Waves 1.7.2 build 20

Waves 1.7.2 build 20 restores per-app control with Wave Link 3 and fixes Live activity reporting.

Fixed

• Keep playing Wave Link-controlled apps in Live by tracking Core Audio playback
  separately from route ownership.
• Remove terminated Wave Link-controlled apps from Live immediately.
• Omit parameters on parameterless Wave Link requests so Wave Link 3 accepts
  the connection handshake and channel listing instead of returning Invalid params.
• Preserve mix assignments, per-mix levels, and mute settings when moving apps
  to independent channels. Leave apps in place when a safe match cannot be verified.
• Match Wave Link's whole-percent volume steps so dragging a slider does not
  report a false read-back failure.
• Explain when an app's dedicated channel has not been added to a mix.
• Add setup and troubleshooting guidance in Mixer settings and Help, including
  shared channels, silent output, connection failures, and diagnostics.
• Stop flagging a full set of dedicated channels as a setup problem.
• Exercise the real server's rejection of null parameters in the loopback tests.

Independent app volume still requires a dedicated Wave Link software channel.
Apps sharing a channel, such as Zoom and Slack, must be separated in Wave Link.

Verification

The universal macOS package is Developer ID signed, notarized, and stapled. The application passed 691 tests, Thread Sanitizer checks, and local and hosted package verification. The release-policy checks passed 119 tests. Wave Link use was confirmed on the Mac mini.

The release owner approved deferring fresh performance comparisons, macOS 15 runtime testing, and the full physical Stream Deck matrix for this release. These checks are recorded as deferred in the attached publication evidence. No performance improvement or complete physical Stream Deck validation is claimed.

Requires macOS 14.2 or later. Supports Apple Silicon and Intel.
