[ntp:questions] help with IRIG

Can someone give me a hand with getting IRIG working?

It seems ALSA has taken over and /dev/audioctl and /dev/audio0 are missing.

The machine I am using is a HP thin client with audio input in the form of a microphone input.

I have attenuated the input by 20Db, added a DC blocking capacitor and an Audio isolating transformer.

I can hear the IRIG when I turn the speaker up.

However the format of the clockstats file is completely different to that documented on the refclock 6 page so I haven't a clue what's going on..

Any suggestions?
