Not at the moment but how is it going to be related to spdif? I do not need HDMI audio at all.
Sorry, I forgot that HiFiBerry has to be selected as LE's audio output device. Selecting PI: HDMI and Analogue or PI: Analogue will deactivate this DAC, but should activate the analogue jack of the RPi.
I assume you have been followed the official instructions. If this doesn't solve the problem, ask the HiFiBerry support. They are pretty firm.
If it turns out that it's impossible to have both outputs at the same time, then maybe an RC button switch is an option for you.
