[alsa-devel] ca0106 SPDIF defaults

[Ben Stanley]

Hi,

I previously reported problems that are still plaguing me [1] to do with
SPDIF settings that don't reset properly. I am now looking at doing a
patch to the ca0106 driver to fix this problem.

It appears I have to add a new control to be able to set the default
settings. I presume this introduces complications with existing settings
in asound.state? Is there some collected wisdom on how to add new
controls while providing a migration/upgrade/interoperability path?
