0c3fd96693 Fix confusion between ALSA output and input periods count. 
This could cause the play start threshold to be larger than the play
buffer in turn causing playback to never start.

f8795c056d Replace off-topic parts of the desciption by an architecture overview 
Remove useless (re)wording of what are audio(4) and midi(4), add a
quick description of sndiod as intermediate layer. Try to focuse on
what the sndio library and sndiod do instead of how they do it. As
suggested by schwarze, use the word "device descriptor" instead of
"device name" to avoid the common confusion with the device files.

Remove information already given in same sentence;

prefix. To avoid namespace conflicts, put program controls in a
new "app" group.

The "master.level" control is renamed to "output.level" to match the
hardware name. This way snd/0 and rsnd/0 end-up with the same control
name.

285eafeec0 Add affinity between the program and its mixer control. 
Currently, if there are two instances of the same program, sndiod will
allocate one volume control to each. If both programs disconnect and
reconnect, the information of which control is assigned to which
program is lost. This makes difficult to run two instances of a player
and crossfade between each other with a MIDI controller.

To address this, the program chooses a 32-bit "id" (for now the
process pid) and sends it to the server. The server records the id in
the client's slot structure.  When the server accepts a new
connection, it uses the id to identify the slot the client used during
the previous connection; if it was not recycled yet, it's assigned to
the program.

cbdd29c403 alsa: use (blksz - round) as start threshold. 
The threshold making poll() return POLLOUT is one block (according to
alsa library sources). If a poll-based program writes blksz - 1
samples, playback never starts but poll won't return POLLOUT either.
In turn the program deadlocks. The problem could be observed in the
sio_alsa_xrun() routine.
