Guys, seriously, no one willing to help with a completely broken setup?!
It works fine on Windows, so I would really like to get it working on Linux, too.
Well, if it used to work, it's basically a regression, and at best, try to downgrade kernel or whatever to identify at which point it started regression. It'd be a great help alone to analyze what went wrong.
I do not think this is a regression. I have just double checked this with a live USB using Ubuntu 16.04 LTS. The same problem happens. The sound goes off within a couple of seconds.
sudo hda-verb /dev/snd/hwC0D0 0x1f SET_POWER_STATE 0
would bring the node back for less a minute, but that is also not acceptable.
So, basically, I would like it to work the same way it does on Windows if possible. Windows does not switch it off. It could be because they utilise the internal chip better and for other reasons, etc. At the end of the day, I would be even happier to persistently tell the node to stay up, no matter what. It may damage the internal speaker, but it is still better that I can use it for a while than I cannot use it for any amount of time at all. So, is there a way to achieve that bruteforce approach?
The nicer solution would surely be to figure out why Windows can cope with the same hardware. I do not think Windows would break the hardware.

I am sorry about flooding with my emails. I just thought that I would amend some information that I forgot to mention in my original email.
The same laptop and internal speaker work ok on Windows 10. Also, the setup used to work about 1-2 months ago. I cannot remember what exactly broke, perhaps a system upgrade. If it matters, I am using Archlinux.

Dear Alsa Developers,
My internal speaker in the Lenovo Thinkpad T510 laptop stopped
working.
Normally, it would provide either no sound or just for a couple of
seconds
and then it would go off.
I do not have auto-mute enabled. I checked it with alsamixer that it
is
disabled.
My ALSA information is located at http://www.alsa-project.org/db /?f=87547de5ff55e44e360aa2382d4e5d3b7bbed091
Do you know how I could fix this?
