Bob,
Yes, that also worked just fine. The only problem remaining is my
volume plugin for gkrellm does not come back up with my controls
enabled: After every reboot, I have to reconfigure the plug in to have
volume sliders for Master, PCM, CD, etc etc. This happens if I
blacklist it or set alsa priority to -2
