Title:
[XPS 15 9550, Realtek ALC3266, Black Headphone Out, Left] No sound at
all
Status in alsa-driver package in Ubuntu:
Confirmed
Bug description:
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.
