Public bug reported:
I have an Intel audio on my HP laptop.
When playing any sound (e.g. warning sounds from command line, etc.) the output
I hear is a loud crack in speakers and than the sound. The speakers do the
crack sound even when the headphones are connected, just the sound is played
back in the headphones only.
It seems like something with power saving - windows is performing simmiliar
behaviour. But I still have an installation of Intrepid and there is no such
thing - the playback is smooth, no cracking, nothing. The cracking sound does
not appear when playing two sounds with minimal time difference (e.g. 10
seconds), but with bigger difference (e.g. a minute), the cracking is back.
Also, now I noticed, that before the playback the mute icon (the diode on the
laptop body, not the indicator in main panel of Ubuntu) shines for a short
time, than turns off again. Maybe that's the reason of the cracking sound, but
as I said, such behaviour did not exists in Intrepid.
