So I had this "tanix tx6 mini" laying around, i put the tx6 image on SD card to try it and it's working really great, especially hd audio, truehd and dts-hd are playing perfectly on my avr. Thanks to the team.
I have one little problem though with the remote, I can send the device to sleep or power off using the menu and I tried both KEY_POWER and KEY_WAKEUP in my key table (build from scratch and i also used with success the tx3 mini template), but these two keys won't work and I have to deal with the power ac adapter on the back of the unit to power on, this is not really practical indeed.
Hope someone will be able to help or give me a direction. Thanks in advance.
