The Ubuntu Kernel Team produces what they call "Crack of the Day" builds of alsa-driver code. This is the latestdevelopment code that is being worked on "upstream" and has all the most recent fixes to hardware issues. We askusers having audio problems to install these builds in order to help us identify whether the issue has alreadybeen fixed or if it's also an issue upstream.
Installing
Install with Command Line
Adding the ppa
sudo add-apt-repository ppa:ubuntu-audio-dev/ppa
sudo apt-get update
Install the linux-alsa-driver-modules package
sudo apt-get install linux-alsa-driver-modules-$(uname -r)
Note: After installing the linux-alsa-driver-modules package, your system needs to be rebooted.
Install with Synaptic Package Manager
Adding the ppa
- Open up the "Synaptic Package Manager":
System -> Administration -> Synaptic Package Manager
- Bring up the "Software Sources" dialog in the "Synaptic Package Manager":
Settings -> Repositories
- Select the "Other Software" tab in the "Software Sources" dialog.
- Click the "+Add" button.
- In the "APT line: " text input box type:
- ppa:ubuntu-audio-dev/ppa
- Click the "+Add Source" button.
- Close the "Software Sources" dialog.
- You may see a dialog box pop up which warns you that your "Repositories changed". This is a good thing and you can close the dialog.
- Since we've just added a new repository we need to update that database that knows what packages are available and where from. Update the package information by:
Edit -> Reload Package Information
