speakers audio won't work - pavucontrol is switching continually between speakers and headphones

[Alessandro Ignis]

The port is continually switching between Speakers and Heaphones and no audio is outputting from the speakers. I have tried various distributions and have found that this problems is NOT present in Ubuntu 11.04, 12.04, 13.04. I have not tried 11.10, or 12.10. But have found 13.10 and 14.04 to show this identical problem.
My main concern is for the 14.04 LTS version I am currently using.

- I tried regulating the audio from alsamixer -by disabling auto-mute in alsamixer i managed to stop it switching from one port to the other. Still, no audio from speakers (only a regular and low-volume BUMP comes out)
- I tried modifying the /etc/modprobe.d/alsa-base.conf file. Since i could not find my pc (Packard Bell EasyNote MX45) in the alsa-configuration list, i have tried using only the audio boards main info as referral (Intel HDA AD1986A NM10/ICH7). Thus i have added to the alsa-base.conf the following and rebooted after trying each and every new line (added only once per try, not all of them together).
                  -options snd-hda-intel model=laptop
                  -options snd-hda-intel model=laptop-eapd
                  -options snd-hda-intel model=3stack
                  -options snd-hda-intel model=generic

- Also tried the position_fix quirking suggested on the ubuntu documentation pages
                 -options snd-hda-intel position_fix= 1
                 -options snd-hda-intel position_fix= 2

The audio outputted from the speakers kept being a regular BUMP and nothing more, regardless of the input.

Status changed to 'Confirmed' because the bug affects multiple users.

[Kristof S. (ksa1)]

I am also affected by this bug, using 14.04 LTS.

Hardware:
Asus Pro52H Notebook
Sound-Chip is as described above: Intel HDA, AD1986A NM10/ICH7

The symptom is also as described above:
In the alsamixer the port is continually switching between Speakers and Headphones.
In result on the desktop you can see a constantly "blinking" volume display.

This happens just with the basic installation (auto detection), so the default installation already leads to the bug.

In can confirm that the bug is related to the auto mute feature, it only happens when auto mute is enabled. On the other hand having it disabled, I got no sound at all (though at least no blinking volume display on the screen).

Currently I am using this setting in alsa-base.conf:

options snd-hda-intel model=laptop-eapd position_fix=1

With this at least I got the headphones working and the blinking volume display does not appear any more.
As said, speaker not working, already the speaker port is said to be "not available" in the sound control.

Using that manual option last year I already had a fully working sound in an earlier release, I think it was 13.04, though I am not 100% sure.

[Kristof S. (ksa1)]

Is there any bugfix or workaround?
Can I install new alsa packages with included fix or something like that?
Thanks in advance!

[Alessandro Ignis (artaeun)]

i didn't manage to find any workaround till now. Only thing i could do is keep the 12.04 version. Cheers

your system log have lots of

[Alessandro Ignis (artaeun)]

I actually have a hardware switch for wifi connection, but i don't remember if at the time of the test i used LAN for connecting to the net or not. Though i am sure the bug manifested itself even when the wifi connection enabled.

[Kristof S. (ksa1)]

Should I post some debug output for the Asus Pro52H Notebook, too? In case that would help: Which logs do you want?

you have to post output of alsa-info.sh

seem pro52h not in the above asus notebooks which use ad1986a

post the pulseaudio verbose log and find out whether the hp jack is plugged and unplugged rapidly

try to find out the jack state is inverted or not by hda-jack-sense-test

https://bugzilla.kernel.org/show_bug.cgi?id=66621#c41

you can also try the modified version which can measure impedance since pincap supoort ImpSense

...and pulse audio verbose log, too... (attached gz-file)

First automute was deactived, then I activated it - the volume bar started to freak out - and I deactivated it again. Well, it is a lot of log output and I hope the important information is easy enough to find there...

Many thanks in advance, it would be really great if that sound bug could be fixed!

[Raymond (superquad-vortex2)]

do pulseaudio log complain about the mic jack ?

 the model which you select set bit 8 of pin default of node 0x1f

try

hda-jack-sense-test -a

when you plugged and unplugged mic jack
to find whether your mic jack support jack detection

[Kristof S. (ksa1)]

Do you mean a physically connected microphone? I never used one with this Notebook...
I did not find a command/script 'hda-jack-sense-test'...

When I connect ear phones the connection is noticed by the desktop environment, so it seems there is some jack detection at least for the phones.

[Raymond (superquad-vortex2)]

your asus pro52 seem not set pin default of internal mic

can you post the output of alsa-info.sh when not specify any model ?

the headphone remain unplugged in your log

you have to file an upstream bug report since your case seem different from mx45

[Kristof S. (ksa1)]

Ok, here is alsa-info.sh >>without specified<< model, so it should be just "installation default"...

The auto mute feature is disabled, when enabled the blinking volume bar bug appears as in the already described case with specified settings (the settings that worked for me in an earlier ubuntu version).

[Kristof S. (ksa1)]

Oh, to answer your question to the head phone: I did not connect it during the time generating the log, sorry for that misunderstanding. I just mentioned that the head phones work and there is a reaction when plugging in, that is not included in the log though - my main problem is that the internal speakers are not working.
(head phones do work with the above manual settings, though sometimes problems occur when you plug them in or out... Did not analyze that behaviour in detail)

[Raymond (superquad-vortex2)]

since both easynote mx45 and easynote mx65 have same pci ssid Subsystem: 1631:c022

https://bugzilla.kernel.org/attachment.cgi?id=159851&action=diff

the patch in kernel bugzilla affect both notebook

[Kristof S. (ksa1)]

How could I test if the patch is working? Are there already new package builds with the fix included that I can install...?
I already tried to use the alsa-setup.sh script (http://www.stchman.com/alsa_update.html) but it did not help unfortunately...

Still with enabled automute feature the volume bar is blinking and no sound from the speakers :-/

Tested with a few different settings in alsa-base.conf, just default without any settings , the earlier working "model=laptop-eapd position_fix=1" and with model=3stack but nothing changes...

[Kristof S. (ksa1)]

FYI: I tested again with a current Ubuntu Installation, Lubuntu 15.04, Kernel 3.19.0-21-generic #21-Ubuntu SMP (same Asus Notebook as noted above). The good news is the "switching bug" disappeared. The bad thing is that there is still no (speaker) sound yet, not with the installation default and not with manually trying the entry working for me in an earlier ubuntu version - options snd-hda-intel model=laptop-eapd position_fix=1).

Here is a recent alsa-info: ALSA information is located at http://www.alsa-project.org/db/?f=dd668e30fbdc329986902f48d7aa9229a17281e6
