the original automatic bug report to ubuntu launchpad

After an update my HDMI sound stopped working.

I filed an (automatic) bug report on ubuntu launchpad:
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1458136

After a while they re-directed me to the author of a certain patch (mr Takashi Iwai of alsa-project.org
He then told me to file the bug here.

I'm attaching the original automatic bug report
I'm attaching pulseaudio log

Please try a new kernel with drm.debug=14 module parameter set, and attach the dmesg.

I see that the Status remains at NEEDINFO.
Do you need any additional information ?

Comment 7 michel.verbist 2015-06-15 19:56:34 UTC

Well, to be honest, I don't know if I have that patch.

I couldn't find in the patch mail message in which kernel it was included.
I only found references to 4.2 and 4.1

I have this kernel:
$ uname -a
Linux poseidon 3.19.0-20-generic #20-Ubuntu SMP Fri May 29 10:10:47 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux


I decided to update, and see what the result was.
Apparently, sound started working again for all users, except for myself.
That's why I didn't notice it right away, that the sound worked again.
In my user account it didn't work. 
And I even had no sound device to choose from in the sound setting dialog box.
After some googling, I decided to try this, and it worked:
$ rm -r ~/.config/pulse/*
And then i copied the pulse config from a user where the sound did work.
Rebooted...
And my sound works again.

Thanks for everything.
