[alsa-devel] [PATCH 2/3] ASoC: rt1308: add silence detection and manual PDB control

[shumingf at realtek.com]

From: Shuming Fan <shumingf at realtek.com>

We enable the silence detection function in initial settings.
PDB control changes to manual mode, hence the driver could
fully control the AMP output on/off.
