* Add version number to aucat protocol. It's not used yet,ratchov2009-10-171-1/+2
| | | | | | | but later, it will permit aucat to reject connections from clients statically linked to a unsupported version of libsndio. idea from kittenis, otto and sthen
* when setting parameters of sun devices, check that selected encodingratchov2009-10-101-4/+23
| | | | is actually linear
* at initialization of sun devices, use sio_setpar(3) instead ofratchov2009-10-101-11/+10
| | | | | AUDIO_SETINFO() to set the initial parameters, since AUDIO_SETINFO() can fail.
* since AUDIO_INITINFO() may set parameters to whatever is supportedratchov2009-10-101-24/+59
| | | | | | | | by the device, we may end up with different recording and playback parameters, which will break almost all full duplex apps on such devices. For instance, this should fix full-duplex apps not working on devices that can record at any sample rate but can play at 48kHz only.
* don't consider calling sio_close() without calling sio_stop() firstratchov2009-08-282-6/+4
| | | | | as a programming error. At any stage the program should be alble to cleanly free resources and close the device.
* when using aucat backend, wait for the server to drop the connectionratchov2009-08-281-2/+7

* add a new AMSG_BYE, sent by the client to requst the server toratchov2009-08-282-2/+12

| | | | | | 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, butratchov2009-07-2511-37/+963
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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@
