Audio and Video issue with Windows 8.1 upgrade on Ideapad n585

I upgraded my Ideapad N585 to Windows 8.1 the other day, took forever, but it made it through.  Unfortunately, I now get boot erors for the Dolby software, and the AMD Vision/Catalysyt Control Center.  Neither of these programs are able to start, from startup or even manually.  They just won't run.  Sound seems to come out fine still, but I do have video issues. 
First off, my computer doesn't seem to recognize a HDtv as a monitor through the HDMI port.  I still get an image, but it's set to current screen resolution instead of 1080i.  I tried using the detect button to force it to look for a second monitor (my TV), but it showed nothing connected, though at the time I was using two screens.  Now my monitor's screen resolution seems to be a little higher than my TV's, but it doesn't fit the screen properly, and will sometimes put a black border around the desktop, not using the full screen.  I have also noticed, that when plugged into the tv, if a background program like a screen saver starts (and I am one of the few people who still use them, I like BOINC, sue me), it will reset the screen resolution to what it requires.  When the program exits, the screen resolution stays, and that becomes the new max screen resolution until I restart the computer.  So far, it only does this through the tv, if I run the laptop monitor alone, it doesn't happen.
I did try updating the software with what's available through the support site, but nothing happened.  I even went as far as to use the Windows 9x~XP standbys of completely uninstalling, manually removing everything from the system registry I could find relating to these two programs, and then finally reinstalling the software.  Giving the audio and video a complete clean slate to work from, and got no positive results.  I restart the computer, Dolby and Catalyst won't boot, and blind to HDtv.  Problems as described above still apply.
Anybody else have this issue?  Anybody got a fix?

have you found a solution to this?
My computer updated to 8.1 without my wanting it to, I have the same problems as you. I installed the video driver because the brightness was locked on what I had it. (the bar would move but did not change)
I searched for brightness and n585 and I was able to find a driver, now brightness works but HDMI still does not. When I plug in the TV both screens go black with all 4 options in the "project" screen.
*edit*
this worked for me i stumbled across this
I unplugged the power cable with the hdmi cable plugged in. Hit (windows key+p) scrolled to duplicate and it worked.I plugged in the power cord back in and it still worked.

  • Audio and speakers issues with the new iTunes 7

    Hi,
    I also have an audio problem after installing the new iTunes 7. It seems after iTunes have finished "determining the gapback playback information", all audio from iTunes and Quicktime only comes through my two front speakers. I have a 5.1 setup for my computer and it seems is only a iTunes and Quicktime issue since Windows media plays the audio just fine. Anybody know what the issue could be? I'm on Windows XP by the way.
    I have checked my speaker setup and sound card and this problem does not occur in Windows media or any other media software. It seems that it only occurs with iTunes and Quicktime.

    Yet another person with the exact same problem, with the same sound card. Everything is up-to-date. I've tried all of the other "fixes" but its either done nothing, or given me use of my rear speakers but added an awful awful ear shattering static. I've tried everything. I even stood on one foot.
    Furthermore, my EAX options do not work with iTunes 7 either, though they work with the older versions. I can't even adjust the speaker balance (front to rear, right to left). This is an isolated problem, only with the new iTunes and QuickTime. Everything else on my computer works just dandy, and cooperates with my speakers (5.1 surround) and my EAX settings.
    Edited because I said video card, not sound card.. I'm tired, been trying to fix this for an hour.

  • Windows 8.1 Audio and Video issues

    I recently updated Windows 8 to 8.1 on my 2012 MacBook Pro and it now appers that Headphone/Line In have stopped working.
    This only occurs in Windows mode, when running in OS X Mavericks the issue does not occur so I am assuming that it is a driver related issue rather than hardware.
    I also have an issue with dual monitor setup, if I attempt to change the resolution or go from Dual to Single then back again, it fails to locate the second monitor again.  Once again, this all worked with no issue before the 8.1 update and no issue occurs while running OS X.
    Has anyone else experienced these issues and/or know how to resolve them?
    I have gone through device manager and it indicates that all drivers are up to date.

