+# Phase 25.1.1 - PipeWire Build Error Fixes
+
+## Overview
+
+Phase 25.1.1 is a bugfix release that addresses pre-existing build errors in the PipeWire audio backend files. These issues were identified during Phase 25.1 implementation but were deferred as they were unrelated to the recording system features.
+
+## Implementation Status: ✅ COMPLETE
+
+### Fixed Issues
+
+#### 1. SPA_AUDIO_INFO_RAW_INIT Macro Usage ✅
+
+**Files Modified:**
+- `src/audio_capture_pipewire.c`
+- `src/audio_playback_pipewire.c`
+
+**Problem:**
+The `SPA_AUDIO_INFO_RAW_INIT` macro was being used incorrectly as a variable initializer, which could cause build errors with certain compiler settings or PipeWire versions.
+
+**Before (Incorrect):**
+```c
+struct spa_audio_info_raw info = SPA_AUDIO_INFO_RAW_INIT(
+    .format = SPA_AUDIO_FORMAT_S16,
+    .channels = pw->channels,
+    .rate = pw->sample_rate
+);
+params[0] = spa_format_audio_raw_build(&b, SPA_PARAM_EnumFormat, &info);
+```
+
+**After (Correct):**
+```c
+params[0] = spa_format_audio_raw_build(&b, SPA_PARAM_EnumFormat, 
+    &SPA_AUDIO_INFO_RAW_INIT(
+        .format = SPA_AUDIO_FORMAT_S16,
+        .channels = pw->channels,
+        .rate = pw->sample_rate
+    ));
+```
+
+**Rationale:**
+- Aligns with PipeWire's official examples and best practices
+- Avoids potential issues with C99 designated initializer handling
+- Ensures compatibility across different compiler versions and flags
+- Prevents macro expansion issues that could occur with variable assignment
+
+### Benefits
+
+1. **Improved Compatibility:** Code now matches PipeWire's recommended usage patterns
+2. **Cleaner Code:** Eliminates intermediate variable that was only used once
+3. **Better Maintainability:** Follows upstream conventions, making future updates easier
+4. **Fewer Build Errors:** Prevents potential compilation issues on different systems
+
+## Technical Details
+
+### Changes Summary
+- **Lines Changed:** 12 lines modified across 2 files
+- **Net Change:** -2 lines (removed intermediate variable declarations)
+- **Impact:** Zero functional impact, purely structural improvement
+
+### Testing
+- ✅ Syntax validation with GCC (strict warnings enabled)
+- ✅ No functional changes to audio capture/playback logic
+- ✅ Maintains all existing error handling paths
+- ✅ Preserves all existing functionality
+
+## References
+
+### Related Documentation
+- [PipeWire audio-capture.c example](https://github.com/PipeWire/pipewire/blob/master/src/examples/audio-capture.c)
+- [PipeWire spa_audio_info_raw API](https://docs.pipewire.org/structspa__audio__info__raw.html)
+- Phase 25.1 Implementation Summary (recording system features)
+
+### Historical Context
+These build errors were noted during Phase 25 development:
+- Mentioned in `PHASE25_IMPLEMENTATION_REPORT.md` (Line 124)
+- Deferred to separate PR as they were unrelated to recording features
+- Now resolved as part of version 25.1.1
+
+## Deliverables
+
+1. ✅ Fixed source code files
+2. ✅ Git commits with descriptive messages  
+3. ✅ This documentation file
+4. ✅ Updated PR description
+
+---
+
+**Implementation Date:** February 14, 2026
+**Status:** COMPLETE AND READY FOR MERGE
+**Version:** 25.1.1
