HP DV 67xx Conexant HD audio - Interesting discovery

[Vegetarianrage]

So, along with the rest of the linux world, I'm having issues getting my computer to correctly identify the difference between the jack inputs and outputs and the internal inputs (mic) and outputs (speakers).

My problems are as follows:

Muting the speakers only applies to the internal speakers, not the headphone jack.
So for example, if I have headphones plugged in and I mute the master device output then nothing happens. Volume adjust DOES work.

Microphone input only works from the jack.
No amount of banging or shouting at the internal mic will make it register any sound. I have tried adjusting literally everything on alsamixer and in pulse. Opening pulse's recording vu meters shows no activity until I plug in an external mic.

My interesting discovery is that ALSA seems to recognize my card, and many other people's, as a CX20561 (Hermosa) instead of a CX20549 (Venice). I've looked at my drivers and at the Conexant website and I'm pretty sure I have the Venice card. I tried adding

options snd-hda-intel model=laptop-hpmicsense

to my /etc/modprobe.d/alsa-base file which according to /usr/share/doc/alsa-base/driver/ALSA-Configuration.txt.gz should force it to use the CX5045 drivers but it made no difference. In fact, I couldn't seem to force it to load anything at all. No matter which model I stick in alsa-base it always "correctly" loads the Hermosa drivers.

I know CX20549 (Venice) is the same as CX5045 because if you go here, and search for 20549: http://www.alsa-project.org/main/ind...rc2_v1.0.14rc3
you will find:

hda-codec - More fixes for Conexant HD Audio support

Renamed Conexant 5045 to CX20549 (Venice) per Conexant Documentation
Renamed Conexant 5047 to CX20551 (Waikiki) per Conexant Documentation
Fixed automute on HP Laptops with CX20551 codec.
Fixed recording issues on Toshiba Satelite P100/P105 series laptops
Added HP DV8000, DV2000Z, Fujitsu Si1520 support

More work to be done on CX20549 based systems, but CX20551 Systems are
much better now.

So, is there a way to force it to load the CX5045/CX20549 drivers in place of what it's loading now? I couldn't get it to load anything else no matter what I put into alsa-base. Even when I tried to break my sound by forcing incompatible drivers. What am I doing wrong?

Good discovery vegetarianrage. I have tried your

options snd-hda-intel model=laptop-hpmicsense

to no avail. My pastebin is at
http://pastebin.ca/1003159 . I have spent so much time on this, it's not funny. I might just get an external mike. Thanks for the detailed digging.

[Vegetarianrage]

I've already got an external mic because I have to use skype quite often. It defeats the laptop however, to have to carry hardware around with me. I can't stand it. There must be some way to force it to detect the correct hardware.

I got the same problem on my HP Pavilion dv9810. Sound is fine except for the microphone.

I have a HP Pavilion dv9000 with Conexant sound card(laptop)

For the first time everything works fine(even the wifi) but the capture part of the recorder. I have resolved to dual boot for the soul purpose of audio recording. It's not a total defeat, though. I have installed Ubuntu on my desktops in the recording room. At least there on those units there is recording capability.

But please let me know if there is a breakthrough on those drivers.

so did anyone help you get capture working?
I too have problems with any sort of capture ability.

Yours is recognized as a venice? Would you mind posting your hardware info?
This code downloads a script which checks out your setup and makes a pastebin automatically, courtesy of the people at #alsa on freenode. If you're anxious about running the script I encourage you to go question them about it.

wget http://home.cfl.rr.com/infofiles/tsalsa
bash ./tsalsa

Then paste the the url printed by tsalsa on here. I just want to see what driver versions you're using and what the id# of your audio device is. Thanks!

Here's mine: http://pastebin.com/f1b6afbac

Note, if it fails to upload your file to the pastebin service you'll have to do it manually. The text file is found at /tmp/tsalsa.txt

does that say anything to you? Don't see much about drivers there.

[cbw]

theres more.

I have the same laptop, well mines dv9225us, with the same conexant sound card, and my internal microphone worked immediately out of the box, with no change in drivers or tweaking configurations, dont know why yours wouldnt work
