 * **Show remaining time** no longer reticks the seekbar width every second — fixed-width playbar clocks stop `WaveformSeek` resize/redraw jitter; clocks sit tighter against the waveform with an inline duration toggle icon.
 
 
+### Linux — instant play/pause/seek/volume on PipeWire
+
+**By [@Psychotoxical](https://github.com/Psychotoxical), reported by PHLAK, PR [#990](https://github.com/Psychotoxical/psysonic/pull/990)**
+
+* On some PipeWire setups, play, pause, seek and volume changes only took effect after a long delay (10+ seconds). Root cause: the PipeWire ALSA bridge negotiated a multi-second audio buffer, so changes were only heard once it drained. Psysonic now caps that buffer, so the controls respond immediately.
