Speakers cut out after 1 or 2 minutes on my Satellite L750

The internal speakers on my Satellite L750 - 16Z (PSK1WE) cut off after 1 or 2 minutes when playing any track video or music. The headphones work fine. The sound can be restored by plug it and unplug the headphones. The speakers work again with the new application, or after a long pause, then they cut. It happened that the computer is new, only after about 18 months.

I've seen dozens of posts on forums US of people who have this problem. I am running Windows 7 64 bit, but I see that people have the same problem with Windows 8. I have tried most of the proposed solutions:

Reinstall the audio driver (in my case Conexant Smart Audio HD version 8.51.1.0);
Closure, by removing the battery, etc.;
Alternatively clicking on playback and recording in the settings dialog of the sound;

and * none of them recherche.* I'm not willing to do a system restore and the risk of losing my data. With the help of external speakers is not a solution for people who travel (would not have bought a laptop if I had to carry a suitcase full of accessories to make it work).

I should really grateful for the help on this

I got exactly the same problem with my laptop. But my laptop supports the Realtek HD audio driver.
However, the same problem occurred. By speakers disappeared but the helmet worked.

I m sure its software related issue. From my point of view of a few you would be able to resolve this problem by installing the new system, but it would be a very drastic just to get rid of this annoying problem procedure. I was able to solve this suite of this workaround.

In Device Manager, expand the Audio category video game controllers
Look here for the Audio device high definition and delete

Expand System devices and look for high definition Audio Controller
Mark and remove it.
Also you could uninstall the audio driver Conexant. But in my case, it was not necessary.

After that, restart the laptop and wait for that deleted devices has been recognized and installed again...

Good luck

  • Connecting the projector cuts out after 10 minutes

    Hello

    I scoured internet help forums looking for answers, and nobody seems to have the same problem I encounter. Here goes:

    Details

    Laptop - Lenovo IdeaPad N585

    OS - Windows 7 Home Premium

    Projector - Samsung LCD TV series 5

    Connection - cable PC monitor

    The thing Flash = times computer laptop and TV simultaneously Flash back and forth between a black screen and the desktop, making the connection/disconnection of the sound device with every Flash.

    My laptop connects to a projector (TV), but only momentarily, then he "cut" and made of flash. It can last for 10 minutes or 2, coherence time is hard to follow and I can't understand the reason why he cut... It's never more than 10 minutes.

    The order is that I connect issues. If I connect the cable to the two devices before (windows + P) connect to a projector, then it will automatically do the flash thing. But if I have (windows + P) connect to the projector (duplicate, expand does not matter) before connecting the cable, then it runs for 10 minutes. I tried different power configurations portable vs TV first and vice versa.

    I updated my drivers (I think) through automatic updates of Windows... If it helps, I don't see TV as a device when it is connected.

    He works now :)

    I went to a HDMI cable and it works fine (even easier in fact). Does not my monitor cable connection problems, but who cares at this point? Hope that if anyone is in need of an answer to the question even will be able to switch to HDMI as well.

    See you soon

  • T410s internal speakers fade out after a second, headphones work fine

    Hello community,

    My THinkpad T410, type 2912-45 G, Windows 7 (64-bit) has a problem with the speakers.

    From Monday (June 25) my speakers stop working. When I boot the TP you can hear a static click through the speakers, and he plays the sound windows for a second only. After the second, you hear another click static and speaker no longer works. It's just fine with all other audio content, when the TP is initialized.

    After pressing the Mute button, or volume-to top keys or to low volume speakers return to work for a second about (always click static, just before this second and thereafter).

    When I plug my Headpones, everything works fine. When I unplug my headphones, speakers work again for a second.

    I already updated my BIOS, installed and uninstalled the driver, active the card its (CONEXANT HD AUDIO 20585), tried to update the driver. But nothing has worked so far. I already checked if the switch in the headphone jack is stuck, but I couldn't find anything.

    Did anyone experience the same or a similar problem? As the speakers for the second city I suppose, that the material should be good. As the headphones work correctly the sound card must be detected and properly mounted.

