Add events when PCM availability changes
Add PCM availability application framework events to be notified
when ALSA PCM availability changes.
Use subscribe verb and json
'{ "event" : "pcm", "name" : "hw:3,2,1", "stream" : 0 }'
to subscribe to playback PCM 'hw:3,2,1' availability events.
Use subscribe verb and json
'{ "event" : "pcm", "name" : "hw:1,2,3", "stream" : 1 }''
to subscribe to capture PCM 'hw:1,2,3' availability events.
from removed card events.
To handle PCM events, inode notification (using inotify) is used
on '/dev/snd/pcm*' file (e.g. '/dev/snd/pcmC0D0p')
to monitor PCM availability.
