HP dv6000 Mic

[sananth]

My wife thanks you, and so do I. I swear, I was pulling my hair out over this one. Your solution was quick and painless. Thanks again.

EDIT: After reboot it resets itself. Do you know of any way to make the settings stick?

Glad I could help! I already lost a lot of hair to this one!

My settings seem to stick ... not really sure why you are not able to see this. I will check my alsa config and let you know if there is some way to make it permanent for you too.

BTW, which version of ALSA are you running? I am on 1.0.18.

here is the output I get, am I doing something wrong?

I#m on ubuntu jaunty 64 bit

I get the same errors as above post in jaunty 32bit..

[tim183]

I'm definately not an expert but i believe it's something to do with the errors currently in python in Jaunty

[sananth]

tim183, how did you install alsa? Was it from source or was it just the regular installation? I would recommend installing from this thread:
http://ubuntuforums.org/showthread.p...10#post6589810

I think this should help with the executing the python script. Also do
ls -l /dev/snd/controlC*
ls -l /dev/snd/hwdepC*D*

and check if you have those devices. My guess is that you will not see them if you did not use the alsa script.

Dawei87, I am running 8.10 64-bit on my machine, but I can try 9.04 32-bit through live cd/usb and let you know what I get.

spcwingo, I was able to make the settings stick by writing a python script that made use of hda_codec.py and hda_codec.pyc which are files downloaded when you run hda analyzer. I am attaching the required files here. Simply download them, and throw them into /etc/init.d/. Once you do so, make test_hda.py executable like this:

sudo chmod +x ./test_hda.py

Then, run the following command to kick off test_hda.py every time you boot up:

sudo update-rc.d test_hda.py defaults

WARNING: test_hda.py was only designed to work for the HP laptop DV6748. For other laptops, please find your card number (0,1,2 etc.), codec number (0,1,2,3, etc), mic node number from hda analyzer as an INTEGER (hda analyzer shows the node's hex number which you will need to convert to an integer) and also the row number for the pin you want to switch your default to (0,1,2 etc.). Feel free to edit test_hda.py to add all this information, and then try running it as root to see if the desired effect is achieved. This code should only be used to make your settings stick if you got your mic working using hda analyzer from alsa-project.org.

tim183, I was able to see this from the Jaunty live cd. Did you try to install alsa using the scripts mentioned on the forum link I sent you? If not, please try it out and let me know whether that helps.

In the meantime, I am going to look into hda analyzer and figure out why this is happening. I will keep you posted.

[tim183]

Sananth, ok, I will try today

thanks

[spcwingo]

Sorry I'm just now getting back to you. Just thought I would let you know, sananth, you're my new hero. That worked like a charm on this dv6707us. The wifey says thanks too.
