Does the headphone socket work by any chance .. ie. do you get audio through headphones plugged into the mini jack plug socket ?

Can you also post the output from:
Code: [Select]
aplay -l

Hi, Mark

Have now checked the headphones but still same result.

Here's the output you asked for.

joyce@joyce-Satellite-Pro-P100 ~ $ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: CONEXANT Analog [CONEXANT Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

  Subdevices: 1/1
  Subdevice #0: subdevice #0
joyce@joyce-Satellite-Pro-P100 ~ $ s,

Regards,

Doug

OK, I want to confirm this is an ACPI issue.

Open a terminal and run:
Code: [Select]
sudo gedit /etc/default/grub
enter your password when prompted, an hit enter.

When gedit opens, look for the line:-

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

and change it to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"

SAVE the file, and exit gedit.

Back in the terminal run:
Code: [Select]
sudo update-grub
Now REBOOT.

Is sound now working ?

Be Aware, turning off ACPI will likely result in the system fans running flat out all the time .. but rarely it can result in the fans not coming on at all, keep an eye out for the fans not coming on when the laptop gets warm - if this happens, close down the laptop before it gets too hot and let me know.

Hi, Mark

This sounds a bit scary to a novice like me!!  )

How do I save the file when I've altered the line please, is it obvious?

If as you say the fan doesn't run at all is the only solution then to reverse the last step?

Is there any downside to the fans running constantly apart from the obvious - noise, power consumption and wearing them out?  :)

Regards,

Doug.

Cheers,

Doug.

Yes it's obvious just click "SAVE" at the top of the screen



Good luck

Thanks, Graeme,

Just going to give it a go - if I cock up you'll no doubt hear the cries of anguish where you are!!

Cheers,

Doug.

Hi,Mark

Success! Sound at last.  :)

The fan(s) are running continuously is that something we (sorry you) can do anything about or is it the price of getting sound working?

Either way your patience and hard work has delivered and I'm very grateful indeed.


Regards,

Doug.

Graeme,

Sound now loud and clear - fantastic!

Fans running constantly but maybe Mark knows if that can be fixed.

Cheers,

Doug.

There's probably no EASY fix for the fans.

There is a problem with the BIOS's ACPI function that was probably worked around elsewhere in Windows

We could dig out the DSDT and experiment with making changes, but if the above scared you this will scare you sh**less (it does me) .. this would also be extremely hit and miss, and mean going through about 8000 lines of hex code.

Hi, Mark

I think I've asked enough of you already!!!
 
If I simply changed the line I amended back to what it was I imagine that would solve the fan running  but of course kill the sound again?
I'm just asking in case the lady isn't keen on the fan(s) running all the time as they are very noisy even for me but at least she now has a choice.
I've noticed that since the change Peppermint doesn't shut down it shows the shutting down screen but nothing happens until I press the off
switch on the laptop. I assume that's related to what we've done?
 
I really am very grateful for all your efforts and the time you've spent on this I'm just sorry I'm not able to do you a favour in return.

Incidentally, should I start another thread regarding if I wanted to swop P4 for P5 in due course without losing XP which as I mentioned dual
boots with Peppermint?

Many thanks.

Doug.

Yeah, ACPI handles the shutdown procedure too, so disabling it will almost certainly affect shutdown too.
I'm not sure if it's possible to have 2 lines in the GRUB boot menu, to select either acpi=off or not. It's a bit early in the morning for me to be recommending changes to your boot loader  :P

And yeah, upgrading is probably best covered in a new thread (although I'll be amazed if Mark doesn't write a sticky post about it!)

Hi.

I assumed shutting down was related to the changes it was obvious really even to me!

It's a pity that the only way to get sound means the fan running all the time which is very noisy and also losing auto shutdown.

Seems Toshiba have a lot to answer for.

Cheers.

Mark - ACPI issues come up a lot (at least, disabling it fixes a lot of issues), are you aware of a PPA or something along those lines which have patches to at least granualise ACPI support, if not patching the issues completely? Obviously it would a variety of patches to address the variety of hardware-specific issues, but patching to granualise support wouldn't need to be hardware-specific.

@ cicero

Let's undo those changes, then have a go at patching the broken ACPI tables.

Open a terminal and run:
Code: [Select]
sudo gedit /etc/default/grub
enter your password when prompted, an hit enter.

When gedit opens, look for the line:-

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"

and change it back to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

SAVE the file, and exit gedit.

Back in the terminal run:
Code: [Select]
sudo update-grub

Now REBOOT.

Once rebooted (and audio no longer works) run:
Code: [Select]
sudo cat /sys/firmware/acpi/tables/DSDT > dsdt.dat
you'll then find a file called dsdt.dat in your home folder (that's where you are when you first start File Manager)
can you attach that to your next posting.

Don't worry, it contains no personal info .. just the ACPI tables.



I'm putting these 2 links here for my own future reference:

Mark,

Is this OK and what you asked for?

Do you know how to Access the BIOS to check the Toshiba Satellite Pro P100-PSPA4E BIOS version ?

If so, what version is it ?
