No sound from internal speakers after several resumes on Lenovo L450

What is the output of:

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

Thanks

Here is the output:

Note: while running alsa-info.sh the sound via laptop's speakers worked. Is it ok for you? Or do you need an output generated while the sound does not work?

I noticed one thing:
I have 2 sound cards in the laptop - alsamixer reports them as "0 HDA Intel HDMI" and "1 HDA Intel PCH".
When the issue is present and there is no sound from the internal laptop's speakers and I start alsamixer, there are these channels reported for the HDMI sound card:

S/PDIF, S/PDIF 1

After reboot, when the issue is gone, there are 3 channels for the HDMI Soundcard:

S/PDIF, S/PDIF 1, S/PDIF 2

I do not know if it is related to the issue - as I do not use HDMI or S/PDIF for sound and I just use analog output, but at least it is suspicious the channel there "disappears" when the issue is present.

Currently I face the problem and there is no sound from internal laptop speakers. I do not know if it help, but here is the current output of the alsa-info.sh script - http://www.alsa-project.org/db/?f=37a754ab19ffbbde1dd80a04692f6daff04c45df

I was lucky and I found a way of reproducing the issue. Originally I thought it is related to suspend/resume. I usually just suspend my laptop instead of powering it off. From time to time when there is a kernel upgrade, I have to reboot the laptop. And here the problem is - when I boot the PC with headphones attached, then the sound via headphones will work, but there will be no sound from internal speakers (of course when headphones are detached).

I tested this couple of time. This is the procedure A:

1. When the problem is not present, sound is present in laptop's speakers, connect the headphones
2. initiate reboot
3. once booted, initiate playing of some audio and check the sound from headphones - it will work OK
4. disconnect the headphones - there is no sound from internal speakers

Procedure B:
1. turn off the laptop (power off)
2. connect the headphones to the laptop
3. power on the laptop and boot into Ubuntu 15.04
4. once booted, initiate playing of some audio and check the sound from headphones - it will work OK
5. disconnect the headphones - there is no sound from internal speakers

So from some reason internal speakers will not work when booted to the Ubuntu 15.04 while headphones attached. Should I report this as a bug?

Hi

I know this is expired. But this is my exact same problem. It seems like the system does not recognise the unplugging of headphone jack. My system information from alsa-info.sh: http://www.alsa-project.org/db/?f=2b7caa3db4277c637f7065a411c8a9c2d9bfc46e

Is there already a bug report? Can I do something to solve this problem?

Thanks and regards

Hi Timo!
I already opened a bug - Bug #1533343 - https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1533343
But it was set to incomplete and I did not receive feedback there. You can check the bug's comments.

I have a similar issue. Dell precision 5510 delivered with Ubuntu 14.04 (sound working). Upgraded to 16.04 no sound from internal speakers but sound from headphones working. The internal speakers does no work no matter if I suspen/resume or do a cold boot.
