Now mplayer ebuilds have +rtc in IUSE, which is completely nonsense. From man mplayer: -rtc (RTC only) Turns on usage of the Linux RTC (realtime clock - /dev/rtc) as timing mechanism. This wakes up the process every 1/1024 seconds to check the current time. Useless with modern Linux kernels configured for desktop use as they already wake up the process with similar accuracy when using normal timed sleep. $ mplayer -rtc -rtc-device /dev/rtc0 /usr/share/sounds/KDE-Im-Phone-Ring.wav MPlayer 1.1-4.6.3 (C) 2000-2012 MPlayer Team Failed to open /dev/rtc0: Permission denied (it should be readable by the user.) $ ls -la /dev/rtc* lrwxrwxrwx 1 root root 4 Jul 9 07:03 /dev/rtc -> rtc0 crw------- 1 root root 254, 0 Jul 9 07:03 /dev/rtc0 mplayer2 ebuilds have rtc disabled, mpv devs removed it: https://github.com/mpv-player/mpv/commit/614f847516b7ed98784b8d491a417e037ff2f391
