There's a display issue if the screen resolution is too low ; some
elements do not appear. This is fixed in trunk/0.25 or if you're using
the 0.24 from this fork:

But with ALSA;default, you usually won't be able to use digital audio.
After you press the Scan for Audio Devices button ; move the cursor to
the "Audio Output Device" tab ; and read the description. It will
contain the word "analog".

You can manually set it because you have typed manually the name of
the audio device instead of selecting it in the list: so you're now in
manual mode. You want to only use the entries automatically detected.

If you want digital audio, you must select either the
ALSA:iec958:something or the ALSA:hdmi:something ; those are the only
two type of audio devices supporting digital passthrough
