To deliver DRM-protected content, Flash calls several functions provided by the HAL daemon and its libraries. While Flash-based players remain popular, HAL has been deprecated and is not commonly installed on newer systems. To provide the necessary HAL functionality on such systems, you can either install the full HAL package and run the HAL daemon or install a modified HAL library 'stub' that uses the modern UDisks daemon instead.

You may also wish to enable the daemon at boot, either by adding '''hal''' to your '''DAEMONS''' array in /etc/rc.conf (if using sysvinit), or by running '''systemctl enable hal.service''' as root (if running systemd).

As an alternative to installing all of HAL, you can install a modified version of the libhal library from the [[Arch User Repository|AUR]] that uses the modern UDisks daemon instead of the deprecated HAL. Note that this libhal provides just enough of the HAL functionality to meet Flash's needs for copy-protected delivery: if you have other programs that require HAL, this stub probably won't satisfy them and you should use the full hal package instead.

Since the libhal stub passes its calls to UDisks, UDisks should be running before you attempt to play DRM-protected Flash videos. To verify udisks is running using systemd:
