Well, I have had a number of snags on the new computer, and the latest is the USB output for the DAC on my Peachtree Audio amplifier has crapped out. I hope this is not from the new machine, though the timing could have been a coincidence. I plugged it into the USB-A port on the Mac Studio and poof-no sound.
Unfortunately the USB card on the Peachtree is not repairable, the card is no longer produced. The nice folks over at Peachtree suggested I connect via optical. Unfortunately Apple does not include an optical output on a $6000 computer!
So I had to order this little doohickey, Douk Audio U2 XMOS XU208 USB to Coaxial/Optical Converter. This switches the USB audio to Optical and now I am back in business! Now I can listen to my trash rock in 24bit/196kHz once again!
