Windows does not recognize tv as audio device after it has been turned off and turned back on.

I have my computer hooked up to a HD TV with the HDMI cable.  The sound also pretended on television.  The HDMI cable is connected to my Radeon HD 6950.  I use Realtek HD Audio Manager with the ATI HMDI default Audio device.  All records are up-to-date.

When I put my TV off and leave the computer running, I go back and turn on the TV and the computer behaves as the TV is not plugged, but only for audio.  The video is still there.  In the audio playback window, I noticed that Windows would go to the optical audio device, even though there is nothing plugged into this Jack.  I disabled all other devices and left only the HDMI device, so it will not move on.  Now when I turn on the TV it is just like nothing is plugged in at all for the audio.
Any help is greatly appreciated!

Hello
 
1. What is the brand and model of your computer?
 
2. which edition of Windows are you running?
 
Example: Windows 7 Professional 32 bit.
 
It could also be a possibility that a manual entry is required from your TV to the HDMI connection, please check your Menu\setting where the HDMI and PC connection is checked once it is connected to options to switch the Audio and TV screens.
 
Please follow the steps mentioned below to help solve the problem.
 
To disable improvements audio speaker

 
a. open sound by clicking on the Start button, then Control Panel. In the search box, type soundand then click on sound.
 
b. on the playback tab, click speakers, and then click Properties.
 
c. click the enhancements tab and then select the check box turn off all the improvements .
 
If you do not see the enhancements tab in the speakers Properties dialog box, these features are not available for your speakers, and this procedure is not applicable to your computer.
 
If disabling audio enhancements solves the audio problem you are having, this indicates usually that your audio driver needs to be updated.

Reference:- why don't I hear audio when I connect my computer to a HDTV?
 
 
I hope this helps.

  • Why am I suddenly "USB not recognized, one of the devices USB has malfunctioned and Windows does not recognize"

    Hi all. If anyone out there in Cyber Land can solve this problem for me so I've personally you will issue an eight-pack of ice-cold beer (or a bottle of wine for the ladies lol)...

    I'll try not to waffle too guys, so here's...

    Right my PC running Windows XP. I also have itunes installed on my PC (I have an iphone 4). Upward until yesterday my iphone and itunes were working well, (once I plugged my iphone in the itunes USB port recognised that my iphone was plugged and synchronization was fine etc.).

    But now when I plug my iphone to PC to sync with itunes, I get a pop up box on the lower right part of the screen that reads... "USB not recognized one of the USB devices has malfunctioned, and Windows does not recognize."

    After visiting about 5 different sites now "Ways to solve this problem", believe it or not, I still have the problem bloody! :(

    A site proposed shutdown PC and unplug it from the power supply, then plug it back start-up and back... this as did not work!
    The other they say that I should go to Device Manager, uninstall all the USBs then restart... it did not work either.
    Tried a system restore
    Tried to reinstall itunes

    When I check the names USB in Device Manager, there is one who reads unknown device. I am literally pulling what's left of my hair now. I tried to solve this problem for almost 2 days now and still no joy. That's why no matter what input you guys would be very appreciated. I'm no PC Wizard, so please, don't think you're patronizing me if you break down things step by step for me.

    Thank you comrades, cordially, Freddy frustrated. :)

    Another said I should go to Device Manager, uninstall all the USBs and restart.

    Usually, this works... but can be very dangerous, unless you have a PS/2 keyboard.

    I also assume that you have tried all other USB ports on the computer. tried a verified USB device (for example, a flash drive) in the USB usually when you plug in your iPhone. and I tried your iPhone in another computer (I know it's rare for an error message Windows really means what he says, but sometimes the material lacks).

    Is the charge of the iPhone when it is connected to the USB port (I don't think)?  This happened to me recently, but a reboot fixed it.  I guess that that happened to you.

    I guess that you don't see the error messages in Device Manager or you must declare them.

    You can uninstall all USB devices that do not exist as follows:

    • Open a command prompt window (start > run > cmd > OK)
    • Enter the following command and press enter

    Set devmgr_show_nonpresent_devices = 1

    • Start the Device Manager by typing the following in the same command prompt window

    devmgmt.msc

    • In Device Manager, click the view menu and select "Show hidden devices".
    • You should see a category just after "Non-Plug and Play drivers" named "other devices."  Chances are that there will be a big exclamation yellow mark beside it.  When you expand the "other devices" you should see several non identified "USB devices."  Uninstall all this.
    • Reboot (with the iPhone NOT connected).

    His salvation,

    Thanks for posting your query in Microsoft Community Forum.

    1. What are the troubleshooting steps you have tried so far?
    2. If it works much earlier? If so, did you do changes on the computer before this problem?
    3. What type of USB device you are using?

    As you mentioned that the USB device does not work when plugged into a WinXP machine, it may be a problem with the device itself. In addition, the question may also arise if the currently loaded USB driver has become unstable or damaged or if your PC requires an update for problems that could conflict with a device USB and Windows.

    Therefore, I suggest you try the following methods (skip the ones that you already tried) and check if the problem persists.

    Method 1:

    Please try the fixit (s) provided below which will help you solve common problems associated with devices and USB ports.

    If method 1 does not work, try Method 2.

    Method 2:

    Remove and reinstall all USB controllers.

    1. Open Manager devices by clicking the Start button, click Control Panel, click system and security, and then, under System, clicking Device Manager. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
    2. In the list of the categories of equipment, locate and expand Bus USB controllers.
    3. Right-click every device under the Bus USB controllers node and then click Uninstall to remove them one at a time.
    4. Restart the computer and let the USB controllers get reinstalled.
    5. Plug in the removable USB device and test to make sure that the problem is solved.

    If the problem persists, go to method 3.

    Method 3:

    This method will install the latest drivers from device to your USB device.

    1. Click the Start button, type Windows Update in the search box, and then click Windows Update in the results pane.
    2. Click find updates. When the scan finished, click optional review updates.
    3. Click the check box next to the update, and then click install updates.
    4. If you are prompted, read the license agreement, then click I agree.
    5. Follow the instructions on the screen to download and install updates.
    6. If you are prompted, restart your computer.

    Hello

    I'm having a problem with a PSAA5A-01H00T A100 running Win XP sp2.
    Windows does not recognize an ethernet controller, so the wireless NETWORK card does not work, even if the wired connection is.
    I tried to install the latest WLAN drivers on the support site (two of them), does not. Windows insists that the correct drivers are not installed.

    I suspect a hardware problem and I have the user on an external wireless NETWORK card, but I would appreciate any idea that you guys can provide.

    Thank you.

    Hi mate

    What Ethernet controller is not recognized? WLan or LAN?
    You have a few unknown devices in Device Manager?
    If so, then a critical driver is missing, and so the controller is not recognized correctly.

    You n t know what LAN or Wlan chip you have and what driver is needed?
