Sparks (noise) on video playback

Just noticed this - probably began sometime in the last few weeks - video playback is quite 'noisy '.

The same files play fine on other machines.

Has anyone else noticed this lately?

Ah... seem to have difficulty - in fact one of these Nvram resets...

(off tension, restarted - then at the start-up tone, until a second start-up sound hold cmd-opt-P-R)

  • I have a thumping sound during video playback.

    I have a computer Dell Inspiron 1545, 64-bit laptop, equipped with Windows 7 family Premium SP1. During video playback, streaming online or a video on my computer, I get a noise very loud from time to time. It is almost an audio feedback effect. Sometimes the video hangs at the noise. I've updated the audio drivers; I deleted the audio driver in the Device Manager and rebooted I tried another card sound and different speakers. Nothing works; I always get the noise and the occational of freezing. I read a lot of articles online from other Windows 7 users, indicating the same problems, so I have to believe that this is a problem with Windows 7 itself. If you go on Bing and just type in Windows 7, this site and others coming, talking about sound and freezing problems. What is the problem with Windows 7 and what is Microsoft going to do to correct the problem? I often have to connect my laptop to my TV for playback of movies, but the noise is very discouraging. Help!

  • iOS 10 video playback stops working until you restart

    I have an iPad Mini retina, and since the upgrade to iOS 10.0.01, a short period of use causes videos to stop working.

    Videos in Safari, Chrome, YouTube etc. appear in the cache (saturated with progress on the top bar), but no response to play. The first image of a video appears, but only in the form of static image. I am able to change the static image displayed by rubbing them at any point in the video, but playback will not occur.

    The only thing that allows video playback is again restart the device (apps force closing, locking and unlocking etc. doesn't help).

    Hello, Sunkai!

    Thank you for using communities Support from Apple. I understand from your post that you're having trouble playing videos on your iPad mini; the video will start but will be stuck as a single image, as if the buffering and never take back (at least until you restart). I mainly use my iPad for watching videos, so I know it's important that they play in fact; I'm happy to help you!

    I have some troubleshooting I can offer to you. Before you begin, create a backup of your iPad using iCloud or iTunes, following the instructions here: How to back up your iPad, iPhone or iPod touch

    Once you have your backup, try the following steps, in order. A video test after each step and will stop when the problem is resolved.

    1. Make sure your iOS software is up-to-date. In the last week, iOS 10.0.2 came out. Use the following article to get help update: update the iOS on iPhone, iPad, or iPod touch software
    2. If this happens on a Wi - Fi connection, try restarting the network you are using from the router or the modem (if possible). If it is a private (for example, your home network) WiFi network, try to remove all the devices on the network, then by simply adding your iPad in return.
    3. Try a different network.
    4. Reset the network settings on your iPad under settings > general > reset > reset network settings. This will affect all personal data (like your photos, contacts, calendar of events, etc.) but it will remove saved passwords, and Wi - Fi networks one previously used settings APN or VPN and all paired Bluetooth device.
    5. Restore your iPad settings, following the steps described here: use iTunes on your Mac or PC to restore the iPhone, iPad, or iPod touch to factory settings

      Once the restore is complete, configure the iPad as a new device (i.e. without using the backup that you created earlier, at least temporarily). You can sign in iCloud, iTunes and App Store, iMessage and FaceTime with your Apple ID test then a video.

      If the problem is resolved, you can restore your backup by the information here: restore your iPhone, iPad or iPod touch from a backup

    Have a great day!

  • Flash crashing and video playback/Streaming problems

    Recently did a reinstall of Windows 7 and have experienced problems with Flash and video playback in general. Questions may or may not be related. I have not detected problems with the opera and so I think that these are problems of Firefox. 3 major video sites that I use are (HTML 5 player) YouTube, twitch.tvand Crunchyroll.

    (1) flash very quickly and systematically accidents

       * Specifically noted when viewing streams on twitch.tv
       * Often crashes within a minute, almost certainly within a few minutes
       * Crash logs provided below
    

    (2) reading crashes

       * Occurs on all 3 sites
       * On twitch, stream freezes (but Flash does not crash). On YouTube, loading circle comes up and video freezes
       * If this occurs on twitch, Flash less likely to officially crash
    

    (3) volume cuts

       * Occurs on all 3 sites
       * If this occurs on twitch, Flash may still crash after
       * I've had volume issues with my system in general, with volume occasionally cutting in gaming programs, such as League of   Legends and Hearthstone. That being said, I do not experience this issue with Opera and this only occurs on video playback in Firefox.
    

