No audio output while charging

I can't seem to use adio output while Ipad is charging

Hello there Pedro, please forgive me for my late reply, I was unable to test meanwhile,
and yeah, I removed the battery and booted my laptop with AC power. Result : the same sound.
I also noticed that, If i listen closely my charger unit, i can hear the same sound from the charger too...(It's obviously the same, but a hoarse noise)
Afterall, It's not distorting internal speakers, that happens when i use the line out for my amplificator.
Whenever I plug it out, I have no problem such as an annoying distortion voice on line out jacks.

Tecra A3 106 Noise on Audio Output while Charging

Hello all,
My Tecra A3 generates an annoying noise on line out/headphone output while charging the battery.
when it's unplugged, the noise goes off.
Is that normal?
Thanks in advance.

How to set correct audio output while using external screen for presentation purposes over a wire

while trying to make a presentation or simply playing a video from my MacBookAir over thunderbolt/HDMI table to large screen I am experiencing problems with audio only being played from the MBA and not the soundsystem built in to that screen (unless using a VLS application and manually selecting the audio output target).
Please help in finding how to steer audio output device using 2in1 cable such as thunderbolt?

Hi jar9,
If you are not hearing audio over your HDMI/Thunderbolt connection, you may want to see if it is showing up as a selectable audio output as outlined in the following article:

Airplay - use built-in audio output while mirroring

Yesterday I tried to configure my headless mac mini to use airplay mirroring to my ATV3. This in general works beautifully.
The thing is, I use this machine as hifi-transport and want to continue using the local audio output (S/PDIF / Toslink / USB DAC) during mirroring.
I could not find any way of doing this. in Audio MIDI mixer, the sound output switches to Airplay as soon as I enable mirroring. If I then use the Audio MIDI utility to switch back oudio output to the built-in output, it automatically deactivates the mirroring session.
Even creating an aggregate and/or multiple output audio device in Audio MIDI utility and put together Airplay output and the built-in output, it does not work...
Anybody have any idea how to solve this?

I like to chime in on this one too as I was just about to create a thread of my own.
My current home situation:
living room: airport express connected to receiver
work room: macbook pro with mountain lion in combination with Spotify
I would like to have the sound of spotify be sent simultaneously to the optical out of my macbook and the airport express in the living. So I created an aggregated device using this support file: http://support.apple.com/kb/HT3956# - i ticked the box on both AirPlay and Built-in Output but there is no sound getting transfered to the Airport Express.
If I only tick the Airplay checkbox it works perfectly in the living room and if I only tick the Built-in it works perfectly on the macbook. But not both checkboxes combined.
Screenshots for clarification to be found here: http://imgur.com/a/K0KND#0
screenshot 1) works as intended: sound on airport express via AirPlay
screenshot 2) does not work as intended: only sound on macbook pro
screenshot 3) works as intended: sound on macbook pro via Built-in output
So any clue why the setup from screenshot 2 does not work?

Audio Output while using Airplay

I have a rather unique requirement that has me stumped. We have an Apple TV driving a projector that does not have audio output so when we mirror the display from the iMac using airplay we want the audio output device to be "Internal Speakers" but that can not be selected in System preferences. Does anyone know a work around for this configuration or will I have to get seperate amplifier and attach it to the optic audio output from the Apple TV?
Thanks
Brian

Well, since I can't imagine this being a feature of Airplay I assume we're either hitting the limitations of the technology, or it's a bug. Knowing Apple I suspect it's a limitation of Airplay, perhaps because audio and video are sent out as an integrated stream?
I agree, this does suck, since all I have to use as audio is the tiny 1 watt speaker on my Epson projector! I can't even use audio out from the Apple TV, since all it has is that useless optical port. Very frustrating indeed.

Is there a way to have Firefox respect the default audio output device when it has been changed while Firefox is open?

I have been a Firefox user for many years and I still use it as my primary browser. One problem that has bothered me for years is the fact that when Firefox is open and I change my default audio output device, Firefox doesn't respect that change and continues playing audio through the device that was originally being used. Even if you stop the audio and continue playing, the output device doesn't change.
Is there any way this can be configured in Firefox? Now if I listen to music online (e.g. Soundcloud) I always use Chrome since it's respects the default audio output device change even while in the middle of playing audio.
Reproduce:
1. Start playing audio (e.g. from a YouTube video; HTML5 and Flash are affected)
2. Change your default audio output device
3. Audio will continue to play from original output device
Thanks!

This is the same issue that has plagued me for years. I always thought that this was a Flash plugin issue, but it does occur on HTML5 as well. A friend of mine verified that this does not occur in Linux, but only on Windows. It would be great to have this fixed, as it's honestly the only thing that's making me use Chrome all the time, as I don't want to have multiple browsers open.

How to get audio output of my instrument while playing back the other tracks?

I do not hear any audio signal from my bass guitar while playing along the other tracks in Logic. I can only hear the audio output of my bass while I record or stop the music. How can I change the settings so that I can play along and hear myself while I practice? The track for bass is not muted and is getting a strong input signal.

How to disable audio output in while in sleep mode? (annoying issue)

I have a my workstation set up in my bedroom and when I am not using it I put it to sleep (or wait for it to go to sleep deu to inactivity). The problem is that when its asleep the audio output is still active. So when I get emails and such the speakers still emit the notification/alert sounds even though my computer is in sleep mode. This is really annoying since I work with offshore teams and they send me email in the late night and early morning (when I am sleeping). I can't seem to find a setting to change that. Any ideas?
My set up is as follows:
17 macbook pro (early 2011)
OSX 10.9.4
Connected to a 27" thunderbolt display
Thanks!

Thanks KiltedTim. I am starting to agree with you. Do you know what I can log for in the logs that will give me an idea?
Esquared - Thanks for the link. The only thing I see in the logs is when I woke up my computer this morning. But all morning (before I woke my computer) I was hearing a bunch of alerts/notification. Here's a look at the log query I did.

W500 audio noise while using audio output

Hello,
Few months ago I've bought Lenovo W500. After some time realized that when I'm using an audio output in sometimes I can hear annoying noise. I've checked it with different headphones (also professional ones) and other audi equipment. Always the same.
In the beginning I've thought there are some problems with my Alsa configuration (I'm using mainly Linux) but havent time to check.
Now I've spent more time for that. I've couldn't find solution, decided to check on Windows also - there is the same problem (with exactly the same audio files/youtube videos etc.)
Checked with different quality audio files - mp3, flac, audio cd etc. Always the same.
I can hear it very good in this moovie:
http://www.youtube.com/watch?v=SaUL_7H7r40
first time noise appears at 00:02 - 00:03 and then I can hear it in almost whole time.
If I turn off all audio players etc. I can still hear annoing, quiet noise from headphones (on both OSes - Linux/Windows).
Has anyone simmilar problem?
Any solution? My W500 is ofcourse under warranty but I need it at the moment very hard, so I hope there is some solution different than sending it to service :/
Thanks a lot,
Regards.

If you discard any software related problem, your problem is over hardware.
The only solution is sending to service and the will repair it for free. Maybe the will change the entire motherboard.
Best regards.

Audio output no longer works

I have a new Mac Mini that I got up and running about a month ago. A couple of weeks ago I installed a bluetooth device, a headset I also use with my celular phone, to use with Skype. So far so good....but when I tried for the first time to fire up GarageBand, sound output was setup to go through the headset. So in preferences -> audio output, I selected "Built-in audio". From this moment on I haven't had any audio output at all. I turned off the headset, restarted GarageBand, and got "bluetooth audio failed", tried a reboot, tried deleting the bluetooth device and turning off bluetooth, rebooting again, and still no audio. Other audio applications work fine--sound from games, media, etc. come out the built-in audio. But Garageband still is silent. In the preferences there are no more references to the bluetooth hardware in the drop-down lists for the audio devices.
Does anyone know how to fix this? I have been searching the discussions and Apple knowledge base artices for a while and can't find anything.
This is GB version 2.0.2 (50).
Thanks for any help!
Bill Nassauer

In the system prefs, under "Sounds", the only device listed is "built-in audio", and it's selected. I've already setup the GB prefs, and they're still fine (see my original message). I've never played with the audio midi setup, but taking a look for the first time, it looks normal--properties are shown for "built-in audio", and that's the only possible selection...nothing muted, and volumes normal...

No variable audio output for Cisco CHS 435HDC set top box.

