> This series introduces three interdependent modules for real-time audio processing:
> 1. `volume` (PATCH 1/3): Provides sample-accurate gain control utilities with support for:
>    - Linear and logarithmic volume scaling
>    - Multi-format handling (s16/s32/flt/dbl, planar/non-planar) [7](@ref)
>    - Runtime adjustment via player_volume/volume parameters
> 2. `mapping` (PATCH 2/3): Implements dynamic channel routing with:
>    - Configurable output mapping via `map_str` option
>    - Multi-output broadcasting with frame cloning to avoid data duplication
>    - Runtime reconfiguration through command API
> 3. `abufsrc` (PATCH 3/3): Integrates volume/mapping as an audio source filter enabling:
>    - Fade-in/out effects with sample-accurate timing
>    - Asynchronous frame request via `on_event_cb` callback
>    - Pause/resume with automatic fadeout on state transitions

Please come back when you (1) can produce a patch series that can be
properly applied and (2) have taken the comments I have made this
morning into account.
