    Unable to get sound when you import video clips (.m2ts) Cannon for Windows Live Movie Maker video recorder or on the video file (.wmv).  Does anyone have a suggestion as to how this can be done?

    Hi RichGraff,

    • You have sounds in the VCR of Canon?
    • Are you facing problem with this video or other videos as well?

    For now, I suggest to import the video clip in Windows Movie Maker, which is an application integrated into Windows Vista and check if you get its in.

  • iTunes is not able to find the USB controller on PC desktop computer and laptop

    Hello

    Since the two versions of iTunes for Windows (10) diagnostic program tells me a green dot in front of "USB-connections", but didn't tell behind the "no-USB controllers found. That's why my iTunes is not able to connect to the iPhone 5. I have the same problem on my desktop and on my laptop. Windows detects all my USB Ports, well. If someone can solve it? Thank you.

    If your iOS device does not appear in iTunes, try the following:

    1. Open Control Panel > Device Manager
    2. Plug in your device
    3. Locate Bus USB Controllers > Apple Mobile Device USB Driver.
      It is also possible that the device may appear under imaging devices, portable devices or other devices or as a device USB of MTB.
    4. Right-click and select software update of the driver...
    5. Click Browse my computer for driver software
    6. Go to C:\Program Files\Common Apple Mobile Device Support\Drivers or
      C:\Program Files (x 86) \Common Files\Apple\Mobile Device Support\Drivers
    7. Click on let me pick from a list of drivers for devices on my computer
    8. Click on Apple Mobile Device USB Driver
    9. Click Next, then close and exit the Device Manager

    To step 3 above, open the Device Manager. Expand one of the articles that are listed.

    • USB Bus controllers
    • Imaging devices
    • Portable devices
    • Other devices

    Plug in the appliance. You should hear the telltale Windows sound device connection and a Division must acquire a new entry. This should be your device. It cannot be labelled properly at this point. If you do not hear a suspicious noise cable damaged.

    Or try If iTunes does not your iPad, iPhone or iPod - Apple Support Apple version of the above opinion.

    If not try a complete tear down and rebuild iTunes in accordance with the resolution of the problems with iTunes for Windows updates. 64-bit users might also try the build replacing iTunes for Windows (64-bit-for older video cards) which is sometimes a useful workaround.

    Or try to go back to the last version of iTunes that has worked for you. See the programs installation of iTunes to download links. If you roll back to 12.4.0.119 to 12.3.3.17 or 12.3.2.35, for example, then you will also need restore the database of the library in the manner described in the empty/corrupted after upgrade/crash iTunes library. The tip makes suggestions to reintroduce recent purchases, so at worst, you lose a few meters or a newly created playlist.

  • Not able to install the common module on satellite Pro A120

    Hi guys:
    I recently reinstalled xp professional on my satellite pro A120. I could download and install the main drivers of http://uk.computers.toshiba-europe.com and my phone is functional. However, I did not all sounds and (F6 & F7 and toggle) function keys not working, even after insalling the sound card. I read some of the posts on this forum and found that I needed insall the 'common' module to make them functional. I downloaded the driver from module common too, but when I run the Setup it starts initially, but fails both the configuration is complete.

    The same thing happens also with a few other drivers as saver of energy etc... I was not able to run the Setup program for the common module & driver power saver, basically, nothing happens after I have the respective installation.

    Can anyone help please?

    Pravesh

    As far as I know on the download page you can find the installation instructions with exact installation document order how to install drivers and tools specific to Toshiba and utilities.
    You have installed all the stuff after this installation order?

  • Tecra A3 - 152 - not able to read CD - R (or CD - RW), burned by itself or another PC

    Hello

    My TECRA A3-152 offers the CARPET * a DVD-RAM UJ - 831S player (1.40 firmware version) with the Microsoft (dated the 1.07.2001) 5.1.2535.0 driver
    The laptop is not able to read the CD - R or CD - RW engraved with any other PC (or alone). The CD is reported as empty.

    However, the reader is able to read commercial CD - R with SW or sounds or other stuff.
    After several hypotheses about the SW problems or compatibility issues, I intend to replace the drive with another.

    Any suggestion?

    Thanks - regards
    Antonio Giarrusso

    Hello

    Maybe it s only a problem of compatibility. In my experience not on each CD or DVD is compatible. I mean that not every CD manufacturing is supported by the firmware and so this question might appear.

    But let's try some common tips.
    First of all, I would recommend delete Sonic record now and the DLA.
    Then restart the computer and enter the registry.

    1. in the registry editor, expand my computer, and then expand HKEY_LOCAL_MACHINE.
    2. expand SYSTEM, and then expand CurrentControlSet.
    3. expand Control and class.
    4. under category, click on {4D36E965-E325-11CE-BFC1-08002BE10318}.
    5. in the right pane (topic area), click UpperFilters and delete. Click then click LowerFilters and delete is also.
    6. click on Yes to confirm the deletion.

    After this procedure, restart the laptop and try to read the CD

    Hello

    Thanks for posting in the HP Support forum. Welcome!

    I'm sorry for the problems you have. I'm afraid that beeps usually indicate the sound of the motherboard and is not a good sign - usually some sort of hardware failure or problem.

    What do you say "he's not leaving"? He kept playing with his only non-stop?
    If it is 'yes' or 'no', you can always he kill 'soft' media player.

    Take a look at your video accessory. What are the last 3 numbers, such as avi, mpeg, mov etc. ?
    It is possible that your video accessory is in a format unsupported by Windows Media Player.
    Save it in a folder of your choice.
    Googe for a FREE video converter (if you do not have one) and convert the video file toWMV.
    Now you should be able to read in the drive media with images and sounds.

  • Not restart and not able to install vista, cutting frequently

    My computer toshiba laptop satellite cutting frequently, I thought that it is a virus problem and tried to format and install vista again several times, but is not able to restart, when you restart turn off until windows appearing, is this a problem of viruses or of any material DEFECTS, I also noticed that becomes fire, we feel it when press on the button can anyone give me a solution?

    It sounds like you are not booting from the disc but on the hard drive.  To access the options of environmental recovery and the installation option (this is a clean install, made that way you will lose everything on your hard drive, including your data), you will need to boot the disk.  You may need to change the BIOS to do first the CD drive in the boot sequence to boot from the CD.  To do this, hold the screen that tells you the key F to push to enter the menu start or start of installation.  Push it quickly. Make the changes, save your work and exit.  Put the CD in the drive and reboot.  When you are prompted, press any key to boot from the CD.  You're not actually getting Windows - it will not appear until the drive is running.

    I hope this helps.  If you would help as trying to fix the problem instead of simply to do a clean install, all you need to do is ask.

    BTW, you can use Knoppix http://www.knopper.net/knoppix/index-en.html with a good ISO as Copier: http://isorecorder.alexfeinman.com/isorecorder.htm as well as a blank CD.  Boot the disk.  This should give you enough access to the system (if you do not have any other means) to backup your important data (if you have a place to put it).

    Good luck!
