Bug#979180: ALSA now working

[ael]

I now have twinkle working again with ALSA.

A quick-and-dirty patch is to change "plughw:0,0" to  "default:" in
audio_device.cpp:-

$ diff -u audio_device.cpp audio_device.cpp_original

-				dev.device = string("default:");

 				dev.name = string(card_name) + " (";
 				dev.name += snd_pcm_info_get_name(pcminfo);
 				dev.name += ")";

The previous audio device is also stored in ~/.twinkle/twinkle.sys, so
it is very likely that will need editing as well. No doubt that can
be done from the twinkle gui as well, but I have not explored that as
well.
