Bug Description
=== SRU Justification ===
[Impact]
Some Nvidia graphics card has audio function in addition to video
function. When the video function is not bound to any driver, the audio
function can't be runtime suspended, hence preventing the power
resources from being turned off.
[Fix]
Allow Nvidia audio function to be runtime suspended.
[Test]
The user reported the fix works.
[Regression Potential]
Low. It only allows the audio function of discrete Nvidia GPU to be
runtime suspended. Regular audio or audio function with a discrete GPU
already bound to a driver are unaffected.
=== Original Bug Report ===
After updating to 5.0.0-25-generic kernel, battery life is considerably less and power consumption is about 10 watts more idle, using integrated graphics. This is a hybrid GPU laptop Intel HD 630/GP107M, and a possible cause is not powering off the dedicated GPU completely while using the integrated.
