Issue: Playback devices window

Re. Toshiba Satellite L755-S5277
Issue: No audio over HDMI cable.
Regular Toshiba W7 Home original Toshiba software re-install from HD.
Observation: Playback devices, shows only "Speakers Conexant Smartsudio HD Default Device", and nothing else.
Questions:
1. Is there supposed to be anything other than "Speakers Conexant Smartsudio HD Default Device" in the Playback devices window ? Yes / No
2. If yes, then what ?
Thanks.

Jerry,
Your suggestion to reinstall the Intel Display driver was very helpful.
Thank you.
In the playback window, now appears "Sharp HDMI...",
and now I have audio at the TV, but I have to disable the "Speakers Conexant..."
in order to get the sound to stop coming from the laptop,
and instead come from the TV.
Previous to the Audio problem, this was somehow happening automatically
whenever I connected the HDMI cable, now I need to manually disable the "Speakers Conexant...".
It there some configuration that would make this process automatic again ?

Known issue: Cortana does not play audio through the default playback device (Windows 10 Insider Preview SDK and tools, April 2015 release)

When getting audio feedback from Cortana on a device with multiple playback endpoints (e.g., a device with a headset and an internal speaker), the playback may occur on the incorrect device. For example, Cortana may not send audio to the default device
after the default has been changed in the control panel.

There is no workaround for this issue.

Problem with Playback device on windows 10

Just today i downloaded the new Windows 10 update and i like it for the most part. But i went on skype today for a video chat and a pop up came up saying that i have a problem with playback device and i cannot video or voice call. skype worked fine yesterday on windows 8, need solutions ASAP.

Do minimize the chances of having issues with other audio/video devices: 1. Uninstall Cyberlink Webcam Splitter. It my not work properly in Windows 10.2. Disable Stereo Mix. You can also download and install the latest Realtek Driver suite even if you have the latest/same drivers installed. The suite can resolve issues. Download and install the latest generic Realtek audio drivers (High Definition Audio Codecs - 64bit Windows 10)http://www.realtek.com/downloads/ I've outlined most of the causes and solutions here:http://community.skype.com/t5/Windows-desktop-client/Problem-With-Playback-device/m-p/3356467/highlight/true#M282763

Is there a way to select a specific playback device while using itunes 11 on Windows 7?

Is there a way to select a specific playback device while using itunes 11 on Windows 7? I was trying to select a device, is there such an option in itunes as there is in VLC player and Windows Media Player. If not, any idea when this feature will becoem available? Thanks!

iTunes supports multiple Airplay devices that can be selected. If the device does not support Airplay then the manufacture of the device would need to support it for iTunes.

Windows 10 updated - Skype problem with playback device

Hi, please advice on how to correct the error with Skype - problem with playback device.I have updated all drivers

Please, run the DirectX diagnostics tool (32-bit). Run dxdiag.exe (Start - Run or Win key +R) then press enter or click "OK". Once the diagnostics completes, "Save All information..." to a text file.

No HDMI Audio, Failed to Play Test Tone, Can't Change Default Playback Device

Hello, I'm experiencing some real trouble with my HP Pavilion dv6-2160us (with the i3-330M, no dedicated graphics) Windows 7-64 bit, SP1 PC, and I would greatly appreciate some assistance.
I've created a new thread because, despite the fact that many other people have experienced a problem similar to this and have posted what worked for them, nothing has worked for me.
The Problem(s):
My main problem is that I cannot get any audio to play from my PC to my HDMI HDTV.
When I plug my HDMI cable into my PC and TV, the TV is recognized in Playback Devices, but nothing can play to it.
When I try to test the TV in playback devices, I get a "Failed to play test tone" error.
Additionally, I'd like to mention some other odd behavior that I think may be a part of the main problem.
In Playback Devices, I cannot change anything. I can't disable or enable a device, I can't set default playback or communication devices, and I can't save changes inside device properties. Every time I try to change something, like the default playback device, nothing happens or the changes are immediately reversed.
The Question:
How can I get audio to play over HDMI on my PC (It's not a problem with the TV, my other HP machines play audio over HDMI to it just fine.)?
What I've Tried:
I have tried:
Changing the default playback devices, which I'm unable to do
Running the Windows 7 Audio Playback troubleshooters from within a clean boot state
Uninstalling and reinstalling the Intel(R) Display Audio driver
Uninstalling and reinstalling the IDT High Definition Audio CODEC
Uninstalling the IDT PC Audio program from Programs and Features
Disabling the IDT High Definition Audio CODEC
Nothing has worked.
The drivers I have are the latest issued by HP
How can I get this working? I would really appreciate some assistance.
I'm at the point where I'm ready to try pretty technically-involved suggestions, so, please feel free to post those.
Your expertise is greatly appreciated.
Thanks.

