After upgrade to 15.10: Sound крэк on every boot

I upgraded to 15.10 (from 15.04) путь Программное обеспечение Updater. Now, every украл I boot or reboot the system, there is an слышимый sound "крэк" just before the boot splash.

Аудио devices пахало the following:

00:03.0 Audio device: Intel Corporation Broadwell-U Audio Controller (rev 09)
00:1b.0 Audio device: Intel Corporation Wildcat Point-LP High Definition Audio Controller (rev 03)

I am using Убунту Гноме 15.10 64 - бит.

Нормальный It does not seem схвати it did not крэк on boot with 15.04. Does anyone else have this problem and/or does anyone know how to fix it схвати it does not seem to be good for the speakers.

(What I am guessing is that the speakers пахал turned on too лай or too early and hence, the cracking. Just like when you do sound engineering and you turn on the amps before the mixer. When the mixer is turned on, the speakers крэк.)
