Use dedicated messages for flow control instead of abusing clock tick messages and enable flow control for MIDI. Since this requires protocol version bump, both sndiod and libsndio must be kept up to date to work together.

Implement a new authentication method allowing aucat and midicat to work over TCP, for instance, to expose the sound card of one machine with other machines of the network. The first client generates a 128-bit random number (aka the session cookie), saves it in $HOME/.aucat_cookie and sends it to the server. Successive clients load the cookie from $HOME/.aucat_cookie and send it to the server but the server accepts only clients whose cookie matches the session cookie. When all clients are gone, the session is over, and another cookie could start a new session, and so on. TCP is enabled on the server with the new -L option, and on the client side hostnames are specified with a new optional component in the device name. hints from damien, dlg and deraadt, tweaks from jmc

Don't send the initial position as a clock tick with a negative delta. Add a new ``initial position'' message which is simpler. No bahaviour change, except effects of the protocol version crank.

Allow the audio device to be opened only while it's actually used. This is necessary for uaudio devices, for instance to start aucat before the device is plugged. Or to unplug a device whithout having to restart aucat when another device is plugged. This is controlled with the new -a option. Allow multiple audio devices to be used concurently, i.e. multiple ``-f devname'' options to be used; -f options must follow per-device options, which is what we do for other options.

aucat (server):
- make the ``-m mode'' option per subdevice, allowing
subdevices to be play-only or rec-only even if the
server is full-duplex
- add ``monitoring'' mode (with ``-m mon''). This is a
record-only stream from which played streams can be
recorded (kind of ``record what you hear'').
- allow MIDI devices to be subscribed to the controlling
MIDI port of the server, ie what midicat does (with -f
option), but using the -q option.
- add flow control to the protocol, and serialize clock
ticks (sio_onmove() calls) and data chunks. This should
fix certain full-duplex programs, broken with ``magic''
block/buffer size combinations.
- enable 3 block latency which is the minimum theoretical.
Make -z and -b options correspond to device parameters.
- make sio_getcap(3) the same for aucat and sun backends,
ie return whatever is supported (``everything'' in the
aucat case, since everything is actulally supported).
aucat (player):
- enable ``-m mode'' option to select between monitoring
and recording when ``-o file'' is used.
- plug MIDI code to non-server codepath. The MIDI control
device is specified with the ``-q device'' option, as in
server mode.
- impliment lseek()'ing within files (controlled
through MIDI). Necessary to use aucat with a MIDI
sequencer.
midicat (thrubox):
- rename ``-f'' flag to ``-q'', so it has the
same name as in aucat (-f is still working)

don't mess with audio internals from within the midi bits. Instead use a call-back interface. This allows easily sending volume changes feedback to audio applications.

make aucat(1) expose a MIDI device to control server behaviour in realtime. For now only the playback volume of individual streams can be changed/monitored. To each stream is assigned a MIDI channel; the volume is changed/monitored using the standard controller number 7.

Currently midi capable programs can control midi hardware, but cannot cooperate with other programs. The aim of this change is to allow any program to send midi data to other programs as they were midi hardware. For instance, this change should solve the longstanding problem of using a midi sequencer with software synthesizers. More precisely: - new midicat(1) utility (actually hardlink to aucat(1)). it creates software midi thru boxes, allowing programs to send midi messages to other programs as they were midi(4) hardware. - new midi api in libsndio (see mio_open(3)), to access midi(4) devices and midicat(1) sockets in a uniform way. - new device naming scheme <service>:<unit>[.<option>], common to audio and midi. - new sndio(7) manual describing concepts and naming The current audio device naming still works, but people having scripts or configuration files containing device names could read the sndio(7) man page and slowly start updating device names. discussed with jakemsr@ and deraadt@, help form jmc@

Make clients inherit the volume parameter when the -v option is used in server mode. It gives the maximum volume a client may have. This wastes dynamic range, but allows volume to stay constant when other clients connect or disconnect.

add minimal server capability to aucat(1). When started in server mode, it listens on an unix socket and mixes/demultiplexes any number of full-duplex streams, doing necessary format conversions and resampling on the fly. programs can use the new libsa(3) library to play and record audio. The library provides a very simple API to connect to the audio server; if aucat(1) isn't running, it uses the audio(4) driver transparently instead.
