If you check the manual for these monitors, I think this would explain the phenomenon you're experiencing: > Standby > > Your monitors have the ability to power down when you are not using them > for 30 minutes.

Generally speaking, if you're hooking up devices that expect line-level audio signals to a consumer PC audio card, you'll want to set the volume level of the output to between 75 and 100%, then adjust the volume controls on the speakers themselves to achieve a comfortable listening volume. This will help reduce interference / cable noise as well. --Sean _______________________________________________ pulseaudio-discuss mailing list pulseaudio-discuss@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss
