Hello,

I re-installed a newly arrived Tensorbook with a dual-boot Windows/Ubuntu 18.04.2 LTS  
Everything works find but the audio on Ubuntu.

I only installed lambda-stack-cuda, everything else is base Ubuntu.

lspci -nnk | grep -A2 Audio gives

00:1f.3 Audio device [0403]: Intel Corporation Cannon Lake PCH cAVS [8086:a348] (rev 10)  
Subsystem: CLEVO/KAPOK Computer Device [1558:96e1]  
Kernel driver in use: snd\_hda\_intel

01:00.1 Audio device [0403]: NVIDIA Corporation Device [10de:10f9] (rev a1)  
Subsystem: CLEVO/KAPOK Computer Device [1558:95e1]  
Kernel driver in use: snd\_hda\_intel

I have been looking for a while now but cannot figure out why there is no audio.

Thanks a lot for your help.
