Bit of a weird one this.
Running XBIAN on a Pi 2, hyperion has been working great with LED's but about 2 months ago, i formatted the SD card and reinstalled from scratch.
Hyperion is installed and configured fine, using hypercon to test the lights work fine. Using stop/start, the light do the colour wheel all fine, but watching movies, the lights seem really subdued now.
Prior to the reformat and reinstall, the lights reacted fine to anything I played via Kodi, so i'm a bit stumped as to what the issue could be, especially since the tests etc seem to work fine. (although I am seeing a "cannot connect to server" from the Android hyperion test app as well?)
Any help appreciated!
(edit - just uninstalled and reinstalled via hypercon, and now no lights working at all - argh)
