Priority: medium
Bug ID: 55438
CC: [email protected]
Assignee: [email protected]
Summary: channels aren't separated after switching between
speakers and headphone (sometimes)
QA Contact: [email protected]
Severity: major
Classification: Unclassified
OS: Linux (All)
Reporter: [email protected]
Hardware: x86-64 (AMD64)
Status: NEW
Version: unspecified
Component: core
Product: PulseAudio
Symptoms:
-music sounds strange
-playing front-left (gnome) is also heard on the right headphone speaker and
the other way around
Reproduction (speakers are connected, also the headphone):
1. plug out headphones, the sound should be hearable from the speakers
2. listen to music some time
3. plug in headphones
Now this problem appears sometimes (with the headphone, the speakers still
operate fine). The problem can't be solved by restarting pulseaudio.
The weirdest thing is that the problem disappears after a while.
Sorry that I don't have more information. I hope you can reproduce the problem.
my conclusion:
It seems as if the left and the right channel are mixed to a distorted mono
sound.
But this seems only to happen in headphones. Most probably it is a fault in the
headphone detection (the headphone itself is new and works fine) or a hardware
problem (broken driver?)
Technical data:
pulseaudio: git, build date: 22.9.2012
distro: archlinux
mainboard: GA-MA785GT-UD3H
