Warning: 9038D contains a high-sensitive I/V stage that may cause audible noise when your phone uses LTE 4G 5g. Some newest hardware may have issues like stuttering with USB3(Macbook pro 2020 MS Sufrrase 2020 Lenovo Carbone 2020 Acer SF313-52-71Y7 2020). USB audio-bridge manufacturer was informed about that and we expecting the FW solution.
