Codec: Conexant CX20590 - Mixer: Intel CougarPoint HDMI - card 0: PCH [HDA Intel PCH], device 0: CONEXANT Analog [CONEXANT Analog] - headphones/microphone are not working but the internal speakers are working on Dell System Inspiron N411Z in Ubuntu 11.04

Asked by farinaldo da silva queiroz

I have a dell inspiron 14z , ubuntu 11.04 Natty 32 bits. When I play a music/movie I can hear it only through the internal speakers, but I cannot hear it through the headphones. And also my microphone is not working. I also have windows 7 installed but there everything works ok. I had the same problem before and with you help I could solve it typing:

sudo add-apt-repository ppa:ricotz/unstable; sudo apt-get update; sudo apt-get install linux-sound-base alsa-base alsa-utils gdm ubuntu-desktop linux-image-`uname -r` libasound2; sudo apt-get --reinstall install linux-sound-base alsa-base alsa-utils gdm ubuntu-desktop linux-image-`uname -r` libasound2; killall pulseaudio; rm -r ~/.pulse*

But now, It doesn`t solve for some reason. Thanks a lot guy for the help It`s been a while that I`m trying to solve this.

Here it is my ALSA information:

try adding:

options snd-hda-intel position_fix=1

to /etc/modprobe.d/alsa-base.conf

See if it helps

It`s dumb question but could you tell me how to add this in the alsa-base.conf ? I`m trying to write something in it but it is protected.

run:

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

and it will be writable.

Please try Derek's solution at the end of the following thread:

https://answers.launchpad.net/ubuntu/+source/alsa-driver/+question/168960

I quote:

"A temporary solution has been found:

1) Terminal Code:

sudo add-apt-repository ppa:ubuntu-audio-dev/ppa
sudo apt-get update
sudo apt-get install linux-alsa-driver-modules-$(uname -r)

2) Restart computer

Audio controls are now available for me in alsa and pulse audio interfaces. Headphones work without noise from the speaker, and then internal mic picks up sound. (Please note: internal mic works, but is very quiet with large amounts of static. It is not practically unusable, so it is still a problem)

Please note that this method worked for me BOTH with AND without:
options snd-hda-intel model=vaio enable=1 index=0 position_fix=1
inside file gksudo gedit /etc/modprobe.d/alsa-base.conf

I don't know if other fixes provided by actionparsnip had any effect on the eventual outcome.

Closing problem for now (as mic static is probably a different problem). Thank you for your assistance!

Hi guys I tried both possible methods above. The good one was the solution provided by actionparsnip. It made my headphones starting working, however I still cannot hear only through the headphones. Thanks for the help guys.
