Cisco 7937G - External Audio Input/Muting

When I connect an external audio source to the External Audio Input Connector (2.5mm stereo jack) are the internal microphones muted?
If this is not the case will the Mute Buttom mute the internal mics only or both the internal mics & external audio input?

Please refer to the blog below:

External Audio Input

Recently I discovered that my macbook does not recognize any external microphone plugged in through the audio input jack. If I do not change my preferences in Sound, then it continues to use the internal mic. If I change my preferences in the Sound pane to "audio line-in port", then no one can hear me when I speak into the plugged in mic. Is there a driver or something I'm missing? Help!

Welcome to the Discussions.....you will need an amplified microphone for a Mac or something like this....

Macbook Pro, audio input

I have a Macbook Pro 13". I would like to use the "Headphone" port as a "Microphopne" port and connect to an external audio input source (Mixer in a DJ set-up) and record my mixes. I have followed the instructions listed on various forums to do this but my computer does not give me the option to change from Sound Output to Sound Input under the tab "use audio port for" which can be found under System Preferences/Sound in the Apple drop down menu. I believe Apple for whatever reason dropped the external mic function on their newer Macbook Pro laptops. What can I do to fix this ?

Perhaps this is what you are looking for...

Trying to hear external audio equipment through iMac in real time

I am trying to use my iMac G5 to listen to an external audio input source (technics 1200 turntable via a vestax mixer). I have the unit plugged in through an rca to 3.5mm minijack to the audio-in port.
In system preferences for INPUT I have selected "Audio line-in port". The Settings for selected device are as follows:
Input Volume: max
Output volume: 3/4 max
Mute: not selected
When the turntable is playing the Input Level meter in the Sound>Input window registers it just fine, but no sound is coming out through my computer's speakers (for "Output" I have selected "Internal Speakers Built-in Audio", with the balance in the middle, and the Output Volume at 3/4 max).
Further, using sound studio I can record the turntable and play it back, but I still cannot hear it while it is recording in realtime!
Is there anyway to listen to an external device in realtime through my iMac??
Thanks in advance for your suggestions,
Chris

Christopher-
Greetings!
While this may not answer your specific problem, maybe it will help.
I have noticed that from time to time I will be running an application, and for example I select internal speakers, and they work just fine.
Then I will quit that application and go into another, and suddenly the sound is coming out of the external speakers! I look in the sound-preferences and "internal speakers" are clearly selected.
To correct this, I just select external speakers, then reselect internal and it works just fine. Since it is a fairly simple work-around, I haven't bothered to research it any further and just accepted it as "one of those things".
Perhaps you have already tried doing this, but if not, maybe give that a shot (select external then reselect internal) and see what happens. If that doesn't do it, then perhaps someone else will happen a long with an answer for you.
Good Luck!

External mic inputs and speaker outputs for CP-7937G Conf Phone

Has any tried to connect the Polycom® SoundStation IP Multi-Interface to the Cisco Conference Station CP-7937G Phone, it appears to be the only way to get eextra mic inputs and line level outputs for enhancing conference call? See attached Quick Start Guide.

Here's where I am on interfacing external mikes, PCs, speakers, etc. with the Cisco 7937. It seems this I/O port is quite a mystery to both Cisco and the manufacturer (Polycom). There are virtually no technical specs for it anywhere on line. So, I bought a variety of cables and connectors and tried exploring. I could never get anything but input into the 7937 to work. I could never get any output from it despite the output symbol next to the port. Here are the input test results:
3 pole 2.5mm to dual stereo 3.5mm breakout cable didn't work at all
4 pole 2.5mm to stereo 3.5mm for input worked only on one pole (red connection). Half volume?
3 pole 2.5mm to stereo 3.5mm for input works only on white connector (louder?)
3 pole 2.5mm to mono 3.5mm for input, works (louder?)
2 pole 2.5mm to stereo 3.5mm for input, works
2 pole 2.5mm to mono 3.5mm for input ,works, and is simplest.
So, if you want to feed an external audio source into the Cisco 7937, almost any type of 2.5mm male connector cable at the 7937 will work
I could never find any mention of successful use online, and could not find an output signal myself, so I suspect the 7937 was just mislabeled.

How do I synchronise my Intel iMac's SPDIF audio input to an external clock source?

How do I synchronise my Intel iMac's SPDIF audio input to an external clock source?
I have a Focusrite ISA One microphone pre-amp with digital ADC card fitted. Both devices are set to 24 bit/44.1kHz and connected by Optical cable (from ISA One to iMac's optical SPDIF input)
I've tried to get the iMac to slave to the ISA One's digital clock by looking in the Audio MIDI set-up but cannot get it out of 'Default' mode. Focusrite tell me it needs to be 'Locked' in the Mac but I can't see how to do that.
The Mac recognises when I change the ISA One's sample rate because Pro Tools gives me an alert, which would suggest that it's receiving data. But all I am hearing on the input is digital white noise.
Any ideas?
Cheers!

