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.
