This suggests a code flaw in the ice1712 driver module triggered at the
time audacity begins to open the device for capturing audio.

You could confirm it by trying to open the capture device using a
simpler utility, such as arecord.  If you get the same result, then you
have nicely excluded audacity from the problem, and identified the
kernel driver as likely cause.

What I recommend ... check for a more recent kernel in whatever
distribution you are using.

What I would do if I knew I could rebuild the kernel ... check for
patches to kernel source directory sound/pci/ice1712 after verison
