Or a WWV receiver.

USB Audio worked for me on the NET4801 with Linux. Unfortunately the
FreeBSD USB Audio support is less than complete.

I have found one Mini-PCI audio card (the Cromwell MP-787S based on the
ALS4000 chipset which is supported by the sbc(4) driver) and have
ordered it. Once it arrives we'll find out if it works.

Did I have problems installing FreeBSD on the Soekris? Yes. It was a
less than trivial installation of an OS with which I don't have much
Was I able to use a USB Audio adapter with FreeBSD? No. The FreeBSD USB
Audio driver does not support the input channel on the Griffin iMic.
Do I find the NET4801 to be unsuitable as an NTP server? No. It is
working quite well for me.
