sound in Ubuntu 9.10

[zongo saiba]

Hi all, 

Sound is actually giving huge grief in ubuntu 9.10. 
Main issue with Toshiba Satellite T110: 
When I connect my external headset to jack, the internal speakers are
not muted. I  know this has been already discussed and obviously their
seems to be no fix at all. As far as I have noted on Google, this bug
has been around for quite a while. May I add that I have no issue with
sound whatsoever. As much as it is not a system threatening bug, It is
one of the most annoying one. Especially when I take my netbook with me
in the train and want to listen to some music or even watch a movie.. 

uname -r --> 2.6.31-20-generic
Unit: Toshiba Satellite T110

Troubleshooting:

- blacklist pcspkr
# headset connected to jack
options snd-hda-intel model=auto
# mute internal speakers when jack connected
options snd-hda-intel position_fix=1 model=auto (lenovo)
# options snd-hda-intel model=laptotp

Internal speakers still do not mute when headphones are plugged in
though.
options snd-hda-intel model=3stack does the same at "model=auto", as
does
options snd-hda-intel position_fix=1 model=auto

cat /proc/asound/card0/codec#* | grep Codec
Codec: Conexant CX20582 (Pebble)
Codec: Intel G45 DEVCTG

I have the latest in alsa drivers and pulse. I have added "asoundconf"
to have the opportunity to chose between my internal audio card or pulse
audio. All this to no avail. 

Unfortunately I cannot go further than what I have done. The reason is,
my knowledge of linux is very much limited. I am merely a newbie trying
to make his way through. 

Would it be that hard to fix that annoying bug ? 

To end this discussion, if technically, someone can explain to me that
it is not possible to fix that bug, then I am ok with that; but I have a
feeling that it is just a matter of putting some hours into developing
good drivers (Am I wrong ??). With all the infrastructure Ubuntu has, it
should not be an issue. I mean, that is exactly what's wrong with linux.
They started with OSS drivers (from what i gather they are still
maintained), then drifted to alsa and pulse audio.; Why not stick with
something and try to bring it to perfection so people will actually
enjoy using Linux and not banging their head with such small matter but
hugely annoying. 

Could anyone tell if this issue has been fix in the latest release of
Ubuntu ?

PS: I know that plugging a usb headset would sort my issue here. I have
a plantronics headset but they are huge. I have a netbook and I want
mobility most of all. I just bought these new headsets for mobility..If
I only knew.. I shelled out 80 £ for them..Very frustrating..


Thank you guys for your help.
