Audio on Linux: The End of a Golden Age?
summary
Claims that the consumer Linux audio “golden age” is ending because hardware is shifting back toward DSPs and richer codecs; historical fixes include ALSA ASoC (merged 2006) for reusable components and fine-grained power control and PulseAudio which unified competing sound servers and largely made desktop audio “just work.” Measured evidence: ~14,700 audio commits in the last five years, ~500 to ALSA core, ~2,100 to HDA, ~600 to USB, and embedded/ASoC accounts for roughly two thirds of activity. Proposed fixes: topology and a use case manager for per-device profiles, but topology’s tight coupling to ASoC complicates long‑term redesign.