    Flash Crash IDs:
    BP-8e2f650d-7fc2-4235-a864-ef4282151205
    BP-a6760c7c-c561-4be5-BD48-bea1f2151205

    BP-2cee7e29-008C-4e6f-9FAA-eea992151117

    Attempts at Solutions:

       * Disabled hardware acceleration in Flash
       * Reinstalled/Updated Flash and (I think) made sure there is only one version of Flash
       * Reinstalled/Updated Firefox
       * Cleared cookies/cache/other stored web data
       * Updated all drivers
    

    I wouldn't stop using Firefox as my preferred browser and works fine on all my other devices, but if the problem persists, I'll have to. Any help or insight is appreciated!

    Unfortunately, I have tried all fixes of cor - el without success.

    However, I started to use audio drivers Realtek instead of Microsoft and everything seems to work more smooth. Will update later when I did several tests.

  • Video playback stopped working in Firefox until I DISABLED the plugin of primetime content decryption module

    From one day to the next video (youtube, Vimeo, etc) stopped not working in Firefox. I checked my plugins/addons and discovered the plugin Adobe "primetime content decryption module" which I had not noticed previously had been installed. I've disabled the plugin and found that the video playback was still functional.

    I realize the Primetime plugin is intended to facilitate playback of certain content (DRM), which would not otherwise play with Silverlight/Flash plugins, but unless that I turn it off it's actually prevents me from normal video content playback.

    As this is a Firefox/Adobe plugin suggested I prefer it to work as expected rather than disable/remove it.

    A quick update to my problem noted above (maybe I should try this first)

    I ACTIVATED the plugin once more see if it would cause video playback yet, but everything seems to be ok now (IE, Primetime plugin is activated and all videos play normally)

    Will report if the problem arises again

  • Re: Satellite L650-165 - blue screen during the video playback or games

    Hello

    In October, I bought my L650-165. However, since then, I was faced with the blue screen of death. This happens when either video playback, streaming video or play Football Manager 2011 (video game).

    I think that my problems are all the graphics card related. However, I am really at a loss. I've always used Tosh laptop computers but this problem starts to grate. I keep coming back to my trusty 5 years Equium!

    I'm not that great with Windows 7, so I would appreciate any pointers or possible solutions.

    Everything works fine but the video playback in full screen - no matter, I use the flash player, VLC or WMP. Video playback works well in window mode, but when I switch to full screen, just a black screen and the cursor of the mouse appears.

    Interestingly, when I press the right mouse button to open the context menu all in video playbyck, video is shown both that the context menu has the focus.

    I've updated to the latest display drivers, but it did not help.
    Does anybody know a solution for this?

    Thank you

  • Z500 Touch is slow video playback of the external HARD disk

    Hello

    I knew video slow reading (more than a minute) drive external HARD on my Lenovo Z500 touch. I used different actors updated (vlc, windows media, Media Player Classic player) who gave the same problem. I have no video experience slow game with multimedia files on the HARD drive inside (less than 15 seconds).

    So, what happens? USB problem?

    Hi ColonelONeill,

    I try to boot my laptop with the power profile high performance. I was surprised to discover that the problem of the slow video playback of the external HARD drive has been resolved. When I double click on the multimedia file, it took my laptop less than 8 seconds to play. So, I does not work using HD tune benchmark.

  • Satellite L305-S5921 - video playback is fuzzy, not clear

    I hope this isn't a double wire - I have done several searches, but couldn't find it, so forgive me if I missed it.

    In any case, I bought the L305-S5921 a couple of months. It's a great phone for the price. My only complaint is video playback - it is not at all crispy and is rather blurry. When I watch DVDs and watch videos of resolution "superiors" on Hulu, it's blurry (Note: 'High resolution' Hulu is 480 p).

    I tried to adjust the resolution of the laptop before video playback, but it doesn't seem to help.

    I read a review of this laptop on the review of a store page, and he said he had to change video playback. Someone has any idea how to "fix" it? I couldn't email this person, as it was anonymous.

    Or, do you know if any programs (like ffdshow) will help? I think this can help with the DVD, but does anyone know if it would help with streaming from Hulu?

    If you can help, please be as explicit as possible - I have some technical knowledge, but this problem seems to be beyond my comprehension!

    PS - everything on this laptop looks great - photos, games I play (not too demanding of salvation graphics, etc...). It's weird because I've had this laptop to replace your old desktop (7 or 8 years old) that I had (with a CRT monitor). But, this monitor seemed better on video than this laptop brand new with a resolution of more than world!

    Thanks in advance!

    Hello

    Especially videos that are broadcast from different pages are saved or transformed in low resolution.
    Why?
    Due to the transfer of data high.
    Movie files high resolution are too large to download common or upload.

    So if you scale movies in full screen, then it might be possible that the resolution of the film would not be perfect.

    But this isn't a number of laptop but it s files of movies that are broadcast from different pages like youtube or hulu

  • video playback iTunes 12.3.1.23 does not

    I tried iTunes closing and restarting the computer.

    I also tried to change my preference of video playback 720 p 1080 p, as suggested in another thread.
