If the guest incorrectly programs the lm4549 audio chip with a zero
frequency, we will pass this to AUD_open_out(), which will complain:
A bug was just triggered in AUD_open_out
Save all your work and restart without audio
I am sorry
Context:
audio: frequency=0 nchannels=2 fmt=S16 endianness=little
The datasheet doesn't say what we should do here, only that the valid
range for the freqency is 4000 to 48000 Hz; we choose to log the
guest error and ignore an attempt to change the DAC rate to something
outside the valid range.
