I recently bought a Creative Labs X-Fi Go Pro USB audio dongle for my
ExpoPC Slate tablet running FreeBSD 9.0. Unfortunately, while the
device is detected and playback works, recording does not. (It always
records silence.) The device is detected as shown below:

ugen1.5: <Creative Technology Ltd> at usbus1
uaudio0: <Creative Technology Ltd Sound Blaster X-Fi Go Pro, class 0/0, rev 2.00/1.71, addr 5> on usbus1
uaudio0: Play: 44100 Hz, 2 ch, 24-bit S-LE PCM format.
uaudio0: Record: 44100 Hz, 2 ch, 16-bit S-LE PCM format.
uaudio0: No midi sequencer.
pcm6: <USB audio> on uaudio0
uhid0: <Creative Technology Ltd Sound Blaster X-Fi Go Pro, class 0/0, rev 2.00/1.71, addr 5> on usbus1

(Curiously, this device does record correctly on my laptop with FreeBSD 7.2.)

Is there a particular USB audio device which is known to work correctly
both for playback and record on FreeBSD 9.x? Any recommendations would
be appreciated.
