Bug Description
Hi!
I have Ubuntu 14.04 LTS with kernel 3.19.0-25 installed in a HP Probook 430 G3. When I finished the installation, the sound doesn't works.
I followed the Andy C instructions and it works. I didn't use the alsa_setup.sh script.
-I only put this lines in /etc/modprobe.
options snd-hda-intel single_cmd=1
options snd-hda-intel probe_mask=1
options snd-hda-intel model=basic
But when I reboot the laptop (not halt or poweroff), before Ubuntu boots, a very strong noise appears. At every reboot this noise appears.
-I corrected this problem, I just put the next line in /etc/modprobe.
options snd-hda-intel power_save=0
Now, I've updated the kernel to 3.19.0-47 and the strong noise appears again.
I've tried to solve adding another option to the file:
options snd-hda-intel power_save_
But doesn't works....
I've read the kernel documentation pages about ALSA but I haven't find the solution

Has someone got an idea to resolve this issue?
Thanks to all!

Hi!
I think I've resolved it.
I entered into BIOS setup and I enabled an option called "Intel Smart Sound"
I'm testing it, if the problem don't appear again, I will consider it resolved!
Tanks to all!
