[Canary 6427] Revert "Audio: Always choose hardware layout as output layout"

This reverts commit 620f17d013321ee9576546bab37f178f299b4821.

Reason for revert: cause https://issues.chromium.org/issues/335325895

Original change's description:
> Audio: Always choose hardware layout as output layout
>
> When we playback a 4.0 channel layout audio, and when we have
> a 5.1 channel layout Audio MIDI setup, their should be an upmix:
>
> L -> L,
> R -> R,
> C -> C,
> BC -> upmix to SL and SR
>
> In this case, we expect the output channel layout always be 5.1,
> but the previously logic limited us to use 4.0 layout, which
> causes the silent back center channel.
>
> To fix the bug, we should always use hardware layout as output
> layout no matter what.
