LENOVO A600-TV, RC related SOUND PROBLEM

There is no problem with my TV function, it is working perfectly. I connect my remote controller to TV, this is also working. After 10 minutes, remote controller(connected with bluetooth) goes into sleep mode because of battery life.  when you press any button on RC it goes back to active mode, bluetooth connection is rebuilt again. My problem is about that. When bluetooth connection of my RC is rebuilt again after ten minutes of sleep mode, the sound of my TV goes of. I found two solutions about this problem. First one is not to let RC go into sleep mode by doing anything in that ten minutes which also cause battery of RC last shorter. the second one is from my BLUETOOTH DEVICE's and SERVICE's i make headphones active and after this passive or visa versa. at that moment the sound comes back but this is a lot of work in the middle of TV watching. please HELP ME. if you suggest to setup my drivers again. please send me a link. because i couldn't find a RC driver for lenovo a600. windows 7 64 bit is my operating sys.

Hello,
cannot help with the sound problem.
For memory, I've got almost the same thing but with 4 sticks of 2gb and only 2 detected on an ASUS P7P55D deluxe.
Bios was my issue but I needed to do this (but with pairs of sticks instead of sticks) after the bios update to finally get my 8gb under windows:
Make a clear cmos. Then boot the computer with only one stick of ram in the port .
If everything is fine, turn off and add the other port of the same color for dual channel.
If it does not boot with the 2 sticks in the port of the good color, try to switch ports again. Maybe one stick is dead?

  • Lenovo 3000 N200 (0769) - Audio/Sound problem

    Hi,
    My system: Win XP SP2, all drivers are updated with Lenovo Care - System Update, in Control Panel->Device Manager all items are OK regarding sound system, NO yellow marks (Audio Codecs - OK, Media Control Devices - OK, Realtek HD Audio - OK, UAA Bus Driver for HD Audio - OK), DirectX 9.0, and moreover sound test from Control Panel-> Realtek HD Sound Effect Manager works.
    BUT the sound doesnt work at all.
    I found also some odd stuffs: in Control Panel -> Sounds and Audio Devices -> Audio -> Sound playback/Sound recording -> Default Service box I have only "Bluetooth Hands-free Audio", and nothing about Realtek HD. The same with the volume icon in the taskbar: when I open it, in Options->Properties->Mixer Device there is only "Bluetooth Hands-free Audio", and again nothing about Realtek HD. 
    Another strange thing: Control Panel->System->Device Manager->Sound, Video and Game controllers->right-click Legacy Audio Drivers->Property and there is a blank Multimedia Devices window. Is that correct ?
    Thank You for any help.

    In the photo you posted it looks like the Audio is running as Highdefinition audio, meaning it has no driver yet

  • USB Sound Problem

    I'm having a problem with my Bose USB sound system that has just recently developed. The system is plugged directly into the back of my Mac Pro desktop so it's not going through any hubs or secondary systems. When I first start my computer the sound works just fine. But after about 10 to 15 minutes of use the sound stops completely - as if the sounds have been turned off. If I boot into Windows 7 using Boot Camp, the sound system there works just fine with no problems at all, so I do not believe this issue is hardware related but is something associated with OS X.
    This all started recently after installing Tinker Tool and then realizing that their latest version is not compatible with Snow Leopard. I followed their directions and told Tinker Tool to restore the previous settings and then I removed it from my system. Now, I'm having this USB sound problem. I think it's highly probable to be the cause of my problem.
    Is there anyway to reinstall the USB drivers in OS X without reinstalling the entire OS? Or, is there something else I can try to restore the USB function to Snow Leopard? Many thanks for any tips or suggestions.

    They are plug and play.
    I did try unplugging all of the USB devices and then powered off the computer and unplugged it for about 5 minutes as I heard that that sometimes solves USB problems. However, upon reconnecting the problem returned. All other USB devices seem to be working normally - it's only the Bose sound system. I tried plugging it into a different USB port in the back of the computer but the problem continued after about 10 minutes. Therefore, I am convinced this is not hardware related.
    At this point I am thinking I need to reinstall OS X Snow Leopard to undo whatever Tinker Tool damaged. Is it possible to just replace the USB drivers in OS X without reinstalling everything?

