Capture and playback now go through AudioCapture/AudioPlayback interfaces with two implementations: PipeWire, used for the system default and for every pw: device when a session is reachable, and Java Sound for the raw ALSA devices and other platforms. The PipeWire binding is FFM-based (PipeWireLibrary, PipeWireSession, PipeWireStream, SpaPod) and enumerates the graph's real devices, so each stream shows up separately in volume mixers. Lines are opened with a negotiated channel count instead of a fixed mono format: OPUS_MUSIC transmits the stereo capture as-is, OPUS_VOICE keeps transmitting the mono downmix so the pre-processing chain and VAD still see a single channel. Java Sound enumeration asks only for "a mixer that can capture/play" so the PipeWire and PulseAudio ALSA plugins are no longer hidden by their narrow format lists. The Java Sound classes are renamed to Desktop* to match what they now are, and JUnit plus a SpaPod round-trip test are wired into the build. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
