Sound Device • Re: [Solved] No USB Sound 2.1 kit

I followed these instructions to geta USB audio adapter working so I could use headphones on my Thinkpad T480s laptop. As a novice, I wasn't sure where this was supposed to be pasted:

Loading the driver:
CODE: SELECT ALL

kldload snd_driver

I guessed it was part of what was to be added here:

sudo nano /boot/loader.conf

and that turned out to be correct.

Also, I think this may have a typo?

# /etc/devd/usb_hp.conf
attach 100 {
device-name "pcm?";
action "sysctl hw.snd.default_unit=?";
};

detach 100 {
device-name "pcm?";
action "sysctl hw.snd.default_unit=0";
};

Should that last line "sysctl hw.snd.default_unit=0" be "sysctl hw.snd.default_unit=?" with a question mark instead of a zero? My USB audio adapter is pcm3, so I changed all the question marks to 3's, and I used "sysctl hw.snd.default_unit=3" and that seems to have worked.
