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 run.py http://www.alsa-project.org/hda-analyzer.py
sudo python run.py
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 click “Node[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.
