Note there is a comparable list on the Wiki “Multichannel Recording” page. I’ve just updated that with the information from this topic, and some information based on other reports.
Just to be clear, this topic is about Windows and possibly Linux, is that so? I thought multi-channel recording in Audacity usually worked on Mac because multi-channel hardware normally works in Core Audio without requiring ASIO (Koz suggested off-forum to me this wasn’t always so).
There’s also an overlap with Recommended Sound Devices on the Wiki but perhaps that should be confined to cases where we have a detailed report.
BTW the link in the above post to M-Audio FastTrack Ultra 8R (usb)
(https://forum.audacityteam.org/t/multitrack-recording-direct-to-audacity-or-external-device/11580/1) doesn’t seem to have anything about FastTrack Ultra.
