# Tensorbook - Ubuntu 18 No sound

## post by god_kane on Mar 7, 2019

Hello,

I re-installed a newly arrived Tensorbook with a dual-boot Windows/Ubuntu 18.04.2 LTS

Everything works fine but the audio on Ubuntu.

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

```bash
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.

Try `sudo ubuntu-drivers autoinstall`

Yes I tried that but it just said there is nothing to install.

Hello God Kane,

```bash
echo "options snd_hda_intel probe_mask=1" | sudo tee /etc/modprobe.d/tensorbook.conf
sudo update-initramfs -u -k all
```

Then reboot.

Awesome. Just tried and it works.

I actually tried that module probe_mask option before but not on its own.

Maybe it did not work anyway with the kernel version that was there when I received the machine?

Anyway my kernel is “5.0.0-31-generic #33~18.04.1-Ubuntu” and now I got sound on the built-in speakers.

Thanks!
