Audio board also known as sound board

Laptop audio sound board

In most laptops the audio board also know as sound board is integrated into the motherboard. In other words, it’s a part of the motherboard and cannot be removed or replaced separately.

Why the audio board cannot be removed? Because the audio chip is soldered to the motherboard.

Audio sound chip

If the audio board fails, you’ll have to replace the whole motherboard.

AUDIO BOARD FAILURE SYMPTOMS AND TROUBLESHOOTING TIPS.

1. There is no sound from internal speakers or headphones.

  • Make sure the volume level is not set to minimum.
  • Make sure the volume is not muted.
  • If the volume is not mutes and volume level is not set to minimum, but you still have no sound, try reinstalling the audio driver.
  • If reinstalling the audio driver doesn’t help, try reinstalling the operating system.
  • If nothing helps, it’s possible you have a problem with the audio board.

2. Headphones are working fine but there is no sound coming from the laptop speakers.

  • Sometimes contacts inside the audio jack get stuck and there is no external sound because of that. Try to plug and unplug the headphone connector into the jack very quickly a few times.

    Hello Mr. Repair Man.

    I’ve had my Toshiba Satellite apart (to re-solder the DC input back to the motherboard) one too many times. The strain of getting past the bottom housing was too much for the volume control wheel. the little bugger popped right off it’s shaft. Is there any place where the part can be gotten for something near it’s actual worth, or should I just hard-solder the contacts on the mobo?

    Thanks in advance for any help!

    I really doubt that you can find the volume control wheel separately from the motherboard. Unfortunately, Toshiba doesn’t sell them separately.
    I guess you can search for a similar damaged motherboard on eBay and unsolder the volume control component from that board.
    Also, you can search pchub.com
    Sometimes, they sell some really rare parts pulled from old laptops and maybe you can find something useful.

    I accidently tripped over the headphone cable and broke the audio connector inside the laptop. Is it possible to repair this connector without replacing anything?

    It’s hard to tell without looking at the damage. The audio jack is soldered to the motherboard.
    It is necessary to disassemble the laptop and take a closer look at the jack inside. Maybe it just needs to be resoldered. Maybe it has to be replaced.

    Try reinstalling the operating system from scratch. If the problem with sound still there, most likely the sound card is not working properly.
    Unfortunately, the sound card is integrated into the motherboard. If the sound card failed, you’ll have to replace the entire motherboard.

    Toshiba P100 – in disassembly I damaged the cable connecting the motherboard to the audio board. I will not be able to repair it. Where do I look, generically, for a replacement? To Toshiba or the aftermarket ? At this point I am new to the sourcing of laptop parts.
    This is a useful resource communicating with the expert.

    I really doubt that you can find this connector anywhere. Toshiba doesn’t sell them separately.

    Unfortunately, the phone jack is soldered to the motherboard.
    If the phone jack is damaged, it has to be de-soldered and replaced with a new one.
    Alternatively, you can de-solder the microphone jack and solder it instead of the damaged headphone jack. I believe these two jacks are similar.

    Hi, I’m having a problem with sound on my compaq presario v6000 running windows 7. I have no sound what so ever through my internal speakers, headphones, or external speakers. I had sound up until my motherboard was replaced. Once it was replaced I had no sound AT ALL. I have since then updated my driver, bios, and have troubleshooted the sound. It shows that everything is working fine, yet there is still not sound. I have also replaced the audio ribbon cable, and media panel. When putting in the new media panel, the buttons lit up with the lights but still no sound. After trying to switch back to the old ribbon cable and panel, I have lost all lights and now have no button sound or audio of any kind. It has been like this for months now and am starting to feel hopelessly desperate….ANY help would be greatly appreciated. The only thing I have not tried is reinstalling the OS, not sure if that would help at all? Is there any other components that would control or affect the sound? What can I do at this point?? PLEASE HELP!!

    Did you replace the motherboard yourself?
    Didn’t you forget to plug in the audio cable into the motherboard?
    It’s possible your new motherboard has failed audio chip. I believe the audio chip is located on the motherboard, not audio board. The audio board has only volume control and audio jacks, but the sound is controled by the motherboard.
    Instead of reinstalling Windows OS, try booting your laptop with Ubuntu OS (live Linux CD). After you booted, click on the speaker in the upper right corner and try changing sound theme. Does it play sound though internal speakers or headphones?

    Hi Repair Man,

    Sometimes when I’m watching programmes on my laptop and suddenly the screen will freeze and the sound jars, and then it sounds like a slowed down record, so you can hear the words but dramatically slowed and distorted. This happens quite a bit, and its only a worrying inconvenience (as far as I know!) but I’d like to make it stop – any ideas? It is a Asus A501j SERIES.
    Thank you!

    I think this could be heat related issue.
    When the laptop start doing that touch the bottom. Does it feel hot? If it’s hot, try cleaning the cooling fan and heatsink with compressed air. Blow air into the fan brill until all dust is gone. After that test the laptop again.

    I’ve been searching different forums for 2 days now and I’ve found onlt one person with the same problem as mine.
    “after upgrading, whether I roll the sound wheel clockwise or counterclockwise, it only lowers the system volume” any ideas ? ?
    He went from Vista to Windows 7. I upgraded the video card from 9700 to 9800gtx. We Are talking Qosmio x305-q705.

    Qosmio x305-q705
    I recently upgraded to windows 7 and now after installing all drivers from toshiba the volume control wheel only takes th volume down but some times if I go slow it takes it up a notch before going back down.

    Any help would be great.

    Karl Says:

    That sounds to me like it would more likely be a hardware issue than a software problem, but you could try reinstalling the drivers or installing an older or newer version of the drivers.
