Comment 18 for bug 363892

I also have a 1420n and was experiencing intermittent problems with sound (it would work in about 1 out of every 5 boots). I am running latest Jaunty as of around 2009-04-20 9:45am PST.

I found that the following fix: https://bugs.launchpad.net/alsa-utils/+bug/315809/comments/7 to the file /usr/share/alsa/init/00main results in sound working for 100% of cold boots. I am unable to get any sound at all after a suspend/resume though.
