**************************************************************

Hello,

I have an HP Pavillion TX2000z. This laptop has uses the snd-hda-intel and has the ALC861VD realtek codec. The existing configuration for the codec does not support the tx2000 series laptops fully.

There are several configurations that have various levels of support.

If you specify for the model to use the existing hp model (made for the tx1000 series) then:

1.Headphones Work 2.Speakers Work 3.Front Mic Works (the jack mic by the headphone jack) 4.The External Mics do not work (There are two mics at the top of the laptop... I am guessing left and right for a stereo Mic) 5.It seems like there is something mapped to an input that does not belong there. The simplest way to explain this is when I open audacity and set it to monitor input that there is significant white noise coming in. The Ext. Mics are not working so it can't come from there (as far as I know) and I have nothing plugged into the front Mic. I cannot find any way to mute this noise.

When using the 3-stack model (with the option position_fix): 1. Headphones do not work (in either ports) 2. Speakers Work 3. Front Mic Works 4. The external mics work 5. Same problem as expressed above

All other models do not work in any significant way.

Also one of the Headphone ports (there are two on the front) has Digital Out (optical) that I have no way of confirming if it works.

Now, that being said, I have tried working on the driver. I have virtually no programing experience. I was able to have the driver autodetect the soundcard and apply a certain model (before it had to be applied with a module config file.) And was able to interpret some of how the driver worked. But I am so lost. I am not sure how hard it would be for a programmer to modify the driver to support the tx2000.

So I want to put out a call to anyone who could help. I am fully available for testing and some debugging if someone could try and help. I am uploading the codec file and the codec schematic ( I don't think this is actually accurate, but It may help...)

Also here is the lspci -nn for the soundcard and other info I found

00:10.1 Audio device [0403]: nVidia Corporation MCP51 High Definition Audio [10de:026c] (rev a2)

If anyone could help or use additional information I would appreciate it. Thanks, Kory
