* fix: stop the DirectAudio output while the sink is suspended
* fix: verify every session thread before reporting suspension
* fix: freeze PRoot first and stop each guest thread on suspend

- Pace the session at the rate the panel actually runs. When the system
keeps a lower rate than the mode DroidDeck asked for (a vendor game
assistant holding 120 Hz while 185 Hz was requested), gamescope,
Xwayland and the compositor's presentation feedback were told 185 Hz,
and Steam's interface drew every 10.8 ms out of step with the panel.
- Build the DirectAudio PulseAudio sink from source (LGPL-2.1-or-later,
The412Banner/directaudio v1.1.0) with its max request kept to its ring
target. Advertising 100 ms made PulseAudio grow every client's buffer
to about 112 ms, so Steam's interface sounds played that late.
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creating a missing prefix first (proton run wineboot) were tried on the device and withdrawn: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.
