Hmm…so that doesn’t actually exist as you suggest.
I’d found another thread that suggested it should be in /etc but that also does not exist.
For the record, this is a Pi 4 B, no hats; just trying to leverage the onboard USB output to an SMSL DAC, which it sees…
pi@PlexampLounge:/etc $ lsusb

The alsa.conf file does exist in /usr/share/alsa but beyond that…
For the record, aplay -l also gives the same output as the ALSA output in my OP.
In this thread, it seems to work…so clearly something is different here but there’s no reference to this anywhere that I can see. I’m a little confused as to what’s missing here given the assumption that the original install steps were accurate and the corresponding packages have everything required.
