Ok, I've been playing around with the beta. It think the obvious stuff has been reported.
However, when I went to fix the hideous sound issue with xmms, by running alsaconfig, I got:
Error opening terminal: rxvt.
I ran xterm -e alsacong .. but I got:
xterm: unable to open font "-misc-fixed-medium-r-semicondensed--13-120-75-75-60-iso10646", trying "fixed"....
That font is horrific, and alsaconf is not displayed correctly. It was very annoying to try to read through the garbage to get sound working well. I don't know if sound _is_ working properly, as there seem to be lots of options which I'm not familiar with. =)
I realise that the new kernel fixes the sound issue.. but perhaps this xterm issue remains?
