Hi Will, All,
Just pushed new commit 131ace1.
Don't panic about 8 removed files. If you will ever need them, you can
checkout any previous commit and they will appear again.
Here is a step-by-step explanation of new changes:
I removed 8 files: AlsaJackClient.cpp/h, JackClient.cpp/h,
JackAlsaClient.cpp/h, AlsaJackClient.cpp/h.
Now all combo driver functionality is handled by one class: MusicClient.
Interface became more universal. How it works:
Here is the function newMusicClient in MusicClient class. Before my
changes this function created default audio/midi driver pair and if this
had no success, yoshimi simply failed to start.
Now the behavior is different.
There are 3 drivers for audio: jack_audio, alsa_audio, null_audio
and 3 drivers for midi: jack_midi, alsa_midi, null_midi.
When creating new music client, default driver pair is tested first. If
it fails, then new algorithm tries to open combos in following order:
jack_audio/jack_midi (if is was not the first)
jack_audio/alsa_midi
alsa_audio/alsa_midi
jack_audio/no_midi
alsa_audio/no_midi
no_audio/no_midi
Now yoshimi will never fail it's startup because of new driver
'no_audio' which is a simple thread, that calls masterAudio at constant
intervals emulating virtual audio device.
Now, if default audio/midi pair fails, no questions are asked and
fallback pairs are probed automatically. Don't know if there is a
probability that user will tap 'No' to question about switching to
alternate pair.
