The upstream kernel builds for distributions such as Ubuntu which now includes binary packages for v4.11 mainline kernel release candidates are promoted as a way of testing upstream kernels to to confirm that upstream has fixed a specific issue (see https://wiki.ubuntu.com/ Kernel/MainlineBuilds).
Unfortunately the long awaited patch for providing HDMI audio support for Bay Trail and Cherry Trail devices does not include this support through
a
module built by default.
Through including by default of the two associated CONFIG settings
(SND_X86
and HDMI_LPE_AUDIO), upstream kernel builds would automatically provide
the
much desired HDMI audio support by default.
This patch uses a Kconfig 'default' statement to include the driver as default.
Changes in version 2: CONFIG_SND_X86 now a bool and changed default m to default y

It's distributor's job to choose the right config here.
Actually this goes back to one of my earlier points: A distributor doesn't
have to set 'HDMI' as HDMI audio is automatically provided. This is just an extension because by setting 'HDMI_LPE_AUDIO' the missing audio support for BYT and CHT SoCs is then provided. Therefore, in this albeit unusual instance, I reason is it appropriate to set HDMI_LPE_AUDIO so that audio is automatically provided regardless of distribution. If a distributor didn't want to allow audio for BYT and CHT SoC based devices running their distro then they could always remove it from their distro specific config.