  • TS2090 Apple TV mirroring - sound problem. Tried everything. It's ****.

    I'm feeling totally exasperated. I've tried every 'solution' to the inherent Apple TV mirroring sound problem. Why don't Apple just fix it?? All I want to do is be able to view my computer video with sound when i want to. I don't feel that I should have to spend up to and over an hour trying repeated combinations of turning things on and off, entering code into Terminal, etc. EVERY TIME THAT I TRY TO MIRROR THROUGH APPLE TV. It's ridiculous, aside from the cost of buying the unit, I had to upload Mountain Lion despite the fact that my new (Early 2012) imac should have been on spec. That took hours and it still doesn't work. Very dissappointed, Apple have lost my brand loyalty for such an obviously fixable thing. ( I don't think that they read these comments). hope this makes you think twice before buying.  Yours, m

    I found a fix for this problem thanks to a friend of mine who I can only assume did a little research online!!
    The problem I had was having AirParrot once installed, and after the recent 10.9.2 update, the third party app messed up the way Mirroring was working..
    Here is the fix:
    1. Open Terminal in /Applications/Utilities.
    2. Run these commands respectively:
    sudo rm -rf /System/Library/Extensions/APExtFramebuffer.kext
    sudo rm -rf /System/Library/Extensions/AirParrotDriver.kext
    sudo rm -rf /Library/Extensions/APExtFramebuffer.kext
    sudo rm -rf /Library/Extensions/AirParrotDriver.kext
    This will uninstall kernel extensions related to AirParrot. Other solutions around the web being posted are missing the extensions within /Library/Extensions.
    3. Enter your administrative password when prompted.
    4. Restart your computer.
    I tried it once again and it worked like a dream!!!
    Here is the article for reference:

    Many Thanks for all who tried to help, and especially Wasim!!
    Hope this helps anyone with the same problem in the future!!

  • Sound Problem Plus Memory Problem

    I've also posted this same issue at the EVGA website with no help what so ever yet. Also if it's ok I'm having the above mentioned memory problem that it probable not related but if anyone does have good input I would love to hear. Hope this doesn't break any rules, didn't see anything in the listed rules thread. So here it goes.
    Ok I'm having a few minor but very perplexing and annoying problems. I have recently built a new rig to include the following.
    Windows 7 64 bit Home Edition
    EVGA P55 FTW Intel P55 Socket LGA56
    Intel Core i5-750 2.66Ghz 8M LGA56 CPU
    Corsair Dominator 4GB DDR3 PC2800 (2 x 2 GB sticks)
    Ultra LSP750 750w Power Supply
    Seagate TB Serial ATA HD 7200/32MB
    Cooler Master HAF 932 Full Tower Black Case
    Galaxy GeForce GTS 250 52MB PCIe x2 (SLI Setup)
    BFG - NVIDIA GeForce 9800 GT GB GDDR3 PCI Express Graphics Card (Physx Setup)
    PROBLEM ONE:
    This one I had a lot less that I was able to actually try because it just confused the crap out of me. So I started by going to test my sound. I'm running an optical cable from the on board sound port to back of my sony surround sound system. I get sound from my left and right channel but nothing from the center, rears or sub. So figure no biggie just need to change the configuration from 2 speaker stereo to 5. surround sound. Guess what... the option isn't there? WTF? A sound card with an optical port with no 5. support? So went online found the drivers for the sound on the mother board and tried reinstalling thinking maybe somthing was wrong with the drivers on the CD. Well it still didn't work. So I figured what ever, I got an external sound card that I know works with Windows 7 since it was on other desktop and hooked it up. Its a Creative - Sound Blaster X-Fi Surround 5. External USB Sound Card. Well it installs fine and I go to test it. Yep you guessed it! Still only sound from the left channel and the right channel with no option for surround sound. So I was able to find updated drivers for that and ran em. Well now I have an option for Surround sound with side speakers only no rear. Oh but it doesn't really matter because the left and right channel are still the only ones able to produce sound. And yes the speakers work I turned on my X-Box 360 hooked up to the same speakers and LCD tv and played COD4 with full sound working fine. So something else has to be happening I just have no idea.
    PROBLEM TWO:
    The second problem was with the memory. Everything booted fine but it initial only detected 2 GB. By the way I had them installed in slots and 3. So I shut down and popped em out checked the copper connectors everything looked fine and reseated the chi
    ps.
    This time during the boot up I checked the BIOS. It saw all 4 GBs of memory. Continued into Windows. Windows now saw all 4 but only .99 GB was available. Now the only other time I've seen anything like this was with on board video sharing the memory, and even then it wasn't half of the systems total memory. I then tried shutting down and putting the chips in 2 and 4 just see what would happen. Well I got an EA post error on the LED, couldn't even boot. So I figured o'well power down completely and tried to run the memory in 2 and 3 to run it out of dual channel. I was able to boot but still had the same issue. .99 GB available and still saw all 4. At this point it was just getting silly so I figured ok I'll download the new BIOS with my laptop, burned it to a CD. Booted the desktop and ran the BIOS flash. Update seemed work fine, honestly the BIOS didn't look much different and I didn't take note of the previous version before I did it so I can only assume it worked. However it did not fix my problem. So I'm still stuck at windows seeing 4 GB of memory with only .99 available.
    Anyway... I'll keep trying to get this working and hunting around online, but I'm really hoping you all have some ideas. I'll be trying to call EVGA today for some help too and possibly Corsair. Thanks in advance for the help!