    i too have the same issue.  I did a fresh Bootcamp install of Windows 8.1 64-bit on my mid 2011 iMac and my built in audio and headphones have stopped working on the Windows side.  OSX Maveriks is ok. 
    i also went to the device manager and all of my audio drivers are up to date...still no sound.
    i have uninstalled and reinstalled all audio drivers, disabled then enabled them several times...still no sound.
    i have unistalled the graphics driver (i read somewhere else that there was an issue with it)...but still no sound.
    can someone help us out?
    NOTE: i have a usb audio dongle that works on windows.  but it only controls my headphones.  when i plug in the headphones into the built in audio jack on the iMac it doesnt work.

  • Display and driver issues with Windows 7 on i5 MBP

    Hello-
    I just purchased one of the i5 Macbook Pros, and set out to get Windows 7 working through boot camp. I did this on an older model (32-bit) previously with no problems.
    This time around, installation of Windows worked fine, but I have had some trouble getting all the drivers working. The setup.exe program on the OS X DVD didn't want to run at all, I had to do a workaround from the command line that I found on a forum (otherwise I just got a response of "Bootcamp x64 is unsupported on this computer model").
    Eventually I got (at least some of) the drivers to work, but there are still some issues.
    After installing the drivers, things like brightness and two-finger clicking started working. A number of other things still aren't, though:
    - Display: My machine has a 1440x900 screen. But for some reason Windows refuses to go higher than 1280x800.
    - Network: No wireless at all. Windows doesn't detect any wireless capability, and only gets on-line via ethernet.
    There may be other issues, but these are the big ones. Can anyone provide suggestions on what to do to get everything working?
    Thanks!

    I just used winclone to move my Win 7 from my Core2Duo MPB to an i5 MBP and had to do a few updates and have eneded up in pretty much the same place as you. I won't bother installing from scratch. I'm guessing we just need to wait for some bootcamp updates for these new machines.
    For those of you who are looking to migrate your bootcamp partition over, winclone made it easy - I followed the directions for resizing and Win7 boots, does a disk check, then installed many of the new drivers automatically. There are some drivers that are still needed however, wifi and video. I also so a USB driver issue but have to look at that a little closer before I comment.
    Best of luck,
    Simon

  • Embedded audio and video files with Acrobat x Pro

    Can an audio or video file be embedded in a document with Acrobat x Pro & opened with Adobe Reader xi?

    You can place video or sound files onto the pages of a PDF file using the Multimedia button on the Tools Pane > Content Panel. The result is called a Rich Media Annotation, and will play back on the desktop versions of Adobe Acrobat and Adobe Reader.
    The files have to be compatible with Flash Player, so videos need to be in H.264, FLV or F4V, and audio files in MP3.

  • Ultraslim Plus keyboard and mouse issues with windows 8.1 (hesitation/jerkiness)

    I'm just wondering if anyone else is experiencing issues with their Ultrslim Plus keyboard and mouse after the update to windows 8.1? Mine seems very hesitant missing lots of key presses and the mouse pointers movement accross the screen  is jerky. I've uninstalled and reinstalled drivers but it still isn't working like it was yesterday. Batteries for both show as 100% and nothing else has changed.

  • IChat audio and video hanging with no errors.

    When trying to initiate an iChat video conference, a request never pops up for the receiver. However, when someone tries to initiate a video chat with me, the request pops up but when you accept it, it says starting Video Chat but it just hangs. I've turned off the firewall and turned off internet sharing with no luck. I did a package capture and found that all the checksums are zeros instead of what they normally should be. Any idea what could be causing this?
    Thanks,

    Hi,
    Sounds like the issue is with your routing device.
    The visible Invites are sent and received on port 5678 using the USP Protocol
    If you Buddy is not getting is your router letting it through ?
    It does sound Odd that you are getting Invites though as it would be unusual to Block Outgoing stuff and not Incoming stuff.
    iChat 3 then moves to port 5060 (iChat 4 to port 16402) then uses a group of 4 from a list of 20 ports (16384-16403 for iChat 3) (iChat 4 stays just with port 16402)
    It sounds like these are blocked or not open.
    If they were open was it using Port Forwarding ?
    If so does your computer have the IP the Ports point to ?

