It'll be the wonky USB audio, I think--audio1. `audio0' is the HDMI which'll
work because there're no issues to be seen with either the hdaudio(4) driver
or with i915drmkms.

From the dmesg on the new HW (both in 9.1 and 10.1):

```
uhidev3: CSCTEK (0x0573) USB Audio and HID (0x1573), rev 2.00/80.07, addr 4, iclass 3/0
uhidev3: autoconfiguration error: no input interrupt endpoint
```

So I don't know if `audio1' will work in 10.1 either. FreeBSD also seems to have
issues with CSCTEK USB audio:

Caveat emptor!
