[alsa-devel] [PATCH v2] ALSA: x86: Select CONFIG_HDMI_LPE_AUDIO as default

[Ian W MORRISON]

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
