I have recently put together a new Threadripper build. Audio from the rear panel works, but I am unable to get any audio from the front panel. The motherboard I am using is the ASROCK TRX40 Creator which has the Realtek ALC4050H+ALC1220 audio chipset on board. Since this motherboard/CPU is relatively new: information about them seems to be fairly sparse online. PulseAudio lists the following information for the card:
index: 2
name: <alsa_card.usb-Generic_USB_Audio-00>
driver: <module-alsa-card.c>
owner module: 3
properties:
alsa.card = "3"
alsa.card_name = "USB Audio"
alsa.long_card_name = "Generic USB Audio at usb-0000:47:00.3-5, high speed"
alsa.driver_name = "snd_usb_audio" device.bus_path = "pci-0000:47:00.3-usb-0:5:1.0"
sysfs.path = "/devices/pci0000:40/0000:40:01.1/0000:41:00.0/0000:42:08.0/0000:47:00.3/usb9/9-5/9-5:1.0/sound/card3"
udev.id = "usb-Generic_USB_Audio-00"
device.bus = "usb"
device.vendor.id = "26ce"
device.vendor.name = "Generic"
device.product.id = "0a01"
device.product.name = "USB Audio"
device.serial = "Generic_USB_Audio" device.string = "3"
device.description = "USB Audio"
module-udev-detect.discovered = "1"
device.icon_name = "audio-card-usb"

I would expect the front panel and rear panel to be listed as separate ports, w/ the front panel showing as "available: no" if it were disconnected. Furthermore `lsusb` shows a S/PDIF output for this audio interface, but that doesnt show up at all in PulseAudio's output. In `pavucontrol` this all manifests in the output having no dropdown to select different physical ports for the card. The other thing that stands out to me is this device is detected as a "generic" sound card.
One last curiosity is that the system lists an audio controller under `lspci` as well, however I don't see that interface *at all* on the PulseAudio side of things. The "Generic USB Audio" listed above does indeed output to the rear IO panel, so I have no idea what this PCI card is.

I have the same issue on Ubuntu 18.04 and CentOS 8.1, and it seems the problem is being fixed here for kernel 5.6 and upper.
