I have a question regarding the on-disk format. Let's say that we have
an alsa card that has options hardware_volume_enabled and ignore_dB.
hardware_volume_enabled is a core option, i.e. not specific to alsa,
and ignore_dB is specific to alsa. The current proposal would probably
be to write the options on disk as follows:
core.port.<card_name>.port.<port_name>.hardware_volume_enabled = true
alsa.port.<card_name>.port.<port_name>.ignore_dB = true
What do you think of the following alternative format?
hardware_volume_enabled = true
ignore_dB = true
I would prefer this approach, because it seems cleaner to me, and it's
more consistent with how the existing alsa mixer configuration looks

I plan to jump in...