    I would appreciate if someone could help me with that. Sending the TP (it's always guaranteed whitin) will be my last option because I need TP to work.

    Thank you very much.

    Hi thecez,

    Sorry to say this, but it seems hardware problem. Please try BIOS and driver both power management. If the problem remains, please contact local lenovo when your machine is available for inspection.

  • USB speaker cuts out / gels

    Hello

    I have USB speakers connected to my laptop. When I play music with media players (tried a bit with the same question) the speakers cut out (actually its almost like if he freezes; the media player progress bar and volume bar indicator seem stuck and the sound cuts). I need to unplug and then plug the rear speakers to make it work again. This occurs anywhere between every 2 to 10 minutes. Very annoying.
    The speakers work very well in other situations. I can read videos, films, etc. on media players without question. Sometimes during the streaming media, but not as often.
    Have the latest drivers etc. Have sought long and seriously of similar issues on the internet, but have not found a single person with this problem.
    Any ideas?
    Thanks for any help.

    Hi dazzler902,

    What is the file format of the audio files that you try to play? This happens with all audio files or just with a few specific files (file format)?

    To refine the question, I suggest you try the following steps:

    Step 1: Try to play audio files with a different drive

    If the problem persists, the audio files may be corrupt or damaged.

    Step 2: Run the Fixit available in the link below

    http://Windows.Microsoft.com/en-us/Windows-Vista/tips-for-fixing-common-sound-problems

    Step 3: If the problem affects all or most of the files you play (as opposed to a few specific files), the software of the driver for your sound card (also known as an audio controller or audio device) might be obsolete. You can check the updates by following these steps.

    1. open Windows Update by clicking the Start button, all programs and then click Windows Update.

    2. in the left pane, click search for updates, and then wait while Windows searches the latest updates for your computer.

    3. If updates are found, click install updates.  If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

    In some cases, you may need to download the driver software directly from the Web to your computer manufacturer or the manufacturer of the sound card.

    Since the installation of El Capitan, my streaming to my Audioengine DAC D2 cut after 12 minutes (the default duration of sleep). It will restart by pressing the space bar. When I change the duration of sleep, the cut outs are becoming more frequent and intermittent. Help?

    I checked the wifi and changed frequency (new modem, frequency change made no difference). The Board battery seems fine - all updates well. My computer is an iMac (2011), 3.1 GHz Intel Core i5, 8 GB 1333 MHz DDR3, with a new AMD Radeon graphics card. I recently installed a State strong 1 TB SATA drive and fitted with a LaCie Porsche 4 to USB for backup and a 4TB disk storage RAID LaCie drive.

    I'm frustrated, having to come in my computer since my living room every 12 minutes to continue to listen to Spotify on my stereo system.

    My guess is there a bug in the software of sleep in El Capitan, which disrupts his (I've tried different USB ports connect the Audioengine sender and same thing).

    Should I go back to Yosemite?

  • Satellite Pro A60 cuts off after 3 minutes

    Hello

    work in IT Support generates many puzzles, but I currently have a Satellite Pro A60 which cuts off after 3 minutes.
    I have deleted the main CPU fan and have noticed that the VGA Chip Set fan fails.

    It is not at all which makes me think that it is completely broken or there is a problem with the motherboard.
    Who is more likely and if not card mother, can I buy a VGA heatsink thermal elemnet / separate fan and if so what is the part number and ball park cost?

    Matthew

    Hello

    As you already suggested this strange faucet portable bottom may be related to high temperature and to overheating.
    You are right; the malfunction of the fan could be a reason to close automatically and sometimes down.

    > can I buy a VGA heatsink thermal elemnet / separate fan

    Usually, the cooling modules are pieces separately and can be replaced.
    But notebooks disassemble and replacement of cooling modules is not easy and a little more difficult for someone who has no experience and never changed something like that. It s just too risky, because this person may damage the motherboard very easily.

    So, it's probably best to contact the technician of specifications for these s replacements!
    The ASP can command the support of the head of Toshiba warehouse cooling modules and compatible and could replace it.

