So we've had mention 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?

so tried adding the
index 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.
x27;m asking because my sound output isn't
working, even though those parameters seem reasonable and it's not
complaining.

? Alternatively, would the extra overhead of reducing the
period size to 64 (96KHz stereo 32-bit LE on a Raspberry Pi 3) be
significant?

consistent name with each USB port, even if it doesn't gracefully handle
cases like external hubs.

Check out th
nverter whose name comes up
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 lis
umbers?
Or barring that, what else can I do so that my app can use fixed names for
referring to both?

Check out the vibrant tech co
driver, built into alsalib, or
arbitrary? How about "IEC958 Playback Switch"? What about "index 16"? Is
the "access" item alsalib's way of telling me that this is a read/write
variable, which it knows from the driver, or is it somebody's way of
telling alsal
f or legacy mode, both of which behave the same.
There is nothing specifically about the digital output.
Is there something in Alsa I'm supposed to do to enable this output? And
if it's not enabled, why can I successfully open it and write to it?

d a dbmax of 0. (I assume those are really
millibels.)
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.

Precog is a next-generation analytics platform capable of advanced
analytics on semi-structured data. The platfor
han that. In
fact, given the wretched state of ALSA documentation, I hope I never have to
know another thing about ALSA, once I've found the answer to this one last
question.
Thanks in advance.
