1.6.7
Fixed 8
- Fix a scheduler regression where some driver nodes would not run correctly and cause sync issues
- Fix a race issue with suspend on samplerate changes that can cause ports to be silent
- Fix locking issues in the RT portal by reducing the DBus timeout and disabling portal RT for pipewire and the pulse server
- Fix potential incorrect delay in combine-stream
- Fix a regression in ALSA period_size calculations for non-power-of-2 periods
- Fix a potential segfault when removing a card because of bad ALSA api usage
- Emit a route param update when card properties change to ensure jack port updates are reflected correctly
- Make sure we don't deal with uninitialized spa_dict
PipeWire 1.6.7 (2026-06-18)
This is a bugfix release that is API and ABI compatible with the previous 1.6.x releases.
Highlights
- Fix a race issue where some ports would stay silent after a rate change.
- Fix sync regressions between ALSA cards in some cases.
- Small fixes and improvements.
PipeWire
- Fix a scheduler regression where some driver nodes would not run correctly and cause sync issues. (#5210)
- Fix a race issue with suspend on samplerate changes. It can cause ports to be silent. (#3547)
Modules
- There are some locking issues in the RT portal, for now reduce the DBus timeout to something more sane. Also disable portal RT for pipewire and the pulse server. These are not usually run in a sandbox and can go directly to RTKit.
- Fix potential incorrect delay in combine-stream.
SPA
- Fix a regression in ALSA period_size calculations. For non-power-of-2 periods, it would in some cases round down a a power-of-2, causing a mismatch between requested and configured period_size. (#5302)
- Fix a potential segfault when removing a card because of bad ALSA api usage. (#5255)
- Emit a route param update when card properties change. Otherwise, jack port updates are not always reflected correctly.
Misc
- Make sure we don't deal with uninitialized spa_dict.
