[XPS 15 9550, Realtek ALC3266, Black Headphone Out, Left] No sound at all

[shinyblue]

All was working fine, then one day it goes silent when plugging in my speakers to the headphone socket, and forever after with something plugged in (internal speakers still work fine).

Looking at pavucontrol and/or "Sound settings" under Gnome it shows that the sound should be playing on the Headphones output port - the VU meter is bouncing up and down ok, but it's silent. Pull out the wire (or select internal speakers for the Output) and the sound switches to the internal speakers OK.

Last time this happened I fiddled for ages and then got distorted sound (sounds like some sort of cross-channel thing) and this only went a away with a complete re-install of Ubuntu (which I did to try to fix a separate bug but am not willing to do again!).

I ran alsa-info.sh from the command line and uploaded the info. Here's the URL it gave me to share: http://www.alsa-project.org/db/?f=06...3f7ebb379442a7

It's now happened again, having spent all Friday enjoying music, Monday morning turn on and silence! I've not done any upgrades since.

I have tried completely reinstalling pulseaudio (based on suggestions found on the ubuntu wiki) to no avail.

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

Related with bug #1575078 ? or the same?

[Cruz Fernandez (cruz-fernandez)]

Have you tried to suspend and resume the laptop? I've got the same laptop and that kind of things bring back the sound.

Seems same as #1575078 to me.
