macOS does not allow the 3.5mm output jack and internal speakers to be used at the same time. In fact, you can't even switch between them. If the 3.5mm jack detects a connection, the internal speakers will be disabled. This small USB sound card is perfect for my needs. This solves the problem caused by macOS.
