    The Acer Iconia A1-810 has a fairly unimpressive headphone output, so i opened her up to see what can be done. Here is how you get louder sound out of it.

    Tools needed:
    • Soldering iron with fine tip
    • 0.5mm solder
    • Fine insulated wire, 0.15mm diameter or smaller
    • Flux paste
    • A steady hand :)
    Instructions:
    • Take the back off your tablet. It is only held in by clips so you can take it off with your fingernail. Start at the MicroSD slot.
    • Solder wires as per the picture (careful with the resistors on the right, they are VERY VERY SMALL)
    • Clean up
    • Enjoy a louder tablet.
    Note that what this does is bypass some filtering so there may be a little more noise on the output, especially if you are connecting your tablet to a larger sound system. But if you're just using it with headphones it will sound louder with no issues.

    The complete solution would be a bit more involved and needs some parts that i don't have on hand right now. Expect some updates soon..

    I have also acquired the full schematics for this tablet if anyone needs them.