USB and FireWire work in very different ways, so there is no adapter.
Instead, you should just get a USB 2.0 hub, like this one
http://eshop.macsales.com/item/NewerTech/USB2HB7PRO/
There are many choices, but be sure to get one that is powered (it comes with its own power supply). Cheaper hubs rely on the computer's USB port for power.

As there is no audio input on the new iMac range, What external equipment will allow me to record onto my iMac ?

As there is no audio input port on the new imac range, what external epuipment can i use to record dj podcasts from a pioneer DJM 700 mixer?

I'd be inclined to use something like the Numark Stereo I/O. If you're currently using the line-in on an iMac then you will see a drastic improvement.

That said, you can spend as much or as little as your wallet will allow on a USB input device, more investment brings better quality ADCs, higher bit rates, lower latency and more inputs.

Audio input through external microphone not 'heard' by computer

I can record audio with any app through the builtin mic. And I know the system 'hears' sound through the builtin mic when I go to SystemPreferences->Sound->Input.
I have an external microphone that I want to record through. I went to SystemPreferences->Sound->Input and chose 'Line In' and plugged in the microphone's lead into the 'in' jack. However the SystemPreferences->Sound->Input Input Level sensor/detector is dead -- it shows no audio input. Nor does iMovie pick up any audio input when the mic is plugged in.
I know the input jack works by plugging in the output pin from a cassette-player, choosing 'Line In', and playing a cassette. The Input Level sensor/detector comes on and the sound is available to apps.
I know the external microphone works by plugging it into the cassette-player and recording from it and tapping and rubbing on its pick-up. The sounds are captured on cassette tape.
So why is audio input through external microphone not 'heard' by the computer? Is there some trick to making it work?

There are a few possibilities, but the most likely is that your microphone does not produce enough signal to be "heard" through the Mac line input. Usually this is normal, with most microphones producing perhaps 1/100th of the signal needed, which would be called "mic level".
You cassette deck probably outputs "line level", much stronger and strong enough to register in the Mac Line input. Similarly, the cassette deck microphone input is probably "mic level" and much more sensitive than the Mac line input.
There are other possibilities, such as a powered microphone, but you have not provided any model numbers or specifications to analyze.
Try this: plug in the microphone like you did before, and make a really loud sound right in front of the mike, like clapping hands. You may see or hear a faint sound register on the Mac.
The usual cure is to buy a microphone preamplifer. You can also buy a new microphone with a built-in preamplifier. You can also buy a USB microphone or preamplifier device that bypasses the analog Line input entirely.

External stereo device to Powerbook G4 audio input

Hi
I am trying to convert all my old cassettes into MP3's. I was trying to use Audacity which supposedly can grab the audio from the audio input and record it in MP3 format. It seems that my Powerbook G4 recongnizes the built-in mic, cd device, and the USB/firewire ports as valid audio input devices. How can I connect my cassette recorder to my Powerbook? I tried to connect it to the minijack port (the one with two triangles and a circle inside) but the input was not reconginzed. Can anyone suggest anything please?
Also, (may be a bit out of topic) would iTunes be able to do the recording?
Regards
Arijit

I have been unable to get the microphone input with a Viewsonic 22" monitor with webcam to work with either iChat or iVisit with my Mac Pro. There have been other reports on the web about newer versions of the OS 10 inactivating the audio input for several programs. Is this why the microphone does not work or is it true that the audio input does not act as one? If the audio input does not work with an external microphone, what is it for?

External microphones don't work with audio input

Tell me its not true that an ordinary mic won't work with the audio input....I have 2 mics which I know to work mini jack [tried both stereo and mono] and zip! nothing....what is wrong with this equation
any ideas from the floor? [do I really have to go and buy another usb headset or an iMic to resolve this??
please tell me there's another option!
thanks
Tony

Why doesn't my audio input work?

I have a Macbook with OS X and have never been able to get an external microphone to produce sound on the computer. I was using an old pair of headphones but the brand new pair I bought also do not produce any sound. They are the basic headphones with a mic attached and plug into the Macbook using two mini-plugs in the two audio ports (one for input, one for output). I can hear sounds in the headphones just fine. But I'm only able to talk if I use the internal microphone on the Macbook, which is inconvenient as it picks up too much background noise. I'd rather use the external mic.
When I got into my preferences > sound > input, there are two choices there:
Internal microphone -- type: Built-In
Line In -- type: Audio Line-in Port
I select the second option and nothing works. Am I missing something here?

