alsa-project/alsa-ucm-conf pull request #737 was opened from huddx01:

Adds UCM profiles for RME Fireface 802 and UFX III devices and fixes a pre-existing bug in the existing UCX/UCX-II profiles.

New devices:
- Fireface 802 CC mode (0424:3fdd, 22ch) - tested on Debian Trixie
- Fireface 802 USB/driver mode (2a39:3fcd, 30ch) - tested, but my driver/module not yet stable enough for upstream submission
- Fireface UFX III CC mode (2a39:3fde, 94ch) - tested on Debian Trixie

Additional Bug fixes - I noticed while looking at the RME dir:
- Fireface-UCX-HiFi.conf: 9 occurrences of PlackbackPriority -> PlaybackPriority
- Fireface-UCX-II-HiFi.conf: 10 occurrences of PlackbackPriority -> PlaybackPriority,
  typo "AES3 XLR Ouptut" -> "AES3 XLR Output" (transposed letters)

Channel layout sources:
- CC mode channel count verified via /proc/asound/card*/stream0
- USB mode channel layout derived from Wireshark USB captures, see:
