AlsaInLumSpec
Please check the status of this specification in Launchpad before editing it. If it is Approved, contact the Assignee or another knowledgeable person before making changes.
Launchpad Entry: kernel-alsa-in-lum
Packages affected: linux-ubuntu-modules, linux-source
Summary
Alsa is a fast moving tree, especially in areas such as HDA sound. Stock kernel sound drivers are rarely (if ever) up-to-date enough to handle latest hardware.
Moving alsa drivers to lum, and syncing with upstream more regularly, will help alleviate this problem.
Release Note
More up-to-date sound drivers.
Rationale
After every release, we are constantly trying to keep up with latest HDA sound driver to work with newer laptops and desktops. These updates are generally driven by vendor obligations. Some of these updates require changes to the core sound driver, and thus become very tedious.
Use Cases
Assumptions
Design
You can have subsections that better describe specific parts of the issue.
Implementation
This section should describe a plan of action (the "how") to implement the changes discussed. Could include subsections like:
UI Changes
Should cover changes required to the UI, or specific UI that is required to implement this
Code Changes
Code changes should include an overview of what needs to change, and in some cases even the specific details.
Migration
Include:
- data migration, if any
- redirects from old URLs to new ones, if any
- how users will be pointed to the new way of doing things, if necessary.
Test/Demo Plan
It's important that we are able to test new features, and demonstrate them to users. Use this section to describe a short plan that anybody can follow that demonstrates the feature is working. This can then be used during CD testing, and to show off after release.
This need not be added or completed until the specification is nearing beta.
Outstanding Issues
This should highlight any issues that should be addressed in further specifications, and not problems with the specification itself; since any specification with problems cannot be approved.
BoF agenda and discussion
Looks like we'll just follow alsa in our kernel tree, using alsa's ksync script to update our sources based on upstream alsa point releases.
After release, we can use linux-backports-modules to update specific drivers (usually snd-hda-intel).
