n of a program subscribing to a port, and a client
subscribing itself to a port, and a third client subscribing to two ports.
What do these mean? And why are SUBS permission bits needed in some cases
but not others? In short, what IS "subscription"?

My first try was to leave snd as a built-in module, and pass the slo
e the names the same as in /proc/asound/modules?
The subsidiary ones are, but snd isn't. Can this parameter be supplied on
the kernel command line as snd.slots=...? Or would it be better to
recompile the kernel with snd as a module? If so, what's the CONFIG_
symbol?

parameter as an option to the individual drivers, but the hifiberry
doesn't understand it.
Did something change in 2.1.2? Or am I doing something wrong? Is "snd" no
longer the name of the top level ALSA sound module? I don't see it listed
in lsmod.

Check out the vibrant tec

as "Interface", and an E-Mu device called "XMidiX1". It would be really
nice to have some geographic way to refer to them, based on the USB port
they're plugged into. But I guess that's something I should ask about on
the systemd list.

Or barring that, what else can I do so that my app can use fixed names for

those are really

So how does one programmatically find the range of a control? I'd prefer to
have plain linear voltage control, but I'll take anything I can get as long
as I know what the shape of the curve is.

For the API, the dB values are
(integer_value_returned_from_the_API_call / 100) in order to avoid
floating point.
Does this help?
Yes. I'll have to copy amixer from my Ubuntu system to see this, because my
embedded system only has alsamixer.
