Hi Andy,

I have pulled your changes and installed the modules. The playback
pausing issue is now gone. As you noted there is an issue with the
first capture. I get no audio until I stop the capture and start
again. To work around this, I put a capture script in my rc.local to
"initialize" the cards.

Thanks again and have a great holiday!
