Don't worry, they mean "Student in HP-Forum" that just a kind of title Dr.

You can reinstall window, you don't need a full version a 30 days test version is enought. Just install the new version of the  BIOS, then you can remove windows

Hi Tasmac,

It looks like you followed the instructions correctly except for one crucial point, you need to run

sudo update-grub

after you add the lines into the /etc/default/grub file.

Next, reboot TWICE, and the sound should start to work.

As mentioned by somebody else, if the above mentioned doesn't work, check which BIOS version you have (press F10 repeatedly immediately after you power the machine on and it will take you into the BIOS), if it is less the F.18, you should update it. You can easily get a Trial version of Windows to install, just google "Windows 10 enterprise trial". If you use the built in recovery, it will wipe the entire drive, which would be counter productive 😉

I hope this helps you,

Thanks, venividivici24.

I did follow those two steps.... The file is now changed. I don't know the significance of the aplay -l result, which I might interpret as not recognising any sound device at all. I tried the sudo update-grub again and received this error message:

sudo update-grub
[sudo] password for james:
/usr/sbin/grub-mkconfig: 35: /etc/default/grub: Syntax error: EOF in backquote substitution

I'll try the double boot again...

Double booting again did not solve the problem. I'll check the BIOS version.

You need to fix that syntax error in your grub file, make sure the line you pasted is all on one line and that all quotes are as they should be, then try sudo update-grub, there should be no errors. I have posted my GRUB file below:

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor acpi_osi='!Windows 2013' acpi_osi='!Windows 2012'"
GRUB_CMDLINE_LINUX=""

Thank you, smistry,

That answers my question re retention of the original line. However, I have again got the error on <update-grub>

/usr/sbin/grub-mkconfig: 34: /etc/default/grub: Syntax error: EOF in backquote substitution

I'll do the double reboot, but don't have much hope. I'll let you know....

As expected, the double reboot did not work.

The new full document is as follows:

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

# info -f grub -n 'Simple configuration'

Hi Tasmac, I figured out your problem, I think. This part of your modified line:

GRUB_CMDLINE_LINUX="GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor acpi_osi='!Windows 2013' acpi_osi='!Windows 2012'"

is incorrect, it should be this instead:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor acpi_osi='!Windows 2013' acpi_osi='!Windows 2012'"

In other words, this part:

GRUB_CMDLINE_LINUX=

should not be in front of it. You can safely delete it, my grub cfg doesn't have that line anywhere. That should get rid of the error you are having and enable update-grub to successfully run.

I really hope this works for you,

Many thanks to venividivici24 and smistry, this morning.

Problem solved. I didn't see the duplication.

Ever grateful.

Cheers,

James
