Headphones wont functions Mint 10 Julia

[bolter40k]

I am running linux mint 10 64 bit amd on a gateway nv52. When I plug headphones into the jack, audio output does not switch. I feel like I'm missing a simple setting somewhere. Sound works normally otherwise. If anyone can offer me assistance it would be greatly appreciated.

Thanks,

Hi bolter40k. Try opening the Terminal. Type:

Code: Select all

alsamixer

Make sure none of the indicators are muted, particularly for headphones.

All of my levels were unmuted in alsa when i opened it in terminal

for some reason if my headphones are plugged in while my laptop is booting they work but my problem still exists otherwise.

First off, find out which codec is used, I suspect that the module loaded is snd_hda_intel, to find out which codec it uses start alsamixer and it will display the used codec in the upper left corner(it says "chip")

Code: Select all

william@Ra ~ $ alsamixer

If the used card is "HDA Intel" you will need to open the alsa-base.conf file

Code: Select all

william@Ra ~ $ sudo nano /etc/modprobe.d/alsa-base.conf 

Then at the very bottom of this file you add the following line(replace "fujitsu" with an appropriate model for your chipset/codec found in the HD-Audio-Models.txt.gz file, command to view it shown below), save with ctrl+x and reboot, this process most likely is trial and error, trying out different models until you find one that works for you.

Code: Select all

options snd-hda-intel model=fujitsu

Models for the chipsets/codec used can be found by typing this in a terminal:

Code: Select all

william@Ra ~ $ zcat /usr/share/doc/alsa-base/driver/HD-Audio-Models.txt.gz | more

Do please share your success if any, detailing what steps you took to solve the problem and add [SOLVED] to the topic
If this doesn't solve the problem, continue your quest and keep asking, provide any information you can.

the used card is hda ati sb not intel. Do i still have to open the config file?

Type the following in terminal and post the output here, they will list which codec is used, at the bottom of this post I'll include the output of "cat /proc/asound/card0/codec#* | grep Codec" on my system

Code: Select all

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

and

Code: Select all

lsmod | grep hda

If the last one of these list a module called "snd_hda_intel" then my advice in the earlier post still holds valid...

My codecs, modem listed first and soundcard last:

Code: Select all

william@Ra ~ $ cat /proc/asound/card0/codec#* | grep Codec
Codec: Motorola Si3054
Codec: Realtek ALC880

here is the output of the commmands ran in terminal,

I see the snd_hda_intel module loaded there but the conexant codec can't be found in the HD-Audio-Models file which for the moment leaves me stumped...
I googled "alsa conexant cx20561" and found lots of stories similar to yours, but this page might be of interest to you though: http://www.linuxant.com/alsa-driver/

[EDIT]
A closer look at the above link suggests that it's probably meant for those that have conexant chipset based modems...
Still, go through the HD-Audio-Models file and try with different models and see if jack-sense will work, tedious trial and error but it might work...