Background: Until the other day I had my stb connectected to a TV, using TV sound, with an HDMI cable. The P265v2 remote volume control changed the TV volume. No problems.
My new TV & home theater system was recently installed. We don't use the TV speakers. While my first preference was to program the Verizon remote to change the volume on my Onkyo receiver, this did not appear to be an option on the remote's programming instruction page on the Verizon website. Instead, I am directed to change a setting on the remote that makes the Verizon remote change the stb output volume vs the tv volume. I changed the setting on the remote and ensured the stb box was set up for "variabe" audio output.
Problem: Using the stb variable audio settings, volume settings 1 through 30 produce the same volume. (Volume setting 0 produces no volume, as one would hope.) It appears the "variable" setting isn't producing a variable output as it should be on this unit.
Thinking that maybe the receiver was complicating the sitation, I tried connecting the stb to the old TV and the new TV directly and had the same results.
Now, while I am watching TV, I need to have the receiver remote at hand in addition to the Verizon remote. It would be nice to have the volume be adjustable as it should be while using the Verizon remote. I don't like the idea of using a seperate universal remote because then I would lose some of the functionality that the Verizon remote provides when watching TV, using the DVR, watching on demand, etc.
I would like to know if this is a problem just with my unit, or if it exists with all of these units, which would hopefully be fixed with a Cisco/Verizon firmware update soon, hopefully.
Thank you.

Having same issues with hdmi and optical. Any fix to this.
Hello,
In order to control the volume on your home theater system, you'll need a FiOS TV Universal Remote that has the 4-buttons on the top for 'DVD', 'Aux'iliary, 'TV' and 'STB'. The audio receiver would have to be programmed into the FIOS TV Remote, and controlled using the 'Aux'iliary button.
Verizon's 4-Button Universal Remote Controls are available for purchase:
a) online via www.verizon.com/fiosaccessories
OR
b) at a local FiOS TV store (call first to check if they have them in stock). For a list of stores: http://www22.verizon.com/support/residential/tv/fiostv/general+support/account+issues/questionsone/8...
Presently, the default remotes for new set top boxes are the 2-button P-265 (newer version) remotes.
Regarding a problem with HDMI/optical on Cisco 435 STBs, check out the following:
Go to this webpage: http://www22.verizon.com/Support/Residential/TV/FiOSTV/Receivers/Equipment+Issues/QuestionsOne/12839...
Click on the link for 'Cisco CHS 435 HD DVR User Guide'.
Open the PDF and go to page 22 for 'Connecting to a Home Theater System...'.
Hope this helps!

How can you choose which audio output device to use?

I currently have my system set up to have two different active audio output playback devices, Speakers and Headphones. By default, applications play on the default audio output device, which is set to Speakers on my computer. However, I am wanting to play iTunes on my Headphones output while all other applications are running on the default Speakers output. In Windows Media Player, there is a dropdown to select which output device the application streams to. Is there a way to make iTunes do this, either in the Preferences menu, by using a plugin, or installing a third-party application that overrides which output applications use?

Under Utility you will find the Configurazione MIDI Audio.app The name is in italian on my Mac but you should find it in your system language. The icon is a Piano Keyboard.

Is there no way to direct an AIR app's audio to different audio output devices?

I'm needing to make a couple of our AIR apps select certain audio devices to send their audio output to, and last year, somebody mentioned possibly using native extensions to do this. I had to start working on other things for a while, but I've come back to this (for the moment), and I've basically learned how to create native extensions.
But so far, they don't seem to provide me any special access to anything going on under the hood of an AIR app. When you stream live audio in through RTMP or RTMFP, the details of the audio are hidden from you. There doesn't appear to be any place where you can actually access the audio bytes that are being sent over the wire. You can specify a certain SoundTransform object for the NetStream to use, but that class is final and a vanilla Flash construct, so even if it may have a way to access the audio bytes, they're not acessible at all.
It really looks like, when a NetStream object starts streaming in live audio, there is no way under the sun to access the audio bytes and direct them to a certain audio output device, with or without extensions. Is this so? It would be unfortunate if Adobe didn't allow this, even through native extensions. Thanks.

