ALSA Backend Changes:
- Parse aplay -L output to get real hardware descriptions
- Description from hardware: "Cambridge Audio Cambridge Audio USB Audio 2.0, USB Audio"
- No more hardcoded CARD_NAMES for specific hardware
- Still uses CPAL to verify device exists and get max sample rate
- Blacklist filtering preserved (null, lavrate, samplerate, etc.)
Frontend Changes:
- Prefer device.description (from aplay -L) when available
- Falls back to getDevicePrettyName() translation only if no description
- ALSA Direct shows: "Cambridge Audio ... USB Audio, Front output / input"
- Not: "Cambridge Audio USB Front Output" (hardcoded translation)
Removed Hardcoding:
- Removed CS201 → "Cambridge Audio USB" (was specific to user's DAC)
- Removed C20 → "Cambridge Audio"
- Generic CARD_NAMES remain (NVidia, Intel HD Audio, etc.)
This makes device names work for ANY hardware, not just known cards.
Each backend should use native tools:
- ALSA: aplay -L
- PipeWire: pw-cli/pactl (future)
- PulseAudio: pactl (future)
