Acer 4830T TimelineX No Audio on Ubuntu / Mint

If you are trying to run Mint 11 or Ubuntu 11.04 on an Acer Aspire 4830T TimelineX Laptop, then you’ll no doubt notice the lack of audio from the internal speakers. Luckily, fixing the issue is painless.

Simply go to a terminal and run the following commands, one after the other:

wget -O
sudo python

The first command will download a small python script from the ALSA Project, and the second command will run said script. This script actually downloads the latest copy of the tool that you need to get your sound working. (So be sure to stay connected to the internet.)

You’ll get a nice GUI, in which you should first clickNode[0x1b] PIN“. Then, under EAPD, click the box next to EAPD. Go ahead and exit the application by clicking the “x” in the top right corner.

You’ll then be asked if you wish to revert settings. Simply click “no”.

Almost done, just go ahead and reboot your machine. You should then be able to enjoy audio from your internal speakers.

    This works for my timeline, but when i restart my computer all settings are gone. I have to download the hdaanalyzer again and put the EAPD setting on.
    Do you have any idea what i can do to save the preferences permanent?

    Thanks!! It really works for my Timeline 3830TG as well!
    However, when I plugged earphone, the internal speaker keep working.
    I expect when I plug earphone, the speaker should be stopped.
    Do you know how to solve this problem?

      This freezes my system on installation. I can’t even change to another tty to login and kill it. Had to to a hard shutdown :(.

      Sometimes I hate Linux. Its OK on desktops, but the laptop vendors just don’t provide enough compatible drivers to use Linux in a productive environment.

    Didn’t work for me. Got :

    /usr/bin/python: /usr/bin/python : fichier binaire impossible à lancer

    It’s in french. Mean “binary file impossible to execute”

    Any idea ? I’m a newbie :)


    You can look for this post here and hope it will be help full for you….cheers

    This fix did not work for me. Disabling EAPD (it was activated in the beginning) did nothing.

    Hi everyone, on an acer 4830tg timelinex I tried the soution proposed in the beginning:
    wget -O
    sudo python

    and then selected “enable” in node 0x1b and selected NO when it asks to reverse.

    It worked for a while but after every update I had to do it again (and then worked until the next update).
    My problem is that after my last update today this solution doesn’t work anymore… Any idea????
