Distorted sound and echo on airplay extended display

Since the update to Mavericks, extending the display or mirroring to my 2nd gen AppleTV, causes distorted sound and echo. Any video or music has distortion and echo. This wasn't happening with mirroring prior to the update. Anyone else having a simliar issue?

go to your appleTV and choose the auto sound setting, not the 16bit sound setting

I need to connect my Imac 27'' (newest version) up to 3/4 monitors (all 40'' LCD tv's with VGA and HDMI connections) with extended display to all external screens, not duplicate images. Is this possible?

I would suggest you visit an Apple dealer, preferably an Apple Store if there's one in your city, and ask for assistance in determining what you need. The questions and issues you bring up are rather complex to address in a technical support forum and would be better addressed in person where you and the salesperson can ask questions back and forth to arrive at the optimal setup.

AirPlay Extended Display No Sound From TV

When I extend my desktop from my MacBook Pro 15" mid-2012 model to my tv connected via Apple TV, I can move windows to and from either screen no problem, but I cannot get sound to play through the speakers on my tv for some reason. I've tried going into system preferences and manually changing the sound output device from the computer's speakers to the Apple TV, but it will not allow me to select the Apple TV. I'm sure I'm not the only one who has had this issue. Has anyone ben able to resolve this?

I have the same problem. Found this solution to another problem. Might help in order to be able to select AppleTV for Audio using Alt+Volume menu.

It's a bug that seems to pop up occasionally after waking the computer from Sleep. Either reboot or open a terminal windows and paste:
sudo kill `ps -ax | grep 'coreaudiod' | grep 'sbin' |awk '{print $1}'`
Re: Can't select airport express

PulseAudio stops sounding when I switch to other display (Ctrl+Alt+F1)

Hello.
When I am playing any sound and I switch to a display (Ctrl+Alt+F1, Ctrl+Alt+F2...) where I have not loged in or a am not loged with my default user account, the sound stops, and when I switch back, I continues sounding.
Anyone have an idea of what could be causing this?
Thanks.

Thanks for the reply.
Is there a way to change that behavior?
Edit: After killing console-kit-daemon, sound works on all displays, but I think that it is not the best solution.

Sound and TV setup

Im setting up my home media machine and I plan for the sound to come out of the TV (as well as the picture).
What types of connection do I need for the audio and visual to come out of the TV?
My TV has VGA/HDMI and all of the other inputs a hd tv has.
Many thanks.

I would use the HDMI. Your picture won't need to go through an analog stage and it transports the audio as well.
On my HP Pavillion DV4 I had to fight with gstream to get the audio to go where I wanted it to go. I ended up using PulseAudio, Jack and the Xine backend for Phonon.
The sound and audio on a 1080p display is amazing.

Audio noise and echo

I need to get rid of or minimize some noise in an audio clip in Final Cut Pro. There is also a bit of echo in it that I would like to minimize or eliminate as well. Also, if the solution to this requires frequencies or things of that nature, could someone give me a idea of what frequencies I could use. Even a range would help. Thanks!

Hi - Try this:
Go to the Effects Tab
Audio Filters>Final Cut Pro and select the filter Expander/Noise Gate
Drag that filter on to the audio clip you wish to try and improve.
This filter works by making loud sounds louder and soft sounds quieter, so when you use it the background sounds and echos should be reduced.
You adjust it by double clicking on the clip which you applied it to, the clicking on the filters tab.
Adjust the filters effect by adjusting the Threshold control. I would nudge it up until it become objectionable.
This is processor intensive so you will probably need to render the clip after each adjustment to hear it play back.
Select the clip and hit Command -R.
Hope this helps.

Distorted sound from some CDs on Pavillion dv6

Approx 5% of my CDs have a distorted sound and are unlistenable. It is nothing wrong with the CDs, they play alright in my Lenevo T61 or McBook Air. The CDs are both new and old. It is the same using iTunes or Windows Media Player. Anyone experienced this and is there any solution?

