Hi!

 

I was just able to get my 450 G3 sound working with this answer on askubuntu:

 

http://askubuntu.com/questions/700167/no-sound-on-ubuntu-15-10

 

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

reboot....

 

**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

 

https://bugzilla.kernel.org/show_bug.cgi?id=112731

 

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.

Here is the thread from Pulseaudio package: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1542846