Couple quick thoughts..
Limits are important. There's a large amount of work done to keep a clear separation between a users decision and a developers decision. For instance, you can't change a users default audio output because that clearly violates a users decision. That said, here's a whole mess of people debating the issue and actually eventually an undocumented COM API you can find that will actually let you do it in Vista/Win7 (but not 8), however don't expect that to be a 'good thing to do':
http://social.microsoft.com/Forums/en-US/9ebd7ad6-a460-4a28-9de9-2af63fd4a13e/programatica lly-setting-the-default-playback-device-and-recording-device?forum=windowspro-audiodevelop ment
You might want to get a beverage before reading that.
Aside that, RTMP is secured, which is why you can't gain access to the bytes. The entire purpose of it is to assure media developers that their media can't easily be copied/stolen. Adobe doesn't document their method of securing streams but they do publish the RTMP specification. It's entirely possible for you to create your own RTMP server and encryption method while delivering a RTMP stream to custom client that you code yourself which can read the stream. Here's the spec:
http://www.adobe.com/devnet/rtmp.html
So I'd say it would be unfortunate if Adobe did give you access to the bytes. You might as well just hand users a mp3 of whatever song is playing because they would steal media left and right.
That isn't to say you can't use a multitude of ways of getting the data going across the default output device. Plenty of apps (fraps/etc) capture video and mixed audio streams. But Adobe isn't going to give you the keys to the kingdom and let you decrypt their protected media protocol.

Why is my left audio output not working, when I have brand new headphones? (6th Generation Ipod Nano)

I have recently been having problems with my Ipods audio output... The Left headphone puts out No sound at all... I am positive it is not my headphones... Any solutions or is it a harware problem??
Hope to hear Back ASAP thanks

iPod Nano Touch? (I must have missed the announcement of that model of iPod!)
Regardless of which model of iPod you have (and if it's a Nano, why submit your question to the Touch forum?), some car charging devices charged iPods via the firewire line, which was fine for the first iPods on the market. Some later iPods charged by firewire or USB. New iPods do not have firewire and cannot be charged by firewire. They only charge by USB
So perhaps your old iPod (again, whichever model it is) charged by fireware.

No audio output device is installed - Satellite C855D-S5950 - Windows 8 64-bit

Hello,
I have my friend’s Toshiba Satellite C855D-S5950 with Windows 8 (64bit) that about a year old. Some months ago the sound stopped working. He asked me to take a look at it. I have researched this issue and found others have encountered his problem as well.
Currently, the sound icon has a red x, “No audio output device is installed.”
Things I have tried so far to try to fix this:
I went to the Device Manager > Sound, video and game controllers. I have "Realtek High Definition Audio" listed with the little yellow caution icons on them. I have tried to disable, then enable it. I have tried to uninstall the sound driver from the Device Manager. I would restart the laptop, and let the driver reinstall itself, to no effect. I have tried downloading the latest drivers from the Toshiba website. I have tried un-installing the driver while in safe mode from the Device Manager. As well as from Programs and Features. There were no positive change to the audio though, still the same message. The Realtek driver won't finish installing and throws the error: "Install Realtek HD Audio Driver Failure!! [Error Code: 0x000000FF]"
I have gone to Control Panel > Sound, under both the Playback and Recording tabs, it says "No audio devices are installed."
My friend was previously unaware of how to restart or shut down his Windows 8 laptop (as was I until I started investigating this problem for him). I mention this because there are no useful System Restore points to go back to for him.
I have also tried Using the Toshiba Application Installer as well to re-install the driver after un-installing the Realtek Audio driver from Add/Remove Programs. I went to Desktop Assist >Support Recovery > Toshiba Application Installer.
Realtek Audio Driver 6.0.1.6743
It loads most of the way then I get:
"Install Realtek HD Audio Driver Failure!! [Error Code: 0x000000FF]"
I have also tried the following links for additional troubleshooting:

It was also suggested in the above thread I remove the Microsoft UAA Driver, but could not find this driver on my friend’s system.
Plugging in headphones, toggling the speaker volume controls on the keyboard has had no effect.
My friend has also misplaced his install discs, so I am looking for any solution which does not require the install discs.
Any help would greatly be appreciated.

Recovery media is created from the hard drive. You can make it using Toshiba Recovery Media Creator. You can also perform a full system reset to factory defaults using the information on the hard drive without using external recovery media. That sounds like the best course of action now. To do so, use Windows+C > Settings > Power > SHIFT + Restart > Troubleshoot > Reset your PC.
