Hi team,
Our customer has the following question
The single-ended input and single-ended output are used, and the input signal is normal. Compared with the EVM board, the hardware should be no problem.
The configuration and connection are as follows. The sound has output, but the frequency does not have low frequency. Is it a configuration problem?
