I've bought an HP ProBook 450 G3 and installed Ubuntu 15.10 on it. And there is no sound at all. I tried to google the decigion, but failed.
Please help me with my issue.
Solved! Go to Solution.

I was just able to get my 450 G3 sound working with this answer on askubuntu:
I'll also copy in the instructions in case HP removes the link:
I found the solution (!), create a new file /etc/modprobe.d/intel.conf
add the following options:
options snd-hda-intel single_cmd=1 options snd-hda-intel probe_mask=1
**NOTE: I'd make sure, if you have any data on there, that you back it up, just in case (I ran into no problems, though). I'm Linux system admin, and I still make sure I have a recent backup of any system I make system modifications on, just to be safe.

Meanwhile, there's a similar bug report and a solution for HP Probook 470 G3 at
The patch was merged in kernel 4.4.4 (works on HP Probook 430 G3 over here).
(According to ALSA-Configuration.txt, single command mode should be avoided as much as possible.)

Just upgrade kernel version to 4.4 or higher. It solved my problem on 450 G3.