Hi,
First, try the automated fixit from Microsoft on the links below.
Windows 7
Vista
Check if your CDs sound ok now.
If they don't, from the Start Menu, open the Control Panel and click on Device Manager. Click to open the IDE ATA/ATAPI Controllers. Right click on the first channel and select uninstall. Do not delete drivers if asked. When uninstalled repeat the process for each channel. Also if an ATA controller is listed, right click and uninstall this, again not deleting drivers if asked. Then open DVD/CD-ROM Drives. Right click the drive and select uninstall. Do not delete drivers if asked.
Reboot the PC and let Windows reinstall the devices. Check the sound from your CDs again.
If it still doesn't sound ok, run the automated fixit from Microsoft on the link below again.
Windows 7
Vista
Next, from the Start Menu, open the Control Panel and click on Device Manager. Next click to open DVD/CD-ROM Drives. Right click the drive and select uninstall. Do not delete drivers if asked. When the device has uninstalled click on the 'Scan for Hardware Changes' icon ( usually just below Help on the toolbar ). Let windows reinstall the drive and see if your CDs now sound ok.
Hope this helps.
Best wishes,

How to create a 'parallel' extended display through Apple TV Airplay

Dear all,
I'm a relatively new Mac user and have not been able to find an answer to my question by looking up key words in Google or here, so apologies if this has been answered before.
Basically, I would like to know how I can project a video file or a film/TV series I am watching (for example, a video playing in VLC or a film streaming from my subscription to Amazon Prime Instant Video website, open in a browser) onto my Toshiba TV, via Apple TV airplay - whilst still being able to work on a separate window/desktop on my MacBook Air.
As a PC user slowly converting to Mac, I know how to do this on a PC by using the Windows logo key +P shortcut, choosing 'Extend' instead of 'Duplicate' and then dragging whatever video source I want to watch into the extended desktop screen being projected on my TV. I've tried doing this on the Mac by
using the multiple desktops in Mission Control (with no success, as Airplay obviously just mirrors what I'm doing on my screen onto the TV, i.e. switching from desktop to desktop as I do on the computer), or
by clicking 'Extend Desktop' instead of the automatic 'Mirror Built-in Display' on the Airplay icon on the menu bar and then dragging the browser into the extended display on the TV and hitting the 'Full screen' button of the video itself. However, as soon as I do this and click or type anything on my computer desktop, the video automatically minimizes and all I'm left with on the TV display is the browser with the initial smaller version of the film playing within it. In the 'View' tab, I've tried switching Firefox/Safari to 'Full screen' before making the video 'Full screen' too, but again, as soon as I touch anything back on my Mac desktop it minimizes. I've noticed Chrome has an 'Enter Presentation Mode' option available in the 'View' tab, which leaves the video playing full screen, but with a grey bar at the top (which is visually annoying, but still closer to what I'm looking for). Similarly, if I try to drag a video file playing in VLC, as soon as I hit the full screen button, the desktop I'm using on the Mac goes black even though I can still move the cursor on it.
I'm clearly missing a step somewhere, so any help would be greatly appreciated as I'm a prolific multitasker!

Hi _MicMacs_,
It sounds like you've been on the right track in trying to sort out this issue. I'm a bit unclear on what you are describing when you say it works initially, but then immediately reverts when you click back on something in your primary display. You may want to try sizing the window to the display instead of using the full screen option (two opposing diagonal arrows), though this will leave the window border around the screen. For a bit more background on working with multiple displays in Mavericks, you may find the following article helpful:

Airplay mirroring on Mac Mini (late 2012) doesn't work, extended display does...

Airplay mirroring on Mac Mini (late 2012) doesn't work, extended display does... What's going wrong here?
Details: OS X Yosemite 10.10
Apple TV 3rd generation, version 7.0
Switching Airplay on on Mac Mini works. It goes automatically on extended display mode. Switching to mirroring works for about 1 sec and then it switches back to extended display mode. On my tv screen i see my second desktop. Funny detail: it has the desktop background i used previously. Another funny detail: I had exactly the same problem when i used the previous versions of OS X and the Apple TV software...
Who can help, please!

