It also has a problem controlling the device:

Working onboard:

audioctl show-control -d /dev/sound/audiohd:0ctl
CONTROL                  VALUE
volume                   75
front                    75:75
headphones               75:75
speaker                  75:75
mic                      50:50
line-in                  50:50
beep                     75
monitor-gain             100:100
record-source            mic

Non-working HDMI:

audioctl show-control -d /dev/sound/audiohd:1ctl
CONTROL                  VALUE
volume                   100
Bad enum index 10 for control 'record-source'