    Best wishes & congratulations buddy ;)

  • Cut out the background, brighten the image and the image speed

    Hello world

    I'm sure it's a very simple answer, but I'm new to photoshop and have searched for a solution to this problem for a while. There seems to be so many different ways to approach it, I thought that I would ask you guys what you think and get a specific answer to my problem.

    ------------------------------------------------------------------------------

    I took a picture of my products with a good camera located on the highest image quality in a lightbox. I then want to take this picture and cut out the background (make white) and brighten the image of the products themselves. This image is then used on our posters, banners, floor stands, brochures... Made on a range of promo material and, above all, to a range of different sizes.

    I took the image in photoshop and used the tool to select around the edges, then used "curves" and another adjustment (I forget which) to make the space around the white image. Then I inverted the selection and used the same settings to make the image itself slightly brighter.

    I sent it to a printer, and they said that because I had used this process, the background I made white may not be the right shade of white printing and appear as a different shade, a box around the product on the banner (although I printed on my printer at home and I can't notice a different shade). They also said that my image was not clear enough, and he had to be 300 DPI instead of the 72 dpi that my camera took the picture. (I posted about this problem of IPR before and got useful answers, but now I'm starting the process of zero thought I would mention it again)

    I have attached the original photo and also the picture after my editing on photoshop for reference. Both in low resolution.

    So to summarize, I need to get my products on background photos, brighten them up and make them 300 dpi then don't complain printers!

    Any help would be greatly appreciated. Thanks in advance.

    Kind regards

    Jamie

    Below: Shot Original camera file format original 72 dpi is 7MB

    IMG_2203LR.jpg

    Downstairs: shot after having been edited in photoshop. Although I have no more the .psd of this file. Only the .jpeg

    4Pack V2LR.jpg

    He had to be 300 DPI instead of the 72 dpi that my camera took the picture.

    The PPI (better word than IPR) makes no sense without the physical dimensions of print to go with it.

    You mention the different print sizes. Not all should be 300 PPI. (Large banners or posters may work properly at lower pixel density)

    Can you tell us one or two sizes of output?

    And, most importantly, tell us the Pixel size of the file? (Image > Image size > width and height in pixels)

    As I said in your other post, you have rhythm. But I need to know the target print size and the size of the file in pixels.

  • Problem of its satellite L750-1XK - work for 1-2 minutes then cuts

    I have a Toshiba Satellite L750 1XK, my laptop is about 18 months old now

    The problem I had is that the sound works for a minute or two and then cut! I saw a LOT of people in this forum have the same problem, but I'm yet to find a thread where the problem is actually solved.

    As with most of the people with the same problem, I can plug in headphones and remove them and it works again briefly, but then turns off again. I tried everything I can think of. I don't know much about laptops, but I tried to reinstall the drivers, I checked the Device Manager to see if there were problems in there, but everything seems fine.

    Then I thought that maybe my computer has too much stuff on it and, removed everything and defraged etc. and cleaned but still not working. So I decided to go a step away and actually restore laptop to factory settings, it all scratched and did install a clean windows and its still doing the same thing.

    I have really no idea what to do now. Is this a hardware problem, if so it will be an expensive solution?

    > As with most of the people with the same problem, I can plug in headphones and remove them and it works again briefly, but then cuts off again

    Had the same problem with my other laptop equipped with a card Realtek sound and I could solve this latest installation updated audio driver the Realtek driver page.

    But it seems that your Satellite L750-1XK does not support Realtek audio chip but the Conexant audio chip.
    Therefore, the solution could not be useful for you.

    However, I suppose that there are two possible reasons for this:
    (1) failure driver sound
    (2) failure of the sound chip.

    In case of malfunction of the audio driver, I recommend you to google for driver Conexant SmartAudio HD and test the latest version of the driver available. On the internet, I find the Conexant SmartAudio HD driver version 8.65.9.51 for Win 7 / 8 Win / Win 8.1

    To manually update your driver:

    1. go into the Device Manager (right click on my computer, choose manage and then find Device Manager in the left panel)
    2. right click on the device you want to update and choose Update driver software
    3. choose Select the location of the new driver manually and navigate to the folder where you downloaded the driver

    In case of malfunction of the sound chip, you can try to use an external USB sound card.
