I'm gonna try to explain, after your email, I think it will be a good idea to add some explanation in the chapter. The output from dmesg: pcm0: <Realtek ALC892 Analog> at nid 23 and 26 on hdaa0 pcm1: <Realtek ALC892 Right Analog Headphones> at nid 22 on hdaa0 The lines in /boot/device.hints: hint.hdac.0.cad0.nid22.config="as=1 seq=15 device=Headphones" hint.hdac.0.cad0.nid26.config="as=2 seq=0 device=speakers" nid22 makes reference to "at nid 22" as makes reference to the association number, more info [1] seq makes reference to the sequence number, more info [1] > What is "esound"? We haven't mentioned it and it doesn't seem to be in ports. This one [2], maybe we need to remove the reference in the chapter, too [1] https://man.freebsd.org/cgi/man.cgi?query=snd_hda&sektion=4&manpath=freebsd-release-ports [2] https://www.freshports.org/audio/esound
