Why no sound but video on tv

HElp

Just so you are aware, all HDMI cables are not created equal, their specs can vary wildly.  Call Apple and ask what the  proper specs should be.  I don't know myself, but one of my video friends told this info, you might want to check it out. I am an audio professional by trade, and am quite awar of cables having impact on performance.  Hope this at least points you in a direction, maybe someone on the forum can shed more light.  All the best

  • Audio sound but video still loading?

  • Music Videos - have sound but video does not play in windows 7

    I have windows 7 and the latest version of Itunes.
    Most everything seems to be working ok, but when i try to play a music video i get the sound ok, but the video never starts, it just seems to stay on the first screen shot and never changes, even when the next video starts.

    Not sure why, assume you got the 32-bit version if that is what you run, and this is quicktime? maybe you need a different codec or application for the movie format; or didn't associate the file type...
    but if it deals with iTunes you will find more help in iTunes Windows:

  • Why no sound on videos

    why do the videos on XF on my PC play but there is no sound?

    Thank you for that but please don't bother. It's embarrassing  to admit but I have solved the problem. My speakers were on but turned down to zero. Pathetic....Thanks anyway.

  • Flash Player has sound but video is a green screen.

    I am running Windows 7 x64 and did a new install on a new HD. No problem with my old HD installation.  I have an ATI XFX 6700 series video card, 8 GB computer RAM.  I have tried manual un-install per the youtube video.  I have deleted two Windows update files KB2735855 and KB2750841.  I installed the latest version of Flash Player 11.6.602 after reboot and the problem is in my primary browser Maxthon 3 and in IE9.  Both of these browsers work just fine for video, on my old HD. 
    I have re-installed the Maxthon browser as well.  Always a green screen in Flash video but the HTML video works ok.  The Adobe detector shows :
    This is after the sucessful update to 11.6.602.171  I also don't understand why it shows Chrome browser which I didn't have untill the Flash update snuck it in on the last download.  This showed Chrome even before that and I don't beleive Maxthon is a Chrome browser.  I have run out of options except to try a Window restore.  What can I do to get this fixed? Very frustrated.
    Other video card info:

    Pat, the video does work in Chrome.  But the Flash detector (1st picture) showed I was using Chrome before it was ever installed.  I think Adobe should at least recognize Maxthon browser and suggest the correct version of Flash.  
    I have the latest video driver and it was installed during my Windows install on the HD.  Perhaps it is a newer version than the one on my old drive, I will have to check.  I still have the green screen and I want to get video working in Maxthon which is a far better browser than anything esle I have tried.
    The Flash player in Chrome shows it is Adobe Flash 11.6.602.171, while the right clicking in the video player on Maxthon shows it is 11.5.502.110 so obviously Flash is not updating after I downloaded and ran the updater.  How can I get rid of this old version, I have tried the manual uninstall?  There must be some registry entries that are not being deleted.

  • Sound but video frozen when playing  .AVI and  .MP4 files

    I have several movie AVI movie files that cannot be played properly with Quicktime pro 7.4: the sound plays normally, but the video image remains frozen. These files play perfectly with VLC and Real Player. The identical problem happened with an iTunes movie rental. The problem persists after installing Perian, and re-installing Quicktime.
    Any recommendations about how to troubleshoot this?

    Here's what my Movie Inspector states.  What do I need to do to get Quick Time to show my video?  Audio is working fine.  Am I out of luck?
    If I remember correctly, "m2v1" identifies "muxed" MPEG-2 content which has been imported from a camcorder by any current/recent version of iMovie. Basically, it is an all I-frame version MPEG-2 video. (I.e., all P- and B-frames have been converted to I-frames to make the video QT edit compatible on systems with iMovie '07 thru iMovie '11 installed.)

  • Strange... No music sound but video sound works???

    I noticed this tonight while I was at work. I know its not the earphones cause it wouldn't work in my griffin roadtrip either. Only the video sound would. I am taking it back in the morning so hopefully Best Buy is good on their word. Has this happened to anyone else?

    I am having the same problem with my iphone sending airplay to apple tv it will send video it will even show up as apple tv being selectable in ipod and other programs. ipod on iphone even thinks apple tv is playing music because the timeline is moving. when i go and use airplay on my macbook pro all works fine video and music.

  • Though I have connected my receiver using thunderbolt cable/hdmi it does not emit sound, but i can see the display

    My imac does not detect the thunderbolt. so cannot select external speakers though I have connected the mac using thunderbolt to hdmi. cannot receive sound but video is seen.

    I have one thunderbolt port and one mini display port.
    No Mac has both Thunderbolt and Mini DisplayPort.  They are both Thunderbolt.  A Mini Disp;layPort cable or adapter will work in a Mini DisplayPort or Thunderbolt port.
    A Mini DisplayPort to HDMI cable or adapter can handle both audio and video, but some older ones are video only.
    You may have a broken audio wire in your cable.  Try a new cable or Mini DisplayPort to HDMI adapter.  Make sure it says it will handle both audio and video.

  • FCP through to External monitor....Sound fine but video is still frames

    Hi everybody
    In January of this year this problem was posted by Andy D.....
    +No matter what combination of settings I choose I cannot get video to play on my HD monitor only a still of the last frame shows up. When I hit play the audio is loud and clear and then when I hit stop the final frame appears on the screen.+
    I have this problem but only when the material in my FCP viewer, canvas or sequence is ProRes422 (I'd converted H264s to this before importing into project)! If the project is DV or H264 material that has been rendered by FCP, it plays on the external monitor fine but it seems if we start looking at the high end stuff like ProRes, back to sound but still picture.
    I might add here that the path to my external Full HD monitor is through firewire to an ADVC100 converter and then composite cables to the input of the monitor. By the way the same thing happens with an SD monitor.
    I haven't tried using my video camera as the link through to the monitor instead of the ADVC100. Would this make a difference? I'd be pretty happy if someone had a solution for this.
    Thanks in anticipation.

