[alsa-devel] Smart5.1 switch and 6 audio jacks motherboard

[Raymond Yau]

Refer to commit 1564b2878f5cf160f60af99d4dbca1dd7809ee8a

ALSA: HDA VIA: Add smart5.1 function.

Smart 5.1 is for 3-jacks model, to reuse input pins as outputs.
While off, they act as "line out" / "line in" / "mic in".
While on, they acts as "line out" / "back left/right" / "center/lfe".

There are several bug report related to Smart 5.1 switch and motherboard
with 6 audio jacks at rear panel

Should the driver deactivate or remove "Smart 5.1" switch for the
motherboard which does not need reuse input pins as outputs (e.g.
motherboard with 5 or 6 audio jacks at rear panel) ?
