When booting up Fedora11 64bit on my Thinkpad T61, I cannot get any sound out of the machine. Booting into my 32bit Fedora11 partition has sound working just fine. This is with up-to-date pakcages from the Fedora 11 repos as of Jun 12 2:45pm EST.

Holy crap...didn't realize that looking at 'alsamixer -c0' that there were additional knobs if I just keep scrolling to the right (there's 14 knobs in total). Sure enough, a knob named "speaker" was muted, and un-muting it now lets me hear sound through the built in speakers in 64bit.
