[Solved!][HP ProBook 430 G3, Conexant CX20724, Speaker, Internal] Underruns, dropouts or crackling sound

[ArnauC]

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.d/alsa-base.conf
        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.d/alsa-base.conf
         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_controller=N
But doesn't works....

I've read the kernel documentation pages about ALSA but I haven't find the solution
https://www.kernel.org/doc/Documentation/sound/alsa/ALSA-Configuration.txt
https://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio.txt

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!

[ArnauC (arnauc)]

Yes, It works!.

'BIOS Setup' -> 'Advanced' and enable 'Intel Smart Sound. Save changes and Exit.

Now, when I reboot, there is no noise.

Hi!
I have the same issue and the same notebook, but Ubuntu 15.10 with Linux 4.2.0-27. Any recommendation?
Thanks!

Hi Mario,
Have you tried to enable the 'Intel Smart Sound' in BIOS setup?
Before Ubuntu boots, press the 'Esc' key, then go to 'BIOS setup' -> 'Advanced' -> 'Built-In Options' -> ' Intel Smart Sound'.
Exit and save changes.

[Mario Posta (kimihun)]

Thank you for your reply!
Yes, I've tried, but it doesn't works. :/
Did you do anything else?

[ArnauC (arnauc)]

Hi,

I only modified the /etc/modprobe.d/alsa-base.conf file adding this lines at the end:

        options snd-hda-intel power_save=0
        options snd-hda-intel power_save_controller=N
        options snd-hda-intel model=basic
        options snd-hda-intel single_cmd=1
        options snd-hda-intel probe_mask=1

And then I changed the BIOS configuration, as I said yesterday.

This only two steps.

[Mario Posta (kimihun)]

It works, thank you so much!
