snd_hda_intel options database

[xtrman]

For the Conexant 5069 card I have found a way to mute the internal speakers.
Download hda-verb from ftp://ftp.suse.com/pub/people/tiwai/...erb-0.3.tar.gz.
Then execute

sudo hda-verb /dev/snd/hwC0D0 0x1f 0x701 1

to turn the internal speakers off and

sudo hda-verb /dev/snd/hwC0D0 0x1f 0x701 0

to turn them on again.

I have also filed a bug report upstream on this.

Edit: I have now created a daemon to automattically mute and unmute the internal speakers when headphones are plugged in and removed.

Compile with g++ main.cpp -o pinsensed
Run with sudo ./pinsensed

Thank you very much, that worked! The only thing, I had to compile using g++ instead of gcc. But now I can finally use my headphones without having my speakers sounding at the same time.

xtrman - you are a legend. Works for me on an Asus K52J.

I added the pinsensed command to /etc/rc.local as well so it auto-starts. I also needed to use g++ in place of gcc.

[demetrius2009]

You are the greatest man!!!!
This worked for me too on my Asus K52JR Ubuntu Lucid 32 bit

[desuid]

Its work on Lenovo G560. Many thanks!

Thank for this thread)))
Laptop: Samsung R25plus (no built-in mic)
Problem: external mic not working (no sound)
OS: Ubuntu Lucid Lynx
Sound: ALC262

Solution:
sudo gedit /etc/modprobe.d/alsa-base.conf
at the end of the file add

options snd-hda-intel model=hippo

and reboot!!!
digitall inputs work fine (with jack detection)

[diaz8]

My Sony VGN-NS21S works fine with
options snd-hda-intel model=toshiba-s06

only sound throu headset after installation.
fixed with:

options snd-hda-intel model=targa-2ch-dig
alternativ (both worked):
options snd-hda-intel model=targa-dig

Fix for no headphone. Thread: http://ubuntuforums.org/showthread.p...18#post9294918

Add alsa-base.conf option:

options snd-hda-intel model=dell-eq

[dolphinsonar]

options snd-hda-intel model=dell-bios power_save=10 power_save_controller=N

This fixed the problem with my Dell Inspiron 1318 laptop. The build in microphone (mic) was not working until I added this. Now Skype test call returns my voice using the built-in mic.