The Hp pavillion dv6-4023Tx notebook is connected through hdmi to my blueray surround sound which is connected to my tv.
Please help

@Camilad
I hope you have and had a wonderful holiday.
Okay for your sound problem, it is possible that something else may have been inadvertently deleted when you disabled the Bluetooth. It is hard to say for sure.
I did find this page which is directly related to what you describe. In it is mentioned driver updates and BIOS updates.

Here also is the driver page for your notebook, where you can find those that you need.

No Digital Output available in Playback devices (USB audio device)

If one has USB audio device with coax/toslink out, with proper drivers (like ie TurtleBeach Micro Advantage) available & installed then Digital Output is available to select in Playback devices. (and one can play AC3/DTS to external amplifier with ie
VLC or MPC-HT with AC3Filter DS filter)
But some USB devices (ie Phonic Digitrack -
http://www.phonic.com/en/digitrack.html ) do NOT come with drivers (as Windows has default build in). Digitrack uses TI
Burr-Brown USB Audio Codec 2906 -
http://www.ti.com/product/pcm2906
Sadly these Windows drivers do NOT have a clue about what the device actually has as inputs/outputs
So even it had coax digital out & the sound IS send via it, the actual data send is in right way, not recognized/played correctly by Digital Amplifier (AC3/DTS)
Does anybody know of a hack to make Digital Out available?
Seb

Hi,
Generally speaking, An Audio Device do need more driver besides USB driver to make itself work properly. In terms of your situation, USB driver is not enough to make your Audio Device works properly. I think S.Sengupta
is right. Actually it would be better to contact Digitrack support to confirm its product compatibility with Windows 7.

No Sound Device/Playback Device --At the end of my rope

First let me state that I've tried several methods to fix my problem already, and none appear to help or work, I've followed the advice given by several others, and I'm really not sure what I can do at this point. I even bought a new Soundcard thinking it would solve the problem...but it has not.
If I were to go into Device Manager right now, Windows detects TWO Audio Devices:
Soundblaster Xi-Fi Extreme Audio
Vinyl AC '97 Codec Combo Driver (WDM)
The latter I can easily disable in BIOS on Startup, but this does not help me one bit.
I have checked my Sounds and Audio Devices:
No Audio Device/No Playback Device/Sound Recording is Soundblaster/Midi is Creative SoundFont Synth/No Voice Playback/Voice Recording is Soundblaster.
I have checked my Services (Local):
Windows Audio Service is "Started" and set to Automatic?
I have checked other media devices and get errors regarding "Direct Sound" or "Wave Out".
Regarding the programs related to my drivers, I have tried to uninstall them and reinstall them in Safe Mode but this has not helped. In particular one of the programs VIA Audiodeck (related to my onboard audio) cannot seem to find certain files to uninstall itself, aside from the fact it couldn't run when I installed it in the first place. (In part I'm looking for a free program that can uninstall stuff that can't be uninstalled the usual way).
Finally I've discovered I'm getting errors in trying to check for Windows Updates (even though I have Service Pack 3 now). Windows Automatic Updates says it's "On" but doesn't show up.
I don't really know what the root of my problem is, as I've tried uninstalling and reinstalling my drivers several times (even attempted to?clean up the registry from leftover fragments). I've used programs like Belarc Advisor and Driver Scan but these don't tell me what to do or how to proceed. I'm at my wit's end here.

I'm not sure what anyone here can do
Nothing. These are user to user forums, of which Apple employees do not take part in.
Does anyone know who I can EMAIL about this,
Nobody...Apple does not offer email support/correspondence. Call support and ask immediately to speak to customer relations.

Loss of sound due to no playback devices following an system update.

I have a Model #: 23-c055, Product #: H4A31AA#ABA. My machine was updated over the weekend with an automatic update and now my playback devices for both video and audio are gone. The selections within Device management are not available for selection to modify. HELP!

Nina, welcome to the forum.
You should go into Control Panel / Sound and check to assure that your sound device is selected as the Default. This is most likely what has changed. Here is how to reset the default device:
Instructions:
1 Press the "Windows Key" and "R" keys simultaneously to load a Run box
2 Type "mmsys.cpl" and click "OK." This loads Windows Sound and Audio.
3 Click the "Sound" tab.
4 Click the drop-down menu under "Sound Scheme" and select "Windows Default."
5 Click "Apply" and then "OK" to save the changes.

