CID: 201308-14040 HP Pavilion 14

The audio mute LED does not work on this system.
But the audio mute hotkey works as expected.

This bug might be a duplicate of bug 1379166.
But the sound card is different.

Hi,
Is this bug fixed if you use a 3.16 based kernel (in trusty, just install linux-generic-lts-utopic), and if so, is this okay or is a backport to 3.13 still needed?

[Po-Hsu Lin (cypressyew)]

Hi David,

It will be great to have it backported to 3.13, by doing so we will be able to certify them with the LTS kernel.
Thanks!!

BTW, I have verified this on 201308-14040 with 3.16.0-30, it's still not working. But it works with the latest mainline kernel 3.19.0-rc7.
