Public bug reported:
I was playing some audio files, the following message appears,
ALSA lib pcm.c:8424:(snd_pcm_recover) underrun occurred
And the WIFI is disconnected.
I have experienced problems,
(1)The gnome-sound-recorder sometime works sometime doesn't.
(2) Click the LibreOffice Calc, after the empty worksheet loads, when i try to
open another document by using "File->Open" on the menu, the application is not
responding at all and I have to force it quit