I also have been having problems with Airplay on my 2014 Mac Mini see Mac Mini 2014 Airplay Display Disconnect Bug?
I"ve also noticed that my Apple TV (3rd Gen) does not appear in the iTunes Airplay list on my Mac Mini whereas it does on my MacBook.
I've booked a call with Apple Support for next Sunday to discuss the issue.
If I get any useful info I will pass it on.

Buzzing and Echo Sound After Recording

Hello,
I am hearing a buzzing and echo sound in the background after I record a project on Captivate 4. I am using a USB DYNEX Microphone that is connected to the Laptop. Adjusted the Volumne in Captivate but does not elemintate the background noise. Any suggestions???
Thanks

Have you looked for environmental noises, both electrical and audible?
Here are some possible culprits for induced electrical "buzz" or "hum." These "noises" are actually created by electrical interference in the recording equipment, and don't become apparent until playback:
Fluorescent strip lighting.
AC power cords near the microphone cable.
Mic cable near CRT displays.
Other electronic devices where you are recording.
If you're using a laptop, I find I have better luck running on battery power when recording, though I'm not clear if this is because of the power source, or because power-save features kick in that make the machine quieter.
Another possibility is real audio noise that you mentally tune out when you're in the room, but hear when you listen to playback. Some ones I've run into:
Ventilation noise. Particularly if you're recording in a building where you work all the time, you don't hear the ventilation system unless you really stop to listen for it.
Small electronic devices -- fans, projectors, etc. that might be in the room.
Also, play around with microphone position relative to your mouth; it's possible that the source of the racket is your own breath!!
Good luck!!

HP ENVY TouchSmart 4 Ultrabook - Sound and Video Lags and Distortions

This issue has been previously reported and noted as solved, but it is not solved. See the link to the other post below.
Ways in which I attempted to address this myself...
I first re-installed all drivers and updates, including BIOS updates. After that didn't fix the problem, I did a full wipe/re-install of windows 8, and again, updated all drivers from the HP website. This issue happens on both Windows 8 and Windows 8.1. I then did an exchange, and even the new exchange ultrabook is experiencing this issue. HP technicians, there is something faulty with this device. Please acknowledge and address ASAP.

I have the same mini display port adapter and Belkin DVI-HDMI cable (but a Panasonic 42" Plasma HDTV) so just set this up on it to see if I could duplicate your problem, unfortunately for you (but good for me) I can't.
I connected the adapter+HDMI cable before switching the HDTV on and then powered up the MBP. It (the HDTV) came up with my background right away (it's set at Mirror not extended Desktop) and when I run System Preferences/Displays get the following. Sorry but all I can confirm is that adapter+cable combination should work ...
Try doing a Parameter RAM reset - hold down command/option/p/r keys at start up and wait for three chimes before releasing the keys?

I can hear both a clean sound and distortion at the same time.

I can hear both a clean sound and distortion through my monitors and headphones. I am playing into a Presonus USB and directly into a MacBook Pro. Any idea how I can get rid of the clean sound?

You probably have a mix knob on your interface that switches between dry and wet signal. The knob should mix the signals.

Hi jaredfox06,
If I understand the issue correctly, you have recently purchased a used iPhone and you do not see your Apple TV in the control center in order to AirPlay. To troubleshoot this issue please follow the steps outlined below.
Try these steps first
Make sure that you have the latest software on your iOS device and Apple TV.
Make sure that both devices have Wi-Fi turned on.
On your iOS device, go to Settings > Wi-Fi.
On your Apple TV, go to Settings > General > Network.
If you're trying to use peer-to-peer AirPlay, make sure that both devices have Bluetooth turned on.
On your iOS device, go to Settings > Bluetooth.
On your Apple TV, go to Settings > General > Bluetooth.
If you don't see AirPlay in Control Center
When an AirPlay-enabled device is available, you'll see AirPlay in Control Center on your iOS device.
If you don't, try these steps:
Restart your iOS device and Apple TV.
Connect both devices to the same Wi-Fi network.
On your iOS device, go to Settings > Wi-Fi.
On your Apple TV, go to Settings > General > Network. If your Apple TV is connected using Ethernet, make sure that it’s plugged in to the router you're using for Wi-Fi.
On your Apple TV, make sure that AirPlay is turned on. Go to Settings > AirPlay.
