[SRU] [B/D/E] [PATCH 0/1] Fix XPS 13 headphone noise

Kai-Heng Feng
BugLink: https://bugs.launchpad.net/bugs/1654448

[Impact]
XPS 13 9350/9360 has unbearlbe headphone noise after recent kernel
updates.

[Fix]
Lock Headphone Mic Boost level to 1 as an workaround to solve the issue.

[Test]
Plug a headphone to audio jack, the noise is really bad.
After applying the patch the noise is gone.

[Regression Potenial]
Low. This change only targets to 2 systems, so it has limited impact.

[PATCH 1/1] ALSA: hda/realtek: Reduce the Headphone static noise on XPS 9350/9360

Kai-Heng Feng
BugLink: https://bugs.launchpad.net/bugs/1654448

Headphone on XPS 9350/9360 produces a background white noise. The The
noise level somehow correlates with "Headphone Mic Boost", when it sets
to 1 the noise disappears. However, doing this has a side effect, which
also decreases the overall headphone volume so I didn't send the patch
upstream.

The noise was bearable back then, but after commit 717f43d81afc ("ALSA:
hda/realtek - Update headset mode for ALC256") the noise exacerbates to
a point it starts hurting ears.

So let's use the workaround to set "Headphone Mic Boost" to 1 and lock
it so it's not touchable by userspace.

For Bionic this was already picked up via stable and is pending release in this
cycle. For Disco it was already picked up and is queued to be included in the
upcoming cycle. So far it is not yet in Eoan (but might be in one of the yet
unapplied stables).
