headphones do not mute speakers
felmon davis
I have a sudden problem in Kubuntu 7.04 using hp pavillion dv2000 and alsa
drivers.
plugging in the headphones does not mute the speakers.
this used to work fine until a day or so ago. I cannot connect it with any
changes I have made but who knows?
I have tried fooling with kmix and alsamixer but so far, nothing works.
the problem is systemic, thus it makes no difference if I use kaffeine,
mplayer, etc.
the problem does not occur in Windows Vista on the same machine.
I have am googling but so far, no good.
any clues?

This behaviour you are talking about has been the same for me since I
installed Ubuntu. I have to turn down my speakers while listening out the
front output jack. In Vista, from what I remember of it has a new way of
dealing with sound devices, which work in the way you describe, choosing a
device disables the other.
I actually prefer the Ubuntu way as I don't have to go to a control panel
or mixer to change between headphones and speakers, so I haven't looked
for a solution. So in short, the behaviour you are seeing, I believe is
normal.. can you not just switch off your speakers when you don't need
them? Sorry I couldn't be more help.

I am sure this behavior was otherwise when I installed Kubuntu, viz. the
speakers went off when the headphones went in.
so I think something has changed presumably because of some configuration
alteration I inadvertently made or some update.

no, unfortunately I haven't found a way to shut off the speakers. I would
be a bit less perturbed if I could though I do prefer that they turn off
automatically.

I think I should clarify my response briefly: so far any way I have found
to turn off the speakers also turns off sound to the headphones on the
laptop (hp pavillion dv2000).
there is the 'kmix' utility and also 'alsamixer' but I haven't found a
setting which kills the speakers and leaves the headphones alone.
the 'kmix' utility looks rather meagre to me. the same utility in OpenSuse
has a lot more options for setting sound. perhaps there is some way for me
to upgrade the mixer or get a better one?

OK. But I have to ask.. Are you turning down a volume dial on the
speakers themselves (like I do) or are you adjusting the volume in
(k)ubuntu? If its from software, then your experience is correct.

I use Ubuntu, in it, if I go to System, Preferences, Sound (there must be
a similar option in KDE) there is a preferences dialogue, on it there is
DEVICES tab and at the bottom there are choices.. PCM, FRONT, FRONT MIC,
etc and I *can* individually adjust the sound properties for each output
there..
Good luck!

there is a volume control on the laptop itself. changing it changes
both the speakers and the headphones, unfortunately.

yes, I'm talking about my kubuntu 7.04 system.

ah, I see: you are using gnome?
unfortunately (again), there is no such setting here in KDE. there is a
sound setup utility under 'system' but it provides no finer control over
devices than selecting the driver (alsa in my case) and a few other
factors not pertinent to my problem.

it's a bit frustrating. maybe I will try reinstalling the driver.

A temporary fix that might get you through:
Type alsamixer in terminal.
Left and right key selects devices.
Use the m key to mute and unmute devices.
In the event that reinstalling your driver doesn't work, here are a few
links that might at least send you in the right direction:

naw, already been doing that blue in the face.
I just downloaded and recompiled the alsa-driver but that's made no
difference.
I am working through the references you gave below - very grateful for
that - and one of them so far, the 3rd one, looks promising - the first
two made no difference - but is rather complex and branches into other
urls in addition. I shall look more closely when I get a second wind.

I probably won't look much further tonight but perhaps dig in tomorrow.
thanks, Little Girl!

well, I am not sure what happened, I can only guess.
I compiled and installed new alsa drivers and fiddled with the alsa-base
config file, but no go.
I followed a tip in one of the links you provided where a person rebooted
with the headphones plugged in. when I did that, it worked!
and now I don't need to have the headphones plugged in at boot. I get
sound from the speakers with headphones unplugged but the speakers go mute
when the headphones are plugged in. that is what I wanted.
here is my guess: probably (!) rebooting after the driver install put in
the fix. (perhaps just restarting X would have sufficed, I cannot tell.)
anyway, I am relieved. thank you for those tips!

Heh, I saw that one. I wonder *why* that works. (:

I'm so glad it's working now!

Maybe one of our local gurus knows this one. I think kernel updates are
the only things one has to reboot for. I don't enjoy rebooting, so when
I'm unsure, I log out and back in and if whatever I changed works, I
stop there.

You're welcome, but I think reinstalling the driver was the fix. (:
