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?

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.

Thank you!

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.

Did you replace the motherboard yourself?
Didn’t you forget to plug in the audio cable into the motherboard?
You can see the audio cable in step 22 in the following Compaq Presario v6000 disassembly guide: http://www.insidemylaptop.com/disassemble-compaq-presario-v6000-laptop/
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?

I have a toshiba satellite l505 and my headphone has been loosened, as in someone put something in it that was too big. do you know where or how i can and should get it replaced?

Unfortunately, the phone jack is soldered to the motherboard. You can see it this guide: http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L505-L505D/remove-laptop-motherboard-1.htm (STEP 23).
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.

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.

I really doubt that you can find this connector anywhere. Toshiba doesn’t sell them separately.
Maybe you can use this technique in order to fix the connector? http://www.laptoprepair101.com/laptop/2009/11/17/fix-broken-keyboard-connector-on-laptop-motherboard/
I think you have same type of the connector.

ps. I am looking to contact the creator of the amazing Toshiba disassembly guides published at http://www.irisvista.com. I would appreciate an email or forum address.
