Diff file from HDA Analyzer
After using HDA-Analyzer, and adjusting Node[0x1c] PIN, initial settings show that EAPD is not set. Checking the EAPD option allows sound to be heard, although it is very very low, with all the mixer settings maxed out on any media (audacious,xmms,mplayer, youtube stream).
Did you find a solution? I'm having K40IJ as well. tried many of the solutions on the web, none worked. btw, how did you set the EAPD option?
Well I kinda forgot about this bug report to be honest but i gotten the sound to work. I downloaded and install the latest alsa driver. and then i used hda-verb to enable the EAPD automatically on startup.
here's how to do it.
--- commands start here ---
tar xf hda-verb-0.3.tar.gz
cp hda-verb /usr/bin
--- command ends ---
then add this line into /etc/rc.d/rc.local by doing
sudo nano /etc/rc.d/rc.local
and insert the following line:
hda-verb /dev/snd/hwC0D0 0x1c SET_EAPD_BTLENABLE PCM
Since i'm not familiar the updating of alsa driver, i tried the rest of your instruction. didn't work, but noticed some errors:
1. i dont have the rc.local directory in my system. so i created one (with sudo)
2. the /dev/snd/hwC0D0 didn't exist (only PCMC0D0c, PCMC0D0p)
could it be because i'm using ubuntu (9.04)?
not urgent, reply in your spare time. thank you again.
I will have to see how the directory structure of ubuntu to help you further. give me a couple of days(maybe more) while i try and work something out. i do have a spare HDD to install ubuntu into the K40IJ (maybe).
alternatively you could try the steps shown here http://alsa-project.org/main/index.php/Matrix:Module-hda-intel for upgrading the alsa-drivers
another link i found was from http://ubuntuforums.org/showthread.php?p=6589810#post6589810 a script which allows users to update the alsa packages.
as well as https://bugs.launchpad.net/ubuntu/+source/linux/+bug/393523 which uses the same technique to force the EAPD flag to be toggled on bootup.
i'm almost certain that the /dev/snd/hwC0D0 directory exists across all distributions assuming that the alsa-drivers are updated.
let me know what happens.
This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '11'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 11's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 11 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
