The412BannerandThe412Banner da42a5d7a7 DirectAudio from its own release: driver set per Proton interface (CachyOS fix), the Steam client's own DirectAudio sink, binaries out of tree (#439) 
DirectAudio from its own release: driver set per Proton audio interface (CachyOS fix), the Steam client's own DirectAudio sink, binaries out of tree

Games
- Two driver sets ship from the pinned DirectAudio release (tools/directaudio/release.env =
  directaudio-linux-v1.1.0, sha256-checked by tools/directaudio/fetch.sh in CI and
  build_local.sh): linux-wine11 for Valve Proton 11 / Experimental / GE-Proton, and
  linux-wine11-systhread for Proton-CachyOS, whose Wine carries the system-thread mmdevapi
  interface. steam-compatibility picks by whether the Proton's own winepulse.so imports
  PsCreateSystemThread, never by the version string (both say wine-11.0; the wrong set is
  silence). No matching set: DirectAudio off, Proton's audio runs, logged.
- Proton-CachyOS's launcher pre-sets WINE_AUDIO_DRIVER=pulse,alsa and its mmdevapi reads that
  before the registry (Valve's and GE's do not read it): the wrapper exports
  WINE_AUDIO_DRIVER=directaudio,pulse as well as writing the registry. On CachyOS this also
  makes DirectAudio engage on a game's first launch.
- A wineserver from an earlier Steam verb can save its in-memory registry over the appended
  Audio value; the wrapper says so when one is live. Writing through it (wine reg add) and
  creating a missing prefix first (proton run wineboot) were tried on the device and withdrawn:
  a second Proton/Wine run inside Steam's launch sequence got launches aborted.
- Tests: both sets, no set, no prefix (34 pass).

Steam client audio
- DirectAudio = module-directaudio-native-sink, the game driver's AAudio engine inside the
  PulseAudio daemon, one step from Android (adaptive buffer, two-burst floor, primed ring with
  fades, reopen on route change, watchdog, limiter). Default. Shared output = the previous relay
  route, kept. New pref clientAudioRoute; the old boolean is not read. If the native sink cannot
  open its stream the daemon keeps running (.nofail) and ensureClientSink loads the plain AAudio
  sink instead, logged to audio.log. Audio bundle stamp bumped.

Out of tree
- app/src/main/assets/directaudio/ is generated and ignored; tools/directaudio-relay/ and the
  vendored module-directaudio-sink.c + da_relay_proto.h are gone; tools/aaudio-sink keeps only
  module-aaudio-sink (the fallback). The release carries the relay and sink field fixes by
  MaxsTechReview (#338), credited there and in its AUTHORS.

Device-proven on an AYANEO Pocket FIT: client sink 12 ms / 4 ms bursts, 0 underruns; FEZ on
cachyos-11.0-20261005-slr on DirectAudio (took pulse before); FEZ on Proton Experimental
unchanged; Curse of the Dead Gods on CachyOS from a cold prefix, DirectAudio on first launch.
