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!
