Some video files playing with no sound, or with voice muted (like karaoke mode).

  1. Hi. I am not sure which forum I should post this in -- I tried Windows Forum, but after a week nobody has answered, so I will try Software.

    I am having a problem with my PC when trying to play video files (primarily), and am hoping that you can help me resolve this issue. My PC is running Windows 7 Ultimate. If there are any other PC details that you need, please tell me.

    Two weeks ago (12/10) my PC started acting strangely when I try to play video files. In some instances there is no sound at all, or the sound is garbled, but most often it is the human voices in the soundtrack that are muted to the point of being inaudible (background music, however, is usually unaffected, which suggests to me that the modification might be related to the "karaoke function" in NVIDIA); yet some files play normally. The logical thing would of course be to look at the NVIDIA control panel and see if somehow karaoke mode has been turned on (I have never used this feature, but from what I have read on line NVIDIA has the ability to mute human voices while leaving the rest alone), but the control panel is inaccessible (it will not open; and I get an error message that shuts the control panel down if I try to open it). Removing the driver and letting Windows download a replacement did nothing to help.

    The issue, as I said, is limited to certain video files (while others play without any problems, and a small number have no sound at all or sound that is badly garbled). This is true regardless of which (of several) players I have tried (and I tried deleting the players and reinstalling them, but that did nothing). The vast majority of my Mp3 files play just fine (in WinAMP), so whatever it is appears to be targeting video media. Also, while some CDs that I have burned myself work perfectly, others do not (the same sound issue); and the commercially produced DVD discs that I have (not many, so I do not know if it is a general rule or not) do not seem to be able to play at all. Likewise, streaming video presents in the same way -- some have sound, some have none or garbled, but the majority have the voice muted while the background music is unaffected. Therefore it seems not to be something that corrupts the actual files (CDs and DVDs are burned onto discs), but rather interferes with the data between the files and the speakers.

    My first thought was that it might be a malware issue, and so I posted in the Malware Forum first. But Broni assures me that my machine is clean, and he suggested that I try one of the help forums. It seems it could be a hardware issue (video card is going bad), or a software issue (some sort of corruption in the NVIDIA drivers, for example).

    There is no logic to the sound problems: the distortion seems to follow no fixed pattern, some files play normally for a while, then suddenly they do not play in parts, with varying degrees of loss of certain parts of the audio-track (though it seems the parts that play and the parts that do not remain the same every time the file is played); and in a couple of instances, the video does not play too (what shows up are a series of "stills"). Since whatever it is appears to be blocking access to the NVIDIA control panel, I suspect that the problem might lie there.

    Thank you very much for your time, and for anything that you can do to help.

    Give us your system specs please so we can know what we are dealing with.

    Merry Christmas -- or Happy Holidays -- to you both!

    The O/S is Windows 7 Ultimate -- 32-bit Operating System.

    Thank you, David Bailey. That was the first thing I tried, but the problem is that the NVIDIA download page does not have a driver for the 32-bit O/S, I do not know why. (I also installed JAVA from that page, but it seemed to do no good with helping them to analyze the system.) I tried manually uninstalling the driver and letting Windows "find" the correct one. I have no idea where they find it, of course, but there was no change.

    MaikuTech, sorry, what other details do you need?

    Thank you both for taking the time to help.

    Yes. I tried that first. But there is only the option for 64-bit O/S (Windows 7 Ultimate), while my machine is running the 32-bit version.

    However, I did not see the options below which offer with "beta and older drivers." (My eyesight is not good -- I had bilateral cataract surgery two years ago, and have no peripheral vision, meaning I can see what I am focused on, and nothing else. It really sucks.)

    Can you tell me: is there a way to gather data on the make and number of the video card in any way other than taking the PC apart? I seem to remember that there was some kind of software that could generate this information non-invasively....

    Mobo name and manufacturer, cpu name, mainly your gpu model name and number.
    https://www.cpuid.com/downloads/cpu-z/cpu-z_1.82-en.exe

    That should reveal most of your system specs info to you.

    Thank you. Yes, that is what I was trying to remember. I guess I had that on the hard drive that failed.

    Ok, I ran CPU-Z. Checking the Graphics information now....

    Downloading the driver....

    Thank you for your help! I would have never figured it out without it! And this teaches me that when Windows says it is installing a driver or something, not to trust that it is really downloading it and installing the latest version.

    Have a great day, David!

    No problem make sure to keep that current nvidia stored somewhere safe in case you need to reinstall again.
     
  12. I never did trust Microsoft to install the right driver. :(

    A good suggestion: I did that as soon as I installed it earlier today!
