What steps will reproduce the problem?
1. Soundflowerbed -> Audio Setup
2. Select a DisplayPort output and click on "Configure Speakers..."
3. Click on "left front" or "right front"

What is the expected output? What do you see instead?
The speaker is supposed to "play a sound."
A very jarring loud noise comes out of the speaker.

I’m getting the same very loud noise. It sounds like feedback and you can’t 
lower the volume.

Everything was working fine so I know it can work
Then I opened Audio Midi Setup and moved the format to see what would happen 
and then that loud noise took over. Moving the format again does not make that 
terrible noise stop.

I am running OS 10.8.5 and Soundflower 1.6.6b

I have tried several times to get Soundflower to work again but to no avail. 
The only way to stop the noise is to selected internal speakers in System 
Preferences but then I can’t get sound on with the screen recording feature 
in QuickTime.

Any ideas of how to resolve this?

I experimented with the situation a bit more today. When I click on “Built in 
Output” it always stays checked and the low frequency feedback begins. If I 
open Audio Midi Settings and adjust the frequency in Soundflower’s 2nd 
channel the tone changes slightly. 44100.0 Hz is a lower loud blasting sound 
and 96000.00 Hz is a higher loud blasting sound.

It all started when I wanted to record a short video on my computer via 
QuickTime with sound so I downloaded Soundflower. Soundflower worked as far as 
allowing me to record sound with QuickTime (a feature Apple should have just 
included with the software).

I noticed the volume was always very low after installing Soundflower and I 
didn’t like it. At times when I was just watching a video I could hardly hear 
it. I began looking for a way to increase the volume. 

I found Audio Midi Setup and was able to adjust the volume and that worked 
great. I remember thinking, “I wonder what this does?” …and the rest is 
history as I touched the frequency pulldown menu. Why did I ever touch that?! 
That’s when the loud blasting feedback like sound began. Imagine your 
computer’s speakers on full blast… it’s sounds that loud.

If I click on Soundflower’s Built in Output the loud sound begins. The same 
happens when I click on the frequency pulldown menu in Audio Midi Setup. If I 
quit Audio Midi Setup the sound continues. It’s only when I quit Soundflower 
doses the blast finally stop.

Also, I cannot get Soundflower to work at all anymore. If I try to bus the 
sound through Soundflower it is dead silent… until I adjust something to 
start that feedback again. 

Did I meant ion it is very loud yet? It is not possible to adjust the volume 
through any of the following means: (in fact I haven’t found anything to be 
able to turn it down)

Keyboard volume controls including “off”, System Preferences, Audio Midi 
Setup volume controls, Audio Midi Setup preferences.

I used the uninstall script provided and then reinstalled Soundflower but 
nothing changed. It won’t work at all since this feedback noise began. There 
must be an extension or some part of a file not erased.

Setting System Preferences output as default sets everything back to normal. 
However, I can’t record audio with Apple’s deficient QuickTime screen 
recording (what’s the point of recording without audio? I asked knowingly).

I’m running OS X.8.4 (I accidentally typed 5 above… stupid crappy, dinky 
little keyboard. How can anyone fit their hands on this puny little piece of 
crap keyboard?!).

Has anyone come to a conclusion to this? 
Because I have the exact same problem as you guys and i cant think of anything 
that might fix it..

That means your headphones are looping the sound through your mic
Basically this is happening

Mic ----> headphones  ---- > mic   -----> headphones
Making everything you hear in your headphones repeat through your mic, repeat 
through your headphones, looping your headphones over your mic, making it 
duplicate sound over and over again. 
It happened to me, but I never found out how to fix it, I uninstalled 
soundflower, tried again and it worked, don't know what I broke, but an 
uninstallation and reinstallation fixed it.
