I upgraded my Odroid C2 with the latest L9 image and everything went smoothly, with the exception of some audio issues and reconnecting my bluetooth remote control (that's another story). At first I had no sound, however through some setting changes I managed to get audio for all files, with exception of those with 2.0. I have a 5.1 setup and the audio is passed through to my new AV receiver (Marantz SR6013). The only way I can get sound for 2.0 files and live tv is to tick the stereo upmixing option.
In my L8.2.5 installation I didn't have the stereo upmixing ticked and I got stereo pass through. Has anyone else found this issue with L9 and Odroid C2?

Audio Output Device: HDMI
Number of channels: 5.1
Output configuration: Best Match/b>
Stereo upmix: Enabled (only way to 2.0 audio)
Normalize levels on downmix: Disabled
Resample quality: Medium