Bluetooth headset pairs, but is not available as playback device

Hi there
I am trying to pair and use my MEElectronics Runaway bluetooth stereo headset (with microphone) with my Zbook. I am following the instructions at MEElectronics available here http://www.meelec.com/Articles.asp?ID=352#ytplayer
I make the device discoverable and am able to pair the devices.
I select the device in Windows and it says 'connecting to device' then 'configuring device'. Then
'This device has been successfully added to this computer. Windows is now checking for drivers and will install them if necessary. You may need to wait for this to finish before your device is ready to use. To verify if this device finished installing properly, look for it in Devices and Printers.'
I click on Devices and Printers, and find the Air-Fi Runaway.
I click on volume system icon to select it as a playback device, but it is not listed there.
How do I guarantee that Windows actually downloads and installs the drivers to make this work? It doesn't appear to be doing so automatically as per what happened above.
Thanks in advance for any assistance you can provide.
Tronica

hello,
the reason the driver is not installed is because there is no windows 7/8 64bit driver available .
I have the same problem with another kind of headphones, soundpeats qy7 .
I keep searching and hoping that maybe a driver will be completed and published .

My mac desktop will not provide sound from internal speakers. when I go to audio devices window it only shows airplay. How can I get internal speakers back.

There are many possible causes for this issue. Take each of the following steps that you haven't already tried. Some may not apply to your model. Back up all data before making any changes.
1. Start with the steps recommended in this support article. Don't skip any of the steps. It's the starting point for further efforts to solve the problem.
2. Run Software Update and make sure you have a fully up-to-date installation of OS X.
3. If you've installed an application called "Memory Clean" or any other third-party software that is supposed to "clean" or "purge" memory automatically, remove it according to the developer's instructions and restart. You should do that even if the software is not causing the problem, because it's useless.
4. Other third-party software that has been reported to interfere with sound output includes "Boom" and "Samsung Kies." If applicable, uninstall according to the developer's instructions (not by dragging something to the Trash.)
5. If an AirPlay device is selected for sound output from iTunes (or from other applications via third-party software such as "Airfoil"), deselect it.
6. Launch the application "Audio MIDI Setup" by entering the first few letters of its name in a Spotlight search and selecting it in the results (it should be at the top.) Select Built-in Output from the list on the left. If the Mute boxes are checked, uncheck them.
7. If a red light is visible in the audio-out port when sound should be playing, the internal switch is stuck in the position for digital output. You may be able to free it by inserting and removing a mini-stereo jack of the proper size. Inserting any kind of tool in the port may cause damage that won't be covered by your warranty.
If there's no red light, the switch may still be stuck in the headphone position. Try to free it the same way.
8. Disconnect all wired peripherals except keyboard and mouse, if applicable. If more than one display is connected, disconnect all extra ones. Restart and test.
9. If you have a MacBook Air, turn off Bluetooth and restart.
10. Start up in safe mode. Don't log in; just restart as usual when the login screen appears. When you do, make sure the words "Safe Boot" do not appear in the login screen. If they do, the system is still in safe mode and sound won't work.
11. Reset the NVRAM.
12. Reset the SMC.
13. Triple-click anywhere in the line below on this page to select it:
/Library/Preferences/Audio
Right-click or control-click the highlighted line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash. Recreate your settings in the Sound preference pane.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
14. Reinstall OS X after backing up all data.
15. Make a "Genius" appointment at an Apple Store.

How do I get Independent Headphone to be the default playback device in Beats Audio?

In the Beats Audio control panel (I own a Pavilion dv7-4051nr) the only option listed for Independent Headphone is default communication device. The only time I have been able to enable Independent Headphone for sound playback was through Windows Media Player (Tools>Options>Devices>Speakers>Properties). I thought the audio was superior and played louder compared to using the Speakers and Headphones as playback device for headphone listening. However, the next time I logged on and attempted to play a CD with Independent Headphone there was no sound output despite the fact that the Independent Headphone volume control on the taskbar indicated it was working. When I switched to Speakers and Headphones, sound was delivered to the headphones as normal.

Problems with Playback Device ?

Im using Skype for desktop and it doesnt make the noises when I receive a message. I tried checking if the noise all together wasn't working and when I tried called the Echo / Sound Test Service it told me there were problems with the playback device. The sound works fine on other apps it's just that it doesn't seem to work on Skype. I went on the sounds tabs in the options menu and I selected the correct device to play the sound with but it still won't work. I am using an ASUS laptop.
