Even my codec info changed from conexant id 5059 to CX20585

Code:

$cat /proc/asound/card0/codec#* | grep Codec

I cannot find anything relevant in

Open this file for editing:

Code:

 gksudo gedit /etc/modprobe.d/alsa-base.conf

Insert these lines at the bottom:

Code:

options snd_hda_intel model=laptop
options snd-hda-intel position_fix=1 enable=yes

Save. Close. Reboot. Check your levels in alsamixer.

Code:

 alsamixer

Press <F6> to select the correct soundcard.
Press <F3> to show playback levels. <F4> selects capture levels [or use <Tab>]
Use the left/right arrow keys to select and up/down arrow keys to change levels. <M> to mute/unmute.
Go to "System ->Preferences ->Sound" and make sure the correct soundcard is default.

Earlier ,I used to hear audio from both the internal speakers and the headphones. Now it doesn't play through the headphones even if they are connected.
i.e its not detecting my headphones after upgrading alsa!

(if i try to change the output device in system->preferences->sound from 'Internal Audio Analog Stereo' to 'High Definition Audio Controller Digital Stereo(HDMI)' )

I attached my alsa-base configuration file.
Can you please elaborate what do sound levels for 'S/PDIF' represent? they were muted when i tried to run alsamixer .I can only unmute/mute them but none of them seem to send output to my headphones.

The analog card is the one you would use for headphones, not digital(spdif). If those options are not working try changing the model to lenovo. Then try only one line at a time. You'll need to reboot each time for the changes to take effect.

SOLVED!
After 9 painful days of searching and installing needless stuff ...it's funny when you overlook the obvious(googling for the necessary audio driver) from the simple(googling endless forums to add a line in the alsa configuration file). For all conexant audio chip problems ,I guess here is the solution :

http://www.linuxant.com/alsa-driver/

download the .deb package from
http://www.linuxant.com/alsa-driver/....0_all.deb.zip

unzip it

Code:

unzip alsa-driver-linuxant_1.0.23.0_all.deb.zip

run it ! (enter password when prompted)

Code:

 sudo dpkg -i  alsa-driver-linuxant_1.0.23.0_all.deb

Everything works perfectly on my laptop now.

If you have a similar problem of not finding the correct option to put in that alsa conf file, i suggest you google for the appropriate linux drivers first.

The conexant codecs have definitely been a problem. Thanks for that pointer saiganeshb!
