I have a question regarding the sample rate converters in the ADAU144X family.
If I connect a digital source during the DSP is running ("hot docking") I have severe pop noise on the outputs.
Even if I only press the "Pause" button on my digital source (in this case a CD-Player) I reckognize a rather silent click or pop noise.
These problems are almost gone, when I bypass the SRC by using the "SPDIF input" module instead of the "ASRC input" module (in this case the source of course needs to have the same sample rate as the DSP sample rate).
Is there any chance to make use of the "SPDIF input lock bit" (addr 57545) for solving my problems?
Any recommendations are welcome!
