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.

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!
