usb soundcard not working

I am using a Creative Sound Blaster Play! 2 usb sound card. As far as i understand the card is set up properly, but it is not producing sound.

$ cat /dev/sndstat
Installed devices:
pcm0: <CMedia CMI8738> (play/rec)
pcm1: <NVIDIA (0x0016) (HDMI/DP 8ch)> (play)
pcm2: <NVIDIA (0x0016) (HDMI/DP 8ch)> (play)
pcm3: <NVIDIA (0x0016) (HDMI/DP 8ch)> (play)
pcm4: <NVIDIA (0x0016) (HDMI/DP 8ch)> (play)
pcm5: <Realtek ALC889A (Rear Analog 7.1/2.0)> (play/rec)
pcm6: <Realtek ALC889A (Front Analog)> (play/rec)
pcm7: <Realtek ALC889A (Rear Digital)> (play)
pcm8: <USB audio> (play/rec) default
No devices installed from userspace.

$ cat /boot/loader.conf

$ cat /etc/sysctl.conf

Where do I go from here?
I had a similar issue. You would want to use

pacmd set-default-sink 8
pacmd set-default-source 8

8 = the source number. There may be another work around but oddly enough this should work. The mic however may not work but ymmv.
