[Chris Elmes]

Package: nvidia-driver
Version: 375.82-1~deb9u1
Severity: important

Hello,

Display port audio stops working after upgrading to version: 375.82, was
working on older version: 375.66

Debian stretch 4.9.0-4-amd64 #1 SMP Debian 4.9.51-1 (2017-09-28)

Nvidia Quadro k5200

Some more information found on Nvidia Dev talk site:

https://devtalk.nvidia.com/default/topic/1019761/linux/no-sound-using-displayport-audio-with-375-82-384-59-and-384-69/

>From kernel log:

Same output:
