I've been building a native USB Audio Class driver for AmigaOS 4 from scratch. It now supports stereo playback, 7.1 multichannel surround, recording with input switching, multi-device detection, and user-configurable device names. It's in beta

What works:

- Stereo and 7.1 multichannel playback
- Recording with Microphone, Line In, and SPDIF input switching
- Hardware volume control and input gain
- Multiple USB audio device detection and selection
- Glitch-free playback with triple-buffered isochronous transfers
- Clean start/stop without crashes
- Custom device names via prefs file
- Amiga Installer package for easy deployment

What to be aware of (beta caveats):

- Only USB Audio Class 1.0 devices are supported (covers most USB sound cards)
- Only 16-bit PCM format is currently handled
- The device must be connected before AHI initializes the driver
- Hot-plug/unplug while audio is playing will cause issues
- Not all USB audio devices have been tested — your mileage may vary
- Recording quality and input switching behavior depends on the specific USB chipsetIf you encounter problems, please capture the full serial debug log (all lines starting with [USBAudio]) and report the issue along with your device's VID:PID.

I know who should be next president ! Thumbs up ! What else except C-Media CM106 (0D8C:0102) 7.1 USB may be worth of testing ? (something up2date which can be find in shops, etc)
