  v0.10.4: volume slider + XInput multi-DLL fallback

  LastSkywalker released this 2026-06-01 22:10:09 +03:00 | 33 commits to main since this release

  Volume control (item #2):

  internal/audio/volume_windows.go — IAudioEndpointVolume off the
  default render endpoint (IMMDevice.Activate). Exposed
  GetVolume / StepUp(n) / StepDown(n) / SetMute as App methods.
  Step-based rather than absolute-set because
  SetMasterVolumeLevelScalar takes a float in XMM1 which
  syscall.SyscallN can't target without inline assembly; the
  Step* variants take only (this, ctx*) so they work via the
  existing callVTable helper. One step ≈ 2% (driver-defined).

  Frontend VolumePicker.tsx — full-screen modal, 21-segment
  horizontal bar visualising current step/stepCount + percentage,
  hot orange on the top 4 segments as a "loud" cue. Controller:
  ←→ ±1 step, LB/RB ±5 steps, A toggles mute, ↑ unmutes (matches
  VK_VOLUME_UP), ↓ mutes, B/Esc closes.

  Wired into DevicesMenu as a 4th tile (🔊 Громкость). Grid
  re-flowed to 4 columns.

  XInput multi-DLL fallback (item #1, palliative):

  internal/controller/xinput_windows.go — probe ALL three XInput
  DLL versions on init (1_4 / 1_3 / 9_1_0) plus the
  undocumented ordinal-100 XInputGetStateEx export from 1_3 (same
  XINPUT_STATE struct, also reports the Guide button). Try them
  in order on every poll until ONE backend reports a connected
  controller; stick with that (backend, slot) pair until it
  disconnects.

  Background: Moonlight / Sunshine ViGEm virtual gamepads
  sometimes register as XInput-class but only respond to specific
  XInput DLL versions, or only to GetStateEx. Without this the
  user had to launch Steam (Steam Input woke the slot) before
  GameSaver saw the pad. We now probe all four entry points.

  This is a palliative — the proper fix is a Windows.Gaming.Input
  fallback (WinRT API, also covers DualSense and other non-Xbox
  controllers natively). Saving for v0.11.0 with its own ADR
  because WinRT plumbing from Go is a substantial chunk
  (~400 LOC) that wants its own design pass.
