Subject: Headphone output doesn't work with 3.0.0-rc* anymore
Hi,
before 3.0.0-rc1, when I plugged anything into headphone output of my
laptop, speakers were disabled and the sound has been routed to the
headphone output. This doesn't seem to work anymore starting with
3.0.0-rc1. Speakers stay on even if I plug something to the headphone
output.
Is this a bug or a new behavior that userspace has to cope
with?
I am sorry for the lack of information but I have no idea what to
provide. Let's add dmesg and config at least.
Btw. I have noticed the following message which might be related:
input: HDA Intel Headphone as /devices/pci0000:00/0000:00:1b.0/sound/card0/input11
I do not see anything like this in .39 kernel.
I am using Intel HDA integrated soundcard:
