I tried playing with
alsamixer (booting the machine with a LiveCD since OpenELEC has no ALSA mixer application) but all I can get is sound going out through the output jack. With Kodi I can use any HDMI link I wish as the main output but I have come to wondering if both sound hardware can interact...
Input is made through Intel HDA
Realtek ALC892. HDMI is an
Intel Haswell HDMI.