Well, FWIW, I did a lot of searching on here and it seems that this type of basic, unpowered mic will not work with my Macbook Pro (OS 10.7.5) and that any audio input has to be powered in some way -- a cd player for example that provides a powered signal into a pair of headphones or into the computer. I bought one of those very basic $15 headsets with microphone from Wal-Mart. Two different brands failed to produce any sound. (though the sound OUTPUT to the headphones works just fine)
Oddly enough, I did call Apple Tech Support and they were confused and unaware of why the headset' mic shouldn't work just fine. So apparently, this is not a "known" issue. So I'm just going to pay a little more and go buy a Bluetooth or USB headset.

Bootcamp 3.1 & Windows 7 x64 - no external sound input, low speakers level

Hi all,
I just installed long awaited Bootcamp 3.1 update. I am rather disappointed.
The only thing that has changed is that the red light on the audio output is off. This thing actually bothered me the least.
External sound input line does not seem to work at all. No matter if mike or standard line device is connected. System recognizes that something is connected but there is no sound coming, level indicator does not rise.
Speakers level is still low. As far as I know all it takes to fix it is to alter some settings in the *.ini file. Someone did it and posted for other to download but why it is sho hard for Cirrus and Apple? What is the matter?
Is there any way to get sound output via Mini Port under Windows 7?
System does not even see such device.
Thanks,
Thomas

What about the iMac though? 2008 Model w/ Realtek to be specific. The audio is low and poor and I haven't even tried the audio out. I'm running Win7 x64 and everything works well aside from my audio and my external WD Studio FW800 drive disconnecting randomly with repeated directory changes. I can avoid that on my system... but the audio is a real disappointment. Makes me feel like I need an external FW sound card.

Captivate 4 not detecting audio input from USB Microphone

I'm using a Logitech USB microphone in Captivate 4. When I try to calibrate it, Captivate 4 is not detecting any sound. It is set up properly. In the "audio settings" menu, this microphone is listed in the drop down list. I have selected it as the input device. However, when I try to "calibrate" this microphone, no audio is detectable. Captivate 4 is detecting the device, but not the audio input. I have double checked all the usual suspects--this microphone is selected as the default recording device. It does not use special software or drivers. It is designed to use the drivers in Vista. It works fine with other applications. I have made sure the input level is detectable. I've checked to make sure it is not muted. I have other microphones (non-USB cheapies) that work fine, but I can't get this specific USB microphone to work.
Suggestions?

Digital audio input via mini jack/toslink from ADA, monitored via USB audio output... is this do-able? I know digital audio input should be okay but how do I monitor it, apart from using the internal speakers?

Digital audio input via mini jack/toslink from ADA converter, monitored via USB audio output to amplifier... is this do-able? I know digital audio input should be okay but how do I monitor it, apart from using the internal speakers?

You can output audio thru HDMI, with appropriate adapter.
You can use additional cheap external usb audio for monitoring.

Can I use HDMI port on my Macbook Pro for digital audio INPUT?

Trying to find a way to get digital audio input to my new MBP with retina. HDMI supports audio and video, so can I use that port as an input?

It is not recommenced to use TimeMachine in a partition, either on the boot drive or externals because of problems in the past with that arrangement.
You also need hardware protection in addition to software protection.
If you want to do what I do, which is have a second 50% partition bootable clone of the first.
1: Use BootCamp software to create yourself a 50% sized partition, then exit the program. (you also can do it in Disk Utility, but it's tricky)
2: Head to Disk Utility and select the BOOTCAMP partition and change it's name and format to OS X Extended Journaled.
(To map off bad sectors in advance, use Disk Utility Erase with the next to last on the right selection, improves reliability and makes for faster reads)
3: Download Carbon Copy Cloner, now select your Macintosh HD partition and clone it to the second partition.
4: Whenever you want to boot from the second partition, just hold the option key down on the keyboard to select it to boot from.
You can access the folders on the second boot partition as well, to grab deleted files you accidentally erased (which is a rare thing for most to occur) however you should leave it alone and as a clone.
You can update the clone when you need to, or schedule it to run automatically.
You should also do this occasionally with a external drive, as the internal drive can die and take both partitions with it.
I currently do this with my laptop, that way if I'm mobile and have a serious issue, I can boot from the cloned partition in seconds without carrying a drive around. If I need large space for something I wasn't aware of, I can erase the clone partition and later clone it again.
Software does all the work, just pick a time your not using the machine and let it work. Painless really.
