Audio input clicks when input connected
when i plug in any input source into the audio input on my macbook. all it does is click.
did i fry something?
Did you look at System Preferences, Sound, Input, and check the input volume level?

Audio pops/clicks when changing angles in multicam clips
I am having problems with audio pops/clicks when working with angle switching in multicam clips. it always occurs when i utilize any of the "audio enhancements" features, such as the loudness or background noise removal features. Switching angles results in audible audio pops. The only way to get rid of them is to disable the audio enhancements. This occurs regardless of the audio source. Is this a known bug that is being addressed? I rely heavily on the audio editing features in my work and am hoping this will be resolved in an update soon. Thanks for any help-
Hi Brad, thanks for the reply!
That sounds like a good workaround. What I have been doing in the meantime is create a new compound clip after I finish all of my cuts, and then apply the audio edits to the new contiguous audio clip in the compound clip.
What is really strange and frustrating is that all of my new audio bugginess really began when I could no longer detach audio from my multicam clips in 10.0.9... After doing many searches here, it seems that in this most recent update of FCPX this is no longer a 'feature'... I don't know why they changed this, but in older updates of FCPX you could detach audio from original clips, compound clips, or multicam clips with no problems. I would routinely create and edit all of the angle cuts in my multicam clips in the timeline, and then if I wanted to, be able to detach the audio and do more edits if needed. Thankfully I can still apply edits to compound audio clips, but it would sure be nice if I could just correct/enhance audio without ugly-sounding artifacts in multicam edits. Thanks again- -
Audio pops/clicks when using external speakers
Here's the problem -- When my Mac plays a sound and it had not played any sounds for a while, it always pops (or clicks, same thing, just a matter of magnitude). There is no pop if there was sound recently, like in the last 3 minutes or so.
My iMac is an aluminum 20" model purchased in May 2008. I have external speakers playing audio. I don't think the pop happens when it's just the internal speakers.
Is there an audio driver update? The Software Update menu doesn't find anything newer to install for me. The pop is very irritating and I consider this Mac to be broken with respect to audio output.Finally, a workaround. From another thread I learned that this is an old issue. The Mac shuts off the audio output electronics after some period of inactivity. When it reactivates, an audible pop happens. It's an old issue that Apple for some stupid reason doesn't care to solve. For a company that espouses fluid, integrated user experience, it is incredible that Apple could allow such a glaring audio defect to persist through so many generations of products. Surely they must realize many users will be connecting external amplified speaker systems to the analog audio out port. Doesn't anyone at Apple test the computers against the variety of input loads the audio output circuitry will be interfaced to? I understand that Apple has no control over the variety input impedances and DC biases their audio output electronics will see. But I think the popping could be avoided if they just employed a simpler scheme where the audio electronics do shut off. They are too smart for their own good.
That said, the hack that is so far working for me is this freeware utility KeepSoundAwake that plays an inaudible sound periodically. I would much rather see a solution in the firmware. -
Audio fade-in when headset connected
When I have my headset connected and play a song, it fades in whenever I play a song. That is very annoying, how do I turn that off? Also, why did RIM put that annoying feature there in the first place? I have the curve 8530 with OS version 5.
If this is the case Then there must be some switch somewhere in the bowels of the project data that can be thrown. Once again i am appalled at how little information is available to power users and apple should be ashamed of it self. THese damned programs do not work as advertised when pushed and they display anomalies that keep the forums full but nothing else. I had this problem and had to export the whole movie as is and then reimport it in order to over come the INVERSE DUCKING feature so prominently in fashion these days. I will be trying now to see how this works ... again.
PS none of my issues with inverse ducking matched what you did to solve yours -- My project had been completed and now someone wanted tweaks so when i went in to make the tweaks- that is what i found . Sort of like magical apperance of unnamed temporary files amongst other things. -

My Blu-Ray player has a USB input but it doesn't have an HDMI input. Can I connect my Apple TV to the Blu-Ray using an HDMI/ USB adapter? It would allow me to run the audio through my stereo. Thanks to all for your help.
Can I connect my Apple TV to the Blu-Ray using an HDMI/ USB adapter?
If you can find such a thing. I really doubt that exists since USB is a data connector not a video connector.
would allow me to run the audio through my stereo.
That would depend on this adapter. -

The number pad would not let me type in a 1 2 3 for my 4 digit code. After numerous tries, the phone now says iphone disabled connect to itunes. When I connected to itunes, it asked for the code which I was unable to enter. Help!
Open iTunes on computer, connect iPhone to computer with USB cable. Hold both Home and Power buttons on iPhone until iTunes recognizes iPhone in Recovery Mode. This usually takes about 20 seconds of holding both buttons. Restore the iPhone Firmware.

