PD#SWPL-139800 Problem: SC2 far field voice need early suspend and record with dsp. Solution: When DSP waked up by VAD, then: 1. DSP notify to AOCPU (would fail by unknown cmd) and ARM during early suspend. 2. DSP notify to AOCPU (would fail by unknown cmd) and ARM (would fail by timeout) and do retry after ARM deep sleep and before AOCPU STR poweroff. 3. DSP notify to AOCPU after AOCPU STR poweroff. 4. when ffv not supported, dsp do not start vwe.
