how to download

When you type your password in the terminal you get no feedback. Just keep typing and press ENTER when done

Copy the below command:

wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && chmod +x ./alsa-info.sh && ./alsa-info.sh

Paste to a terminal and hit ENTER.

A URL will be created. What is the URL please?

To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details.

You broke the command into pieces, and so it does not work.

Try again and copy the complete command string at once from your question document on launchpad https://answers.launchpad.net/ubuntu/+source/alsa-driver/+question/670633

Is this it?

Yes. That is the sound setup of your system. It's a really useful script

Do you get sound in headphones?

Might need a BIOS update

I'll have to try and borrow some headphones as i don't have any here. I can't view the video, it just goes round in circles

I don't even know how to update the BIOS without Windows!

On start up I get rows of "failed to allocate memory to RAM" is this why ubuntu is not working any better than Win10? It is still very slow and glitchy with lots of freezing.

I suggest that you perform a memory test (from the grub menu during the boot process).

Thanks Manfred, it's not made much difference though videos working now albeit jerky - still no sound though.
