Followup of fc627e04d3 and ebc31cfbee. Since 2026-05-13 (or the day before) there is a single failure with the linux testbot VMs showing: ``` dsound.c:330: Test failed: DirectSoundCreate() failed: 8889000a ``` I could this reproduce inside a minimal Debian bookworm VM, after stopping pulseaudio: ``` systemctl --user stop pulseaudio.service pulseaudio.socket ``` Is there a better way to detect alsa not being able to open multiple times, and base skipping the test on this?
