Bug Description
The author of this config (<email address hidden>)
suggested that we should disable this config from ubuntu artful
kernel, he said, "this is really for test environments or platforms
with a connector. I don't think it should be enabled by default
(better to fail the probe rather than get questions from users that
they have no sound)."
I also investigated this issue on my own, if our kernel is running on
a platform which has a codec and the codec is supported by the
existing driver, enabling this config will not bring side effect;
if the platform has a codec but the codec is not supported by existing
driver yet, the driver will fallback to this NOCODEC_MACH if this
config is enabled, and snd-soc-
into the kernel, then user is easily confused that the kernel driver
is loaded but I can't hear sound from the codec.
