my sound disappeared

The sound worked a few hours ago, and then he disappeared. At the same time I noticed that songs downloaded on Itunes in my record player stopped loading. I have no sound at all here - not even on shut down/reboot. I also noticed this application called wbengine.exe was using all CPUS & my lap top warmed alarmingly. According to Norton 360, it is not harmful...

Any help is appreciated. Thank you!

  • When a clip is cut, the sound disappears. What should I do?

    Hello

    I do a video with Windows Movie Maker and I added some clips to it. I cut some of them, but the problem is when I prune, the sound disappears. What should I do to fix this?

    Instead of prune... try to split the clip and
    remove the unwanted chronology part.

    Also... If you drag a copy of the video clip to the
    Audio / music... He's going to react like any other audio device
    clip. Maybe you can use it and cut video

  • Computer HP Pavilion laptop g6 sound disappears.

    Hello

    I have a problem with my laptop. When I feed my camera everything is fine, but then... we go several minutes sound disappears. The strange thing is that "mute button" on my keyboard does not respond too, when I hit him theres no light orange and the other the screen appears a lvl of volume (normally, it should be a cross-volume lvl). When I want to play Spotify or something like that, he said that my sound card is being used by another program... The funny thing is that when I did something like 'stress test' (I played Spotify when its worked just after the system startup) sound worked for about 6 hours and everything was fine. I hope that I will find any type of need here.

    System: Windows 8

    Model: HP Pavilion g6-2310sw laptop

    Also, I want to add that each system reboot solves this problem but only for a period of time (several minutes).

  • HP Pavilion Touchsmart kept Sound disappears after installation and reinstalling the drivers

    I have a HP Pavilion Touchsmart 14-B132TX Sleekbook. My sound disappeared while I was using it a month ago. I called the HP Hotline and Technical Support told me just uninstall it from the Device Manager and when restarted, automatically installs the driver. What I did.

    The sound came back but still once he disappeared after about 15 minutes of use, so I called tech support again and they gave me links to HP support for drivers to download and install which I did and rebooted the computer and the sound came back again. BUT again, the noise has disappeared. I called tech support and they just do a system restore which I did and the sound came back again. But he disappeared again after all just 7 minutes of use.

    These are the drivers, I installed from the HP Web site: sp60642, sp64082, sp60464 and sp64031. After reinstalling the drivers. I cleaned my laptop with CCleaner and went to HP Support Assistant in the hope of getting a solution, there was a statement here to download the QUALCOMM Atheros driver and I installed again the driver said... The sound has come back after rebooting. AND again, he has disappeared after just using the laptop for about 3 minutes. (it gets worse!.) This laptop is quite new, he just bought 10 months ago. What is going on? Please help me. I use the Windows 8 operating system. PLEASE HELP ME.

  • After having saved HP, all the sounds disappeared

    It asked me to update my Bios (?)  A few weeks ago. Yes, I did. Later, I noticed the laptop was strangely like the internet would be cut frequently. I went to save the laptop for a moment before the problem happened. Bandwidth works fine now, but all the sounds disappeared. I checked for problems using 'Help' suggestions, but he tells me that everything is fine. The sound is output from the headphones or the internal speakers.

    Can I have supported it until before the Bios (?) has been updated.

    The laptop is a HP Pavillion (about 2 years) using windows 7 and Norton 360 (which I ran scans to try to find a problem as well)
    Any suggestions?

    Thanks much for the reply. The model would have helped! haha. (it's a HP Pavilion)

    After that I wrote here, I checked a few other places and saw a post that said to uninstall audio driver and download a new one. It worked.

    Hello

    Thanks for posting the query on the Microsoft Community Forums.

    It seems that the audio does not work properly and must be repaired. We will analyze and identify the cause of the problem.

    What is the brand and model of the computer?

    This problem normally occurs when the audio driver is damaged. We will run the audio Troubleshooter and update the drivers to the latest.

  • Satellite C660/C850 - sounds disappears - then returns

    Just a quick call to see if anyone has encountered something similar! :)

    A bit of history... I work in a secondary school.
    We currently have 50 laptops Toshiba C850 and 20 notebooks of Toshiba C660, although these totals, only 30 are allocated to members of the staff.

    We had some staff members say the sound suddenly disappears on their laptop.
    A teacher can play a clip on YouTube, DVD, or a presentation, and the sound suddenly stops working.

    This affects the internal and all connected speakers speakers.
    A teacher said that this anomaly occurs approximately 1 to 2 times a day, without exception.

    I had a quick glance this morning and of course, a YouTube clip was playing, but not sound.
    All the usual volume controls were nice and high.
    I tried to play one of the default Windows system sounds and you could hear it!
    I tried to play the video for YT, once again and nothing.

    As soon as I reloaded the page, the sound in the video for YT worked.
    However, according to the Professor, if he clicks on the control of volume and moves the cursor to create this famous "beep", it does not normally... and I think.

    All laptops are on Windows 7 Pro, and run the drivers from the Support from Toshiba site.
    I'll try to install the new chipset and audio drivers following, but thought I'd throw it out there to see if anyone else has experienced similar... and fixed it?

    See you soon! :)

    > I had a quick glance this morning and of course, a YouTube clip was playing, but not sound.
    This happened to me also using a unit of Tecra A11.
    The Youtube video had no sound, but if I plugged and re plugged the headphones, the sound appeared again.

    I thought that it was a problem with the headphone jack but I wanted to check if this problem could be solved by reinstalling the driver.

    First of all, I uninstalled the audio driver Realtek system. Then I went into Device Manager and deleted the high definition Audio Controller in the area of system devices.
    In Audio, video controller and games, I've removed the Intel audio input displays.
    Finally, I rebooted the system.

    After restarting again recognized windows devices removed. I have checked the Read tab in the control panel-> sound and found new headphones to the device that was not visible before.

    Then I started Youtube and checked the sound. She was available. Then, I installed the latest version of the Realtek HD audio driver and restarted the machine.
    The noise was still there

    So hopefully it was just and issue of pilot
