Steps to reproduce:
1. Play a music track or video
2. Keep playback playing until low/critical battery notification is triggered
    (low battery < 10%, critical battery <%5 & <%2)
3. Check if the playback will be paused when the low/critical battery notification appears

Actual results:
The playback (except local video) is still keep playing when the low/battery notification is triggered, just sound volume muted for a moment, then it resumes in about 3-5 seconds before notification disappears

This sounds like reasonable behavior, do you have a ux spec saying otherwise?

[Evan Wang (wsy324)]

Ok, asked around, no one can find the spec for proving these behavior is expected, so mark it as invalid for now, and our test cases have to be updated as well.

Evan, you are welcome to edit the spec to add links to individual test cases, if that helps you keep the test cases in sync with the design. <https://wiki.ubuntu.com/Sound> Every time I use the word “should” in a spec is a testable requirement.

(And the relevant part of the Power spec is here. <https://wiki.ubuntu.com/Power#Warnings> No mention of pausing music.)
