Title:
Volume bug when connecting headphones to jack
Status in pulseaudio package in Ubuntu:
Incomplete
Bug description:
On Ubuntu 12.04 up to date (1 march). When i (for example) set my
system volume to max and then connect my headphones (but not plugging
the jack to the end of jack port) - the volume on headphones is set on
max too (it deosn't even see the headphones connected as an output
sound device). But after fully putting jack to the end of jack port in
my laptop - the sound is set to my previous headphones setting and
headphones are recognized as a sound output correctly (in sound
settings).
I'm not sure if it's pulseaudio's fault. I think it's a dangerous bug
cause of potential damage to ears. Of course people would rather plug
the jack correctly and not partly like i did, but still it'd be a
moment of max volume on headphones for them either way while plugging
the jack in.
On Windows 7 - on the same hardware there's no issue like that. When i
plug jack only partly like before on Ubuntu - the sound is set to
previous headphones setup immediately without loud volume, even if
system volume is set to max. So i assume it's possible to fix this for
Ubuntu :)
