Tried (not working):
sudo alsa force-reload

----------------------------------------------------------------------------------------------------------------------------------------------
Tried creating a file (not working):
sudo gedit /etc/asound.conf containing:
defaults.pcm.card 0
defaults.pcm.device 0
defaults.ctl.card 0

Currently the /etc/asound.conf is deleted to get back to known original state.

----------------------------------------------------------------------------------------------------------------------------------------------
Tried the appending the following options in /etc/modprobe.d/alsa-base.conf
#### Tried appending these one-liners - one-by-one: none worked so far (so I commented them out).
#options snd-hda-intel model=vaio
#options snd-hda-intel model=sony
#options snd-hda-intel model=generic

Then from https://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio-Models.txt

ALC260
======
  gpio1 Enable GPIO1
  coef Enable EAPD via COEF table
  fujitsu Quirk for FSC S7020
  fujitsu-jwse Quirk for FSC S7020 with jack modes and HP mic support

tried again with:
options snd-hda-intel model=gpio1
then
options snd-hda-intel model=coef

Still no sound :)

Hi Raymond, have now used "Pin Default 0x01014000: [Jack] Line Out at Ext Rear" (like a headphone socket but at the rear and the visible ring is yellow) - NOW WE HAVE SOUND ON LEFT CHANNEL !!! Thank you so much - the linux on this machine is at last usable for daily tasks.

The link you have included:
https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/hda/patch_realtek.c?id=d08c5ef2a039393eaf2ab2152db5f07790fa0f40

speaks of "ALSA: hda - Provide missing pin configs for VAIO with ALC260...
Some models (or maybe depending on BIOS version) of Sony VAIO with ALC260 give no proper pin configurations as default, resulting in the non-working speaker, etc. Just provide the whole pin configurations via a fixup."

Is there a way of getting the right channel working as well ? (this laptop used to have WinXP and the normal headphone socket at the side working with full Stereo sound). If there is a possibility of getting full stereo - what is the next thing I should try?

Irrespective if the full stereo is achievable or not - I am very appreciative of you looking at this problem and getting the laptop to be usable at last - Thank you again very much.

Do headphone jack change to true when you plug in headphone?

Do. Mic jack or line in jack change to true when you plug in mic?

You need to use hdajackretask to remove those redundant input pins if not exist in your laptop (e.g. aux, cd,...)

Seem same pci ssid

Alc260 basic model was removed, seem use 0x15 as line out and use mono pin

[Raymond (superquad-vortex2)]

- /* LINE-2 is used for line-out in rear */
- {0x15, AC_VERB_SET_PIN_WIDGET_CONTROL, PIN_OUT},
- /* select line-out */

Hi Raymond, thank you for the suggestions of things to try.
Also thanks for the tip re David Henningsson's ppa and his hdajackretask:

$sudo add-apt-repository ppa:diwic/hda
$sudo apt-get update

[This is up to 14.04 Trusty but seemed to work well enough on 16.04 Xenial Final Beta]

Played around with it (If one makes a mistake, one can press 'Remove boot override' button, shut down computer, wait a little,
then power back on - should be back to where you started.

Still - the only sound is the MONO SOUND from the 0x15 at the back
/* LINE-2 is used for line-out in rear */
- {0x15, AC_VERB_SET_PIN_WIDGET_CONTROL, PIN_OUT}.

I don't know enough at this stage to recompile kernel etc in the effort to re-introduce the 'Alc260 basic model' back in again?
I will leave it at this time, but obviously if you happen to know of any changes in this situation - would be glad to hear it.
Also if you / anyone else happen to hear of more things to try - please let me know - will attempt to try them out.
Again, thank you for the help so far.

"Do headphone jack change to true when you plug in headphone?"
The 'headphone' is always present as the only possible output option - it doesn't vary.

Do. Mic jack or line in jack change to true when you plug in mic?
No.

[Art (aglotus)]

"Do you find the missing speaker from windows inf" - please see below.

OK I have now re-installed Ubuntu MATE 16.04 Final Beta to dual-boot with Win 8.1 Pro:
The sound when on Win 8.1 Pro is full stereo [Finding ALL the drivers for 8.1 for this older machine is not that easy but it is doable]
Back to sound/audio - hope the details of working Win 8.1 Pro Audio drivers can help someone:

You have to ask the reporter of VGN-A790 laptop which has same pci ssid 104d:81cd as your VGN-A497XP

http://git.alsa-project.org/?p=alsa-tools.git;a=blob;f=hdajackretask/README;hb=HEAD

You need to find out whether line out node is internal speaker and which mode is your mic and internal mic

[Raymond (superquad-vortex2)]

https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/tree/sound/pci/hda/alc260_quirks.c?id=c29b3f6dd7798964d77199af4925be72a3a48349

This is a regression of removing static model of alc260, you have to file upstream bug report at bugzilla.kernel.org

[Art (aglotus)]

Thank you Raymond.
Bug has been submitted:

You have to post result of hdajacksensetest when you plug and unplug headphone jack and mic jack

The auto parser seem ignore the line out pin when default association is zero

OK Eureka: we have sound on headphones and laptop's internal speakers!!!
Thank you Raymond for all the help you gave.
As local user, launch hdajackretask:
$ hdajackretask

* Select "show unconnected pins"

* Pin 0x0f override to (dropdown menu) --> Internal Speaker

* Pin 0x10 override to (dropdown menu) --> Internal Speaker (LFE)

* Pin 0x15 override to (dropdown menu) --> Headphone

Still received message:
"tee: /sys/class/sound/hwC0D0/reconfig: Device or resource busy"
but the above seemed to have worked.

To make this permanent click button:
"Install boot override"

[P.S. was googling the "tee: /sys/class/sound/hwC0D0/reconfig: Device or resource busy" message and got inpiration from:
https://www.reddit.com/r/linux/comments/17sov5/howto_beats_audio_hp_laptop_speakers_on/

- although obviously the link deals with a different model ]

Thank you very much again.

RE microphone:
"and you need to find the mic and internal mic from 0x12, 0x13, 0x14 and 0x16"

Have set pin 0x12 as Microphone and
pin 0x13 as Internal Mic.

[Art (aglotus)]

For fix please see towards the end of comments here.
But in a nutshell, the fix consisted of:

As local user, launch hdajackretask:
$ hdajackretask

* Select "show unconnected pins"

* Pin 0x0f override to (dropdown menu) --> Internal Speaker

* Pin 0x10 override to (dropdown menu) --> Internal Speaker (LFE)

* Pin 0x15 override to (dropdown menu) --> Headphone

Still received message:
"tee: /sys/class/sound/hwC0D0/reconfig: Device or resource busy"
but the above seemed to have worked.

To make this permanent click button:
"Install boot override"

Many thanks to Raymond (superquad-vortex2) for spending time looking at this and offering potential ways to resolve this!
