No I just installed CoreELEC on a sd card and connected the lead. The volume is quite low I must admit.
My M1 is connected to a computer screen through HDMI7
My audio output is set to ALSA: Default (AML-M8AUDIO Analog), PCM
Hmmm bummer. Sounds like the same as me. I just have it hooked to a receiver instead. Maybe I'll try change the setting again.
Matt, does your analog output work?