  • Podcasts and Video Issues With version 7.01.8

    I had 7.0 but removed it and went back to version 6.04. When version 7.01.8 came out I went ahead and downloaded it and my first two songs I played started skipping again. The playback for my downloaded videos and podcasts still have the same problems in this version and 7.0 but not 6.04. The music is not in sync with any video and the music has too much static and erratic breaks. There is a raspy sound and distinct irregular sounds. My music library is playing fine now, though it started as if the problems weren't fix going from 7.0 to 7.01.8 but so far so good. I wish Apple would fix the video and podcast playback problems. I didn't have any problems with version 6.04 and I'm running a Dell Dimension 8200 with GeForce4 TI 4600 AGP Graphics Card. Anyone else have problems with podcast and videos with the this update?

    have you worked through the possibilities from this document, Jerry?

  • [SOLVED] sound and video issues with firefox

    I decided to change my browser due to some problems with the last chromium update (https://bbs.archlinux.org/viewtopic.php?id=182218).
    I'm using the last version of firefox but I can't watch any videos in this browser. I'm having two main problems:
    · There is no sound at all in the videos played. But there is sound if I play something with Clementine or mplayer
    · The videos stop after a few seconds automatically. The videos keep loading, but they are not played anymore.
    This is a weird thing. I can't use a browser! Please some help!
    PS: I change the player on youtube to HTML5 and it's working now

    Hello,
    While the whiteboard itself doesn't have an upload command,
    the FilePublisher can upload images into the Cocomo room. From
    there, your clients can download the image and display it (say,
    through an image component). The SharedWhiteboard can have its
    backgroundAlpha set to 0 - try myWB.setStyle("backgroundAlpha", 0).
    As far as your audio is concerned, it seems as though you're
    compiling against the FP10 cocomo.swc, but aren't requiring player
    10 in your Flex project (check Project Properties->Flex
    Compiler). I'd either use the FP9 swc, or require 10.0.0 or higher
    in the project.
    hope that helps

  • DVD/CD issue with windows 8.1 upgrade

    I have a Pavillion G7 2270us notebook. I upgraded to Windows 8.1 from Windows 8.0. My DVD/CD drive no longer read any DVD nor CD. What can I do?

    Hi,
    Try the following.  
    Open windows Control Panel and open Device Manager.  Expand DVD/CD-ROM Drives, then right click the drive and select Uninstall.
    When done, download and reinstall the Chipset driver on the following link.
    http://ftp.hp.com/pub/softpaq/sp59501-60000/sp59647.exe
    When complete, shut down the notebook by holding down the Shift key as you click Shutdown to temporarily prevent a hybrid boot.  Then unplug the AC Adapter and then remove the battery.  Hold down the Power button for 30 seconds.  Re-insert the battery and plug in the AC Adapter.
    Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu.  Press f5 to load the defaults ( this is sometimes f9, but the menu at the bottom will show the correct key ), use the arrow keys to select 'Yes' and hit enter.  Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.
    As you boot into Windows, the optical drive will be reinstalled, but let windows fully load for a couple of minutes before checking.

  • Cannot view or play audio or video coded for windows media player, and do not see javascript

    I designed a website that uses a little bit of JavaScript. It displays fine in IE (9), but not in Firefox. Does anyone know why, and what the fix is?
    Also, and more importantly, I coded audio and video files with Windows media player's class id. They will not show or (obviously) play in Firefox. I downloaded and installed the plug in for Firefox, but no change. I'm sure I'm not the only one to have run across this problem, and I'm surprised that Mozilla hasn't built a fix in the 4.0 version. So, any ideas out there?
    Thanks!

    Firefox won't play the media file if there is a classid specified in the object tag. You either need to use conditional code to hide an object without classid for Firefoz from IE or use an embed for Firefox.
    <pre><nowiki><object id="(ID)" type="application/x-oleobject" classid="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6">