    Unless the camera is a DVCPRO HD camera...like the HPX-170...this won't work. Not via HDV or AVCHD. Playout isn't as simple as it was with DV. There are far cheaper capture cards...Decklink Intensity Pro, Matrox MXO2 mini...but you need a MacPro for those (or with the MXO2 MIni, a laptop with an Express34 slot). An iMac is severely limited in what it can do.
    Sorry.
    #25 HDV external Monitor Viewing
    Shane's Stock Answer #25 - HDV external Monitor Viewing
    To view HDV on an external monitor in high definition you are going to need to purchase a capture card, like the ones Decklink (www.decklink.com) or AJA (www.aja.com) offer. They will both play out HDV in real time. The catch is that you cannot view this on a regular TV or NTSC monitor. Since this is HD, an HD monitor will be needed. HOWEVER, both cards are capable of down converting the signal so that it can be displayed on an SD monitor. This won't be color accurate
    The real reason why you can't monitor HDV through a Firewire camera is because Firewire HDV cameras don't decode incoming HDV streams and route them to their outputs like DV cameras do.
    Good options for you are the Matrox MXO2 mini...$450...coupled with an HDTV. Or a Matrox MXO (DVI connection) coupled with an Apple 23" display gets you good quality.
    And there are the Decklink Intensity and Intensity PRO cards as well, and the AJA I/O Express...
    You can, however, view HDV out via firewire as DV...lowering the resolution to that of DV, but still viewable. This is not full quality nor should it be used to judge the quality of your footage or used to color correct to. This is just a way to view the footage on a large monitor.
    Here are some examples of some of the possibilities:
    - DV or HDV sequence output to an SDI signal on a third-party interface
    - An uncompressed NTSC or PAL sequence output to a DV FireWire output
    - An HDV sequence output to a DV FireWire output
    Sequence and output formats must have compatible frame rates. For example,
    sequences with a frame rate of 60, 30, or 24 fps can be output to a 30 fps device,
    but not to a 25 or 50 fps device.

  • MPEG2 Sound but NO Video on playback

    I have QT Pro w/the MPEG2 Plug in (both current version) running on OSX 10.4.11 and when I try to open/play a file I get sound but no video. The file works fine with VLP and if I use Handbrake to encode the file in MPEG4 it will play. Why doesn't the MPEG2 file play? That's why I bought the plug in... Is there some other magic that needs to be done?

    I looked at the encoding and it was MPEG so now at least I understand the QT not playing part. Yes the original file was from TIVO downloaded via TiveDecode Manager. I was hoping not to have to do any more encoding to get it to play in QT (want to use a Mac Mini as a Media Center). Using Handbrake I can encode to MPEG4 which does play just fine, it just can take hours to encode. If anyone knows of a better way please let me know. I know on solution is to use VLP as the player but it's not supported in Front Row (from what I can see). Thanks for the help Matti..

  • TS1894 After sync my iphone my videos have sound but no picture in quicktime.

    My videos that I sync through iTunes have sound but a black screen when trying to watch through Quicktime.

    for mirror no
    for displaying photos or playing video from supported apps it should work
    I have the same cable and the component (same connectors but 5 of them vs. composite's 3 (where 2 being audio))
    both my composite and component works with my tv with both my ipod touch 3g iphone4 and ipad2
    composite really is the lowests quality format guess it's because of the resolution that it support that it does not support mirror
    and the reason iphone4 does not support mirror is because it's video chip don't support converting what it display into  H.264 in realtime same reason why only newer macs support airplay mirror too

    VLC plugs directly into pulseaudio, while the firefox flash plugin uses ALSA to play sound.  Do you have the pulseaudio-alsa package installed?
    I have had a similar problem before.  Sound would occasionally be controlled by ALSA and occasionally be controlled by pulse (the pulseaudio-alsa package did nothing).  As far as symptoms, sometimes other applications would not produce sound while a flash video was playing and vice versa.  Ultimately, I just removed everything pulse/ALSA-related, deleted (and backed up) my configuration files, and installed all related packages anew.  It works now.  I still don't really know what the problem was.

  • Why have I lost video sound on my ipad?

    Why have I lost video sound on my ipad?

    Try this  - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
    Check your settings. The iPads have a small switch on the right edge. It can be used as a rotation lock to keep the screen from automatically reorienting itself as you move around, but you need to have the tablet’s settings configured properly. That same switch, right above the volume buttons, can also be set to function instead as a mute button to silence certain types of audio.
    If the switch is set to work as a mute button, you can change its purpose to “screen-rotation lock” by tapping the Settings icon on the home screen. On the Settings screen, tap General on the left side, and on the right side of the screen flick down to “Use Side Switch to.” Tap to select Lock Rotation or Mute to set the button’s function. Even if you set the side switch for your preferred use, you can still mute the Mini or lock the screen. Just double-click the Home button, and when the panel of apps appears along the bottom edge of the screen, flick the row from left to right with your finger. Tap the icon on the far left side of the row to either lock the iPad’s screen or mute the iPad’s alerts, notifications and sound effects. Music, podcasts and video are not muted unless you turn the volume all the way down.
