Research getting rid of hardcoded audio conf files

Registered by Tom Gall

It has been observed that the user space audio text configuration files should instead be read on demand from the kernel. This might be accomplish via /proc /sys and / or device trees. This blueprint represents the first steps to research the feasibility of this goal.

Meta:
Roadmap id: MMWG2012-ENABLE-DEVICE-TREE-USE-AUDIO

Headline: The MMWG has recommendations for how to get rid of the various audio configuration files instead using some identified mechanism to read the information from the kernel or has a good reason why hard coded text files are a good idea for audio config.

Output: List of hard coded config files used by sound/audio in Linux:

alsa-lib:
/usr/share/alsa/alsa.conf
/etc/asound.conf
~/.asoundrc (obsolete)

pulseaudio:
/usr/share/pulseaudio/alsa-mixer/paths/*
/usr/share/pulseaudio/alsa-mixer/profile-sets/*

(?)
