Summary:                    LW20 bugs with headphone input, realtek.com.tw has a
fix, please intergrate it!
Description: 
My new laptop has a HDA Intel (Realtek ALC880) soundcard. 

It though for some reason do not turn off the main speaker when you insert
headphones. On the site
http://www.realtek.com.tw/downloads/dlhd-2.aspx?lineid=2004052&famid=2004052&series=2004061&Software=True
there is a patched alsa package available which fixes this issue by adding
a "Headphone" mixer which you can turn on/off and also gives you the
availability to mute the main speakers without (as in 1.0.10/11-rc1)
muting the headphones aswell.

Can you please intergrate this? I struggled trying to intergrate this
properly but their alsa is built on 1.0.9 and I suppose I am not the
sharpest of programers either for the job.

Greets,
  Mikael

I think you misinterpretated the bug report. 

I have just tried the 1.0.11-rc2 with the same result. 

To clarify the bug report:

 * My laptop has a set of stereo front speakers
 * It has 1 mic input and 1 lineout and 1 headphone jack
 * When inserting the headphones to either lineout or headphone jack the
front speakers will not mute
 * If you mute the "Front" bar in alsamixer both front speakers and
headphones mute
 * Realtek.com.tw has implemented a bar named "Headphone" which you can by
software mute / unmute in combination of muting only the "Front" bar,
which solves the problem.

I had submited bug #0001572 describing the same problem back in November
17, 2005.
The bug still applies to current alsa-driver 1.0.11_rc2.
I'm running the same laptop LG LW20 with gentoo linux (kernel 2.6.14).
