Additional information for this bug: - On the affected system (kernel 7.1.13+deb13-amd64 from backports, Debian 13) snd_hda_intel runs with power_save=10 and power_save_controller=Y. There is no local configuration setting these (no TLP, no modprobe.d options, no udev rules): they come from the new kernel defaults (power_save_controller defaults to on since kernel 6.15, IIRC).
- Timeline: audio worked fine with kernel 6.12.x; the intermittent failures started right after upgrading to kernel 7.1.8/7.1.13 from trixie-backports (mid-September 2026). - I am now testing 'options snd_hda_intel power_save=0 power_save_controller=N' as a mitigation for the suspend/resume variant. The login race (GDM greeter PipeWire vs user session) is unaffected by this and still needs the restart workaround.