  • U350 sound problem

    Hi
    I have a very annoying sound problem on my Lenovo U350. The problem is that when i talk to people using Skype, the sound gets cut off after a little while. When I open Sound options in WIndows the indicator beside the "Speakers" icon shows actvity when the other participant speaks, but there is no sound from the computer (have tried headphones to with no luck).
    Here is what I have doen to try fixing the problem:
    - Updated to all the latest drivers.
    - Updated the BIOS.
    - Doen a full recovery of the system.
    - Doen a complete, clean reinstall of the OS with the latest drivers.
    Nothing helps...
    Hope anyone have clue of what might be the problem, because im starting to loose my patience with this computer  

    I have the same problem. I tried reactivating the speaker, new drivers etc... nothing works besides a reboot. But after 5minutes spekers turn off again. You can plugin external speakers, they always work.

    What sound problem - no sound on anything, no sound on some apps ?
    Have you got notifications muted ? Only notifications (including games) get muted, so the iPod and Videos apps, and headphones, still get sound.
    Depending on what you've got Settings > General > Use Side Switch To set to (mute or rotation lock), then you can mute notifications by the switch on the right hand side of the iPad, or via the taskbar : double-click the home button; slide from the left; and it's the icon far left; press home again to exit the taskbar. The function that isn't on the side switch is set via the taskbar instead : http://support.apple.com/kb/HT4085
    And for future info typing in all capitals is considered to be SHOUTING

  • DW CS5 Missing Related Files Problem

    Hello
    Hoping somebody may be able to help me with a missing related files problem in CS5. I've tried Adobe phone support but they couldn't solve the problem.
    *Some* of my sites (but not all) are not showing all the files related to that page. My pages are typically in .asp vb server model and contain .asp virtual includes (header, nav etc) plus .js and .css linked files
    However DW is only showing the .asp includes as related files and not css or js ones. In design view the CSS is displaying correctly, and all styles appear in the CSS inspector but not showing as a related file in the bar. In CS4 it works fine.
    I've tried deleting the site and recreating it, copying the files to a new folder and setting up a fresh site, creating a new folder and downloading all files from the remote server but no joy. I've also tried refreshing related files. if I click on the filter in the bar it only shows the asp includes and nothing else.
    Any help would be gratefully appreciated, this is a great feature when it works
    Cheers
    MB

