Public bug reported: What happens — the AMD ACP SoundWire link carrying two TI TAS2783 SmartAmps fails to program transport params at boot/stream-prepare, throwing repeated "Program params failed: -22" and leaving the ASoC node in a bad state. PipeWire then busy-loops recovering the node, pegging pipewire/journald with no audio playing — measurable idle heat and power draw.

Some boots present as "SDW_SCP_BUSCLOCK_SCALE register write failed" instead. Two amps on one link appears to be the trigger.) Upstream — reported on the SOF kernel tree: https://github.com/thesofproject/linux/issues/5824 . No merged fix is pinned yet for this exact dual-TAS2783 ACP prepare failure. Active AMD ACP7.0 SoundWire area: TAS2783A driver thesofproject/linux#5510, related reports #5796 / #5620. Requesting investigation and, once a fix exists upstream, backport into the 26.04 7.0 kernel. Workaround in place — WirePlumber session.suspend-timeout-seconds=5 masks the PipeWire busy-loop, but the kernel-side -22 desync still occurs every few boots. Reproducibility — intermittent at boot, every few boots; once desynced it is reliably present until "systemctl --user restart wireplumber" or a reboot.
