Hi As Paul mentioned in another post, the kernel version for 7.x uses different devices for the audio/headphone output and HDMI, and so will only show the HDMI devices if the Pi thinks it's connected to an HDMI display. After having selected HDMI and rebooted, I wasn't seeing anything still, since that Pi is connected to the HDMI input on an amp, and that amp doesn't tell connected devices that HDMI is there unless the right input is active on the amp, and the monitor is on. So, I selected the right input on the amp, turned the monitor on, and hey presto, I see the Pi bootup process when I restart and the HDMI device is available as an output. Then, adding the lines to config.txt forces the Pi to always think there's a display there. So, if you're not seeing anything, do you see the Pi bootup processes etc. on the hdmi display, and is the device there when the whole display chain is active? pete S ------------------------------------------------------------------------ psketch's Profile: http://forums.slimdevices.com/member.php?userid=56555 View this thread: http://forums.slimdevices.com/showthread.php?t=113512 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
