual use that jack sockets are used for with surround sound where the front Mic and Headphone jacks may be used for front and or centre speaker supply. This has complicated the software drivers

I tried to do this

but this is the point, I want to use both of microphones

thanks for this information. Is this mean that I can't use two mics (multiple inputs) ??

note: I can use multiple outputs (Headphone & Speakers)

 

[Barman58]

What you are able to use at the same time will depend on what options are in your BIOS and Audio Drivers. It would appear that you are able to switch off the jack sensing for the speakers (as you state you can use headphones & speakers together). It may be that this option is not available on your system, (the dual use of output devices is a lot more popular than inputs), or you may not have set the option.

One place to check is in the audio driver for the sound chip, you should see an option to allow exclusive use for audio devices, un-checking this may or may not, give an improvement

What do you see in the jack display in the manufacturer's control panel, with the two mics inserted, it may allow you to re-assign .

Last resort for your needs would be a jack splitter cable which would allow you to connect both microphones to the same jack socket, more advanced would be a small mixer panel which would enable you to balance the two inputs to your needs, and then feed the combined signal to the PC.

The most professional option (quality Wise), would probably be the use, as I suggested, of a USB sound card which would allow you to totally control the inputs. They are available on-line for a few dollars/Ponds