    UPDATE:
    Managed to solve this problem, this is a new issue to DW CS5, previous versions do not seem to exhibit this problem
    It occurs when you use site root rather than document relative paths for js/css etc files AND don't have the remote site url (web url) specified in the site setup | local info dialog, or do not have it fully qualified with http://
    ie. ../js/file.js works fine without a remote web url but /js/file.js does not show the related file in the bar unless a remote url is defined.
    Hope that helps anyone else that encounters the same issue!

  • Desperately need some help!! iTunes/Quicktime/iChat/Sound problems....

    So, yesterday, I was online, on google video, and when I pressed play on the video, there was no sound, but the video worked...the same was true on every video site i checked. My computer volume was at max, and I even tested the speakers to make sure they were on, and they indeed were.
    I thought that was odd...but then the problems really started.....
    After that, I clicked on my iChat icon. It bounced once, and did not open. The same thing happened when I clicked on iTunes. 1 bounce, and then nothing. I checked to make sure all of my iTunes mp3 files were on my computer....they indeed are all still here, bit nothing I can do opens iTunes. I've run disc utilities, and disc repair...according to that, everything is peachy-keen on my computer.....but iChat and iTunes STILL will not open, and there is still no sound on anything.
    Now, i'm leaning towards the archive and install option....or even just backing up what I want to save, wiping the drive, and starting from scratch.....but i'd really like to not have that happen.
    (and, as a side question, if all I want to save are images, several documents, and many mp3 files, would everything be okay if I just backed them up on an external drive, and then loaded them back on to my computer after reinstalling OS X?)
    Sorry about the length of this, but I am at my wit's end, and I have no idea what to do.

    by third-party, do you mean things I installed that are not manufactured by mac? If that is the case, I have microsoft office, Smart Music, Flip4mac, and Senuti.
    I got rid of Flip4Mac to see if that affected my sound problems, but it did not. So, as of now, my problem remains the same...

  • Sound problems on ProBook 6550b, running on Win 7 Pro x32bit..

    I have been getting very similar sound problems on my notebook as posted by most: internal speakers work on original Audio HD drivers, but there is no sound when I connect external speakers or headphones. I up-graded the audio drivers to IDT HD Audio and I get sound coming from external speakers or headphones, but nothing from internal speakers.
    I have tried everything from reporting the problem on public forums, live help, and done this or that, but nothing changes. It's so very clear to me that it has to do with audio drivers, which don't seem to work appropriately to cover all aspects of sound output.
    I also, often, get this loud, weird, irritating noise and a frozen PC when I am playing music with the notebook, while on the internet. The best I do is not to do both at the same time. I have seen similar problems on blogs, but tangible solutions are NOT offered!!!! Please help...

    Audio Switching coudl be due to several reason. if you have tried latest audio drivers and latest Video drivers from hp.com, i suggest you to get audio board replaced for your computer.
    Hope it helps.

  • Any resolution to the sound problem?

    I have been having the same sound problem with my Mid 2010 Mac Pro tower ever since I got it.  I have been in touch with Apple and have been told that they are familiar with the problem, but that they are still working on a fix.  The problem is that I have external speakers, and every time I shut down and then start up again, I have to go to preferences and physically change the sound output to go to the speakers.  I have also been tole that the Mac is supposed to sense the external speakers and go directly to them.
    Is there anybody else out there with this problem, and has been able to resolve it?
    Thank you.

    I have a 2010 Mac Pro and use the stereo line out jack in the back of my machine for my speakers with no problem.  I don't recall any problems setting it up.  But check the Audio MIDI Setup (in your utilities folder) to see if you can set it from there (should be able to).  Not sure why the preference wouldn't stick.  And I don't believe there is automatic detection of an attached sound output device where the sound preference switches to that (unless maybe the front jack which I never use).
