The Zbook 15 G3 is currently running:
- kernel: 4.13.0-38-generic
- NVidia: 384.111-0ubuntu0.17.10.1
lspci | grep -i nvi 01:00.0 VGA compatible controller: NVIDIA Corporation GM107GLM [Quadro M1000M] (rev a2) 01:00.1 Audio device: NVIDIA Corporation Device 0fbc (rev a1)
I can't get any output at all through the analog ports. I know audio does work because I get audio through a Plantranics headset with a USB dongle but the internal speakers and the headset port on the side are completely silent.
This post seemed to be closest to my issue, and it changed the behavior somewhat as I now see the NVidia hda device:
I added this to
### Load analog device 4/19 #https://wiki.archlinux.org/index.php/PulseAudio/Examples#Simultaneous_HDMI_and_analog_output load-module module-alsa-sink device=hdmi:0 load-module module-combine-sink sink_name=combined set-default-sink combined
The only thing this changed is that in pavucontrol I can now see the NVidia HDA device but not on the 'Configuration' tab.
aplay -l shows the same output even after that is done and a reboot:
**** List of PLAYBACK Hardware Devices **** card 0: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: NVidia [HDA NVidia], device 7: HDMI 1 [HDMI 1] Subdevices: 1/1 Subdevice #0: subdevice #0

Syslog shows this repeating, so something isn't right:
Apr 19 10:17:19 rbeldin-HP-ZBook-15-G3 pulseaudio: [pulseaudio] sink-input.c: Failed to create sink input: sink is suspended.
Oddly, if I bring up pavucontrol I can see the output levels moving even as there is no sound. Under configuration the only device that shows up is the "Digital Stereo HDMI (Unplugged)" which is correct because I don't have an external monitor connected right now.
From the BIOS level, the only things I had to do was change the video to discrete graphics and turn off secure boot for NVidia. It is my recollection that this briefly worked with the inbox nv driver, but I am not too sure about that.
Not sure how to proceed at this point or what data to collect. Any ideas would be helpful. I have full alsa-info but it is lengthy but would be willing to share if that would be of interest.
