OK. I have 3.101 running on the mini-PC. I verified that it is running kernel 5.10.90. Again, the Qutest shows no info on the lsusb. (I checked it by doing the lsusb with and without the Qutest connected. The missing line has no info about vendor or product.) And according to the Qutest, 3.101 does not send ASIO formatted DSD. The Qutest only sees DSD with DoP. As I said earlier, the Qutest needs ASIO formatted DSD in order to use the higher DSD rates, such as DSD512.
When I set DSD direct in volumio, the Qutest indicates high rate PCM. According to the Qutest manual, it indicates DSD when either DoP or ASIO-formatted DSD is received.
