Ubuntu is notorious for its audio problems. Both Desktop PCs as well as laptops mostly fail to recognize the audio device. This post is specifically meant for solving the audio problem in Ubuntu in Sony Vaio laptops.
Reason for failed Audio
Ubuntu 10.04 is loaded with the old version of ALSA (Advanced Linux Sound Architecture) , which fails to play most of the audio devices. To solve this problem simply upgrade to the latest version of ALSA and reboot.
How to Upgrade ALSA Driver
One of the blogger has given a detailed instruction on how to upgrade the ALSA driver. I strongly recommend you to follow the instructions (http://monespaceperso.org/blog-en/2010/05/02/upgrade-alsa-1-0-23-on-ubuntu-lucid-lynx-10-04/). Once you follow the instructions in the link above do the following steps.
- Add this code into the repository ppa:ubuntu-audio-dev/ppa
- Update the repository
- Then in the terminal enter the following code sudo apt-get install linux-alsa-driver-modules-2.6.32-22-generic
- (In the above code, change the version accordingly)
- In the terminal enter sudo apt-get install linux-backports-alsa-2.6.32-22-generic
- Reboot the machine
- By default the volumes will be low, so open any sound mixer and increase the volume ( You can use alsaconf , pulse audio or the inbuilt audio configure window)
Loading
Linux looks good and works good too but these small problems always seems to rise up
The package you want to install is linux-backports-modules-alsa-lucid-generic (not ‘lucid’ instead of the the kernel version). Otherwise you will have to manually update the backports package whenever a new kernel package is released (which is pretty often these days).
People,
I used to have the same problem with the audio and I could fix it.
Details:
Laptop model: Sony VAIO VPCEE43EL (but it should work with all the VAIO series).
Ubuntu version: Ubuntu 10.10 & Ubuntu 11.04 (I tried with both).
How to fix it:
(1) Go to the speaker icon and select Sound Preferences.
(2) Make sure there’s no program using the sound under Application tab.
(3) Go to Hardware Tab and select Analog Stereo Output from the drop dawn list.
(4) Go to Output Tab and under Connector select Analog Speakers.
(5) Now, go to Hardware Tap again and select Test Speakers. It should work.
Extra recommendations:
(A) Probably it’s going to be a good idea to restart the computer.
(B) I recommend to test sound with headphones to make sure that we’re not talking about a different problem.
Good luck!
