Linux Compatible Audio Interfaces

This is a list of USB, FireWire, and PCIE audio interfaces that I have tested for Linux compatibility. Some work, some kinda work, and some technically function if you squint a little.

Additionally, I have measured the round-trip latency for those interested in monitoring post-effects audio in real-time.

ROUND-TRIP LATENCY BENCHMARKS

While many kinds of audio metrics exist, one useful and well-understood metric is round-trip latency; the time it takes for an audio signal to enter the input of a device, get processed, and exit the output.
