The kernel is happy with the sound card.

ALSA believe that there are two audio systems: a motherboard
audio jack and a video-card HDMI that can play audio that way.
Here's a laptop that I have:
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: VT1802 Analog [VT1802
Analog]
Subdevices: 1/1

card 1: AUDIO [SMSL USB AUDIO], device 0: USB Audio [USB Audio]

You can see that it has a first set of jacks, an alternate set,
an HDMI output, and a USB-attached sound card (DAC).

Capture is for the recording side. That's normal.

Those are almost certainly on/off controls for the various HDMI
outputs. Do you really have 10 physical HDMI or DisplayPort outputs?
I would say your problems are related to PulseAudio and mixer
controls. Most likely PulseAudio is trying to send sound via one of the
HDMI outputs, or it's otherwise confused about where to send audio.
