* CPU frequency scaling daemons that scale the frequency of the CPU depending on the CPU load could cause xruns in some cases. More recent versions of Jack1 (>= 0.118.0) are suffering less from xruns or run xrun free with a CPU frequency scaling daemon enabled that's set to a scaling governor like ondemand. A specialized CPU scaling daemon is in the works that depends on the DSP-load instead of the CPU load: [[http:// | * CPU frequency scaling daemons that scale the frequency of the CPU depending on the CPU load could cause xruns in some cases.

* Desktop Environments (DE): especially on less powerful machines it is recommended to use a lighter DE than Gnome, KDE or Unity. Possible alternatives include LXDE, XFCE or IceWM. Another option is to only use a lightweight Window Manager (WM) like Openbox or Fluxbox. | * Desktop Environments (DE): especially on less powerful machines it is recommended to use a lighter DE than Gnome, KDE or Unity.

* Gnome NetworkManager and WiFi: NetworkManager keeps scanning for new wireless networks in the background and this might cause xruns. The best option is to not use a wireless network manager in a low-latency real-time audio environment. If you really can't do without WiFi you probably won't have another option than to use wpa_supplicant. | * Gnome NetworkManager and WiFi: NetworkManager keeps scanning for new wireless networks in the background and this might cause xruns.

- | * NTP: there are reports of NTP interfering with FFADO, so if you're using a FireWire audio device make sure you disable the ntpd service and any cronjob or ifup script that tries to sync your local clock with an NTP server. This issue is resolved in the 2.1.0 release of FFADO. | ||
