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 starts, 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 an idea to resolve this issue?
Thanks to all!
