Hello! In carrying out the RGZ at the rate of Microprocessor-technology, it encountered the problem of sound output. The PC has a system speaker (squeaks when a hardware error) whose port is 61, and everything works there, but I was interested in the audio output process on the laptop. With this port, if you work, then the sound does not go. What is the number of the output port on the speakers in modern laptops? Thank.
