Ehm...
I don't understand. Are you saying that my laptop is "doing the wrong thing" and should be playing out through the built-in speakers as well as headphones when jacked in?
Also, the issue here isn't that I (or other, run-of-the-mill users) *want* both outputs to play. I'm asking for the more common behaviour where the speaker output was muted when headphones were plugged in.
If you're answering my question, I just don't understand you ): Please explain again?

Good day
I'm new to this list (though I've done some searching, I'm sure I could have missed something), so please bear with me.
I filed a bug report recently against Ubuntu with respect to the problem I'm experiencing (as per the subject: jacking in my headphones doesn't mute
the
speaker output) and was informed that the decision had been made upstream as a design intention. I was linked off to:
http://mailman.alsa-project.org/pipermail/alsa-devel/2010-August/030071.html
with respect to the thread on this topic. I'd like to raise it again though, perhaps as a configurable feature, for the following reasons:
Enable auto-muting in model=auto only for devices with HP and speakers.
http://git.alsa-project.org/?p=alsa-kernel.git;a=commitdiff;h=2a2ed0dfc9ec44...
if the bios set your laptop 's speaker as line out , you need to implement a new model for your laptop ,
model=auto assume the bios had already correctly setup all the pin complex of your computer
- headphones muting the speakers used to work some time ago (before
Ubuntu
9.04, iirc), so we have an established user expectation even under Linux distros. 2) headphones mute the built-in speakers of my laptop (windows and
ubuntu)
-- why the inconsistent behaviour for a desktop? Just because the
speakers
in the laptop are bolted into the frame of the machine? 3) Windows "gets it right": plugging in headphones mutes external
speakers
-- it's convenient (Though I think you can disable that feature if you want). I'm told by a person at work that his Mac does the same. Again,
the
user expectation is unmet under a newish Linux distro. 4) The user expectation theory is held up by the number of bug reports against this design choice on Ubuntu Launchpad alone (I haven't looked at other bug lists). The average user is not expecting the current
behaviour,
obviously 5) For people without hardware volume controls on their speakers, the problem is exacerbated: instead of being able to plug in headphones to disturb others around them less (ie: contain their music/noises), they
have
to unplug their speakers too -- which may not be trivial since speakers
are
normally plugged in at the back of the machine, not at the front where
the
headphone jack would be found. On a machine in an enclosure, this is especially troublesome.
So I'd really like to know if it would be possible to allow the behaviour most users are expecting. Sometimes it's useful to be able to output to both speakers and headphones, but I would say that the average user doesn't
want
both at the same time.
