I'm trying to get the pcmplay example on the Empeg developer site to work. When I run it I keep getting these errors:

ioctl(SNDCTL_DSP_SETFMT): Invalid argument

I have the source verbatim from the developer site but it's not working. What the heck is going on? format is set to AFMT_S16_LE

Any ideas?
