The only problem I’m having is running PulseAudio at boot without x11 because of how it handles it’s session management... but I’ll get the instructions together anyway... it sounds really good by the way :). Look for something in the next few days from me.

>> Good news, I have made it all work flawlessly!  There were a few tweaks that I had to make within pulseaudio in terms of some buffer values and the correct sample rate and boom, I have clean audio now without the use of OSS which means I can have an updated kernel!  While there are a few different moving parts, it's actually somewhat trivial.. I'll put together directions if anyone else cares lol...

Also note that there i an osspd-alsa but that doesn't work.. when I try that it causes the usb closed errors that I had posted in the other thread and ASL won't get past that point.