I am using iMac OS 10.7.2 with Garageband'11 6.0.4. I can't record sound from mixer Behringer X1622USB using USB out. when I connect the mixer to iMac via USB appears USB Audio CODEC on Sound and Preferences but I can't get no sound from mixer to iMac only sound from iMac to mixer. I only can record sound using microphone line in. Please help.
Eric,
Thanks for your reply. Realtek audio works only in playback. There is a stereo mix in the mixer but the recording controls are not operable with no sliders in the mixer for any recording option. Slider controls appear to be grayed out. Can't figure out how to enable them. Downloaded newest drivers to no avail.
The M Audio control panel has no apparent option for recording stereo mix. Adobe ignores the sound from the DVD or CD and shows flatline.
I'm trying to record the sound from the DVD not rip the track.
When I go to Audio Driver Setup and select Audition 3.0 windows sound, there is no input device installed.
I'm thinking of going back to a decent internal Soundblaster card like I have on my 8 year old machine I am replacing. -
Audio clicks when playback is stopped.
In the process of recording a couple of bass guitars that were Keymapped into sampler instruments, I noticed some strange audio behavior. While playing the new sampler instruments, finger lift off from my MIDI guitar controller was causing a clicking or sucking sound each and every time. (The recorded notes in Logic were allowed to decay naturally and the samples were not looped.)
So I went to the recording in Logic and sure enough, hitting the space bar or numerical decimal would elicit a click when stopping playback. A quick test recording was completed in Digital Performer with the same result. Also a quick test in Logic with the smallest and largest i/O settings. Same problem.
Recording signal into the Mac via Built-in Line input also produces the same clicking. So that removes suspicion for my interface (828mkll with Black Lion mod) which has been a rock-solid performer.
I have 5 GB of Ram. OSX10.5.5, 7200 RPM sata drives, etc.
Is this some sort of core audio issue?
What to do???Ok, I recorded each bass chromatically into Logic in real time (not triggering samples via MIDI).
The resulting audio files were opened in Keymap to be converted to an EXS24 sampler instruments.
The lift off clicking noise occurs with both basses but not with factory sampler instruments I play with the Godin LGX-SA.
The point about the spacebar or numerical pad decimal point is that when I use either of these to stop/start playback of the original audio file in Logic, clicking occurs. Uninterrupted audio playback is fine. Interrupted playback causes clicking which should not occur. While attempting to problem solve the funny lift off noise while playing the sampler instruments, I noticed that interrupting playback of the original recording in Logic caused clicking.
I recorded the same bass guitars into DP (not MIDI-triggered samples) through the same interface with the same clicking problem when audio file playback is stopped via the spacebar or DP keyboard commands.
So there are no MIDI messages involved here. The point of mentioning the sampler instruments is just that that was the when I noticed the audio problem. For simplicity sake, if we leave sampler instruments out of the discussion, I am still left with some sort of audio problem.
The same basses played and recorded via Built-in Line input causes the same clicking to occur during interrupted played back.
Somehow. the noise that occurs with finger release from the fretboard is related to the problem with the audio clicking when stopped during playback. Meaning that the audio file is corrupt in some way.
I followed your suggestion of unchecking both play tickboxes in the Sound Effects tab of the Sound preference. The problem still exits.
So in summary, at this time, I cannot record audio into my Mac without some sort of clicking problem when stopping playback. Audio that I record then causes some strange lift off noise or click when played as a sampler instrument. The base problem is that something goes wrong when audio is recorded into my Mac. -
IPod nano's audio fried when USB connecter touched car charge power
In my car, I have a splitter for the "cigarette lighter" power, with two holes facing up. There is no aux jack on the car's radio, so I also have a little radio transmitter, and it gets power from that splitter. An audio cable connects the output of my iPod nano to the audio input of the radio transmitter. My nano had a 30-pin cable connected to it, too.
One of the "cigarette ligher" power splitter's power locations was empty, just a hole facing up. The power splitter also has a couple of USB ports, and I was in the process of attaching my nano with the 30-pin cable into that USB port for power. Unfortunately, the USB connector touched inside the power hole.
So the nano got some voltage from the car battery and/or grounded things in a weird way through the audio of the radio transmitter (connected to the car's power) and the USB end of the 30-pin cable touching the car's power.
The nano's screen froze, and it didn't respond to any button presses. So I figured it was totally fried, but it's not. Once the battery ran down, I could connect it to my Mac, and now everything but the audio is working okay. Through the 30-pin USB connection, I can load up songs from the Mac and play music out of a clock radio.
The probablem I'm writing about is that the sound coming out of the headphones is either non-existant or extremely garbled, depending on the volume level. It's fried. Can anybody give me some hope for un-frying the audio?OK, so here is my problem. I did originally download the Beta 10.10... Apparently I kept on getting betas and was running 10.10.2 (which today is still in beta).
I did downgrade to 10.10.1 (by clicking "Download" in the App Store).
Right after the downgrade everything with syncing works perfectly.
Cheers, hope this helps someone. -

Apple TV optical Audio stops working when connected to switch
Hi everyone,
I'm installing a brand new Apple TV in the following setup:
Apple TV (is up to date)
- HDMI to HD Beamer
- Optical Audio to Sonos Playbar (Works instantly)
- Optical audio through switch to Sonos Playbar which doesn't work
UPC Box
- HDMI to HD Beamer
- Optical audio to switch to Sonos Playbar (Works instantly)
I've tested all the ports on the switch and cables already and they all work. So the weird thing is when I connect the optical from Sonos directly to the Apple TV it works perfect. But when I use the switch it doesn't work. I see a light in the switch so there should be signal...
The switch I'm using is:
