Other Parts Discussed in Thread: TAS5614LA,

Hi team,

customer face idle noise issue on TAS5548+TAS5614LA and try to implement the TAS5548 automute function, but found some issue. need clarify below question:

1. the automute threshold in 0x14 seem not related to input signal level? does it sum all input channel noise?

2. how about the unmute delay from the automute when large signal input, customer found it unmute very slow  then some music data have been muted. 

Thanks.

Anderson
