Resolve through EasyEffects to its configured output device

[tzssangglass]

Problem

With Easy Effects as the default output ("Process all outputs"), the volume keys, the OSD, and the audio panel slider adjust the virtual easyeffects_sink instead of the physical sink:

• Loudness doesn't change. With a dynamics plugin in the chain (e.g. autogain), the input-level change is normalized away -- the OSD moves while the speakers stay exactly as loud.

Root cause

omarchy-audio-output-sink resolves a DSP sink's physical output by scanning pactl list sink-inputs for the forwarding stream (matching the sink name, or application.name = "EasyEffects"). Current EasyEffects forwards through direct PipeWire node links (ee_soe_output_level:output_* -> alsa_output...:playback_*), which never appear as PulseAudio sink-inputs at all. The scan finds nothing, so the script falls back to returning easyeffects_sink itself -- exactly the case the header comment warns about: "the display moves while the speakers do not".

Verified live: during active playback through Easy Effects, pactl list sink-inputs shows only the apps playing into easyeffects_sink; no EasyEffects stream toward the physical sink exists.

Fix

EasyEffects persists its configured output device in ~/.config/easyeffects/db/easyeffectsrc ([StreamOutputs] outputDevice=). When the stream scan finds nothing and the selected sink is easyeffects_sink, read the physical sink from there:

• validated against the live sink list (pactl list sinks short), so a stale/unplugged device falls through to the existing fallback unchanged
• complements the existing EasyEffects stream matcher -- setups where the forwarding stream does appear keep working exactly as before
• works whether or not audio is currently flowing (the node links only exist during playback; the config is always there)

Reproduction

# Easy Effects running, Process-all-outputs on, default output = Easy Effects Sink,
# EE output device = speakers, autogain (or any dynamics) in the chain
omarchy-audio-output-sink
# before: easyeffects_sink          <- virtual sink, wrong target for volume
# after:  alsa_output...Speaker__sink  <- physical sink

omarchy-audio-output-volume +5
# before: OSD moves, loudness unchanged (autogain normalizes it)
# after:  loudness actually changes, easyeffects_sink untouched

Verification

Case	Result
Default = Easy Effects Sink, playing	resolves to physical speaker, keys change real loudness
Default = Easy Effects Sink, idle (no links)	same, via persisted config
Default = physical sink (EE off)	unchanged (early return)
Missing/stale easyeffectsrc	falls back to previous behavior
omarchy speaker-tuning filter chain	unchanged (stream scan runs first)

Tested on Omarchy 4.0.1 with Easy Effects 7.x, PipeWire/WirePlumber.
