The new function writes a runtime state file to track the system volume following setting.
- New Features
- Added `write_runtime_system_volume_following_file` to persist system volume following state.
New Features:
- Added command-line option for system volume following and a background thread that polls the default audio sink volume
- Integrated the polled volume multiplier into playback volume calculations
- Introduced new runtime states and flags for system volume tracking
Enhancements:
- Replaced scattered printf debugging with standardized LOG_ERROR/DEBUG/WARN macros
- Pre‑read all runtime states before spawning threads, simplifying the main loop
- Detached the poller thread to run continuously without blocking the main loop
Bug Fixes:
- Extended argument count validation to accommodate the new flag
- Updated thread creation error logging to use LOG_ERROR instead of fprintf
- Fixed potential race by initializing the volume multiplier before playback threads start
Replace numerous printf statements with LOG_* macros, introduce system_volume_following parameter, and improve error handling throughout the daemon.
New Features
- Introduce LOG_INFO, LOG_ERROR, LOG_WARN for unified diagnostics.
- Add support for system_volume_following when spawning child processes.
- Log detailed startup information instead of raw printf.
Enhancements
- Refactor start_children signature to accept the new parameter.
- Use strerror(errno) in error logs for clearer messages.
- Improve signal handling output and reload request logging.
Bug Fixes
- Correct error formatting for pipe, fork, chdir, and execl failures.
- Ensure proper handling of system_volume_following_str initialization.
- Replace daemon‑specific prints with appropriate log levels.
