-# [S] Audio device tests pass on ARM
-
-## Goal
-
-`just rs audio-devices` passes on the hosted ARM runner, as it does on
-x86_64 Linux, so its nightly lane is a signal rather than a known red.
-
-## Plan
-
-The recipe first ran nightly on 2026-10-20 and failed all five playback
-tests on ARM; nothing owned it
-([moq-dev/moq#6155](https://github.com/moq-dev/moq/pull/6155)).
-[moq-dev/moq#6175](https://github.com/moq-dev/moq/pull/6175) then fixed
-PulseAudio's 20 ms playback period for these tests.
-
-But Nightly
-[39600361153](https://github.com/moq-dev/moq/actions/runs/39600361153)
-(2026-10-21, before #6175 merged) already passed all five on
-`ubuntu-24.04-arm`, after the 2026-10-20 failure, with no moq-audio change
-between. So a green nightly alone does not prove #6175 fixed it: the failure
-may be intermittent. Decided 2026-10-22 (maintainer): delete this quest only
-after three consecutive green Nightlies on ARM; on another failure, reproduce
-on ARM and fix the cause, not the timing.
-
-Public API: none. Wire: none.
