Just wanted to note that I had some success getting sound working in the chroot through alsa by using the instructions posted here for temporarily disabling pulseaudio: http://talk.maemo.org/showthread.php?t=37708



With this I've managed to record/playback audio in audacity from a chroot.

WARNING: Be very careful about speaker use when suspending pulseaudio, as the n900 uses a software equalizer in PA to prevent speaker damage. When running straight through ALSA (i.e. using pasuspender) this daemon WILL NOT PROTECT YOUR SPEAKERS FROM DAMAGE. Don't blame me if you blow a speaker, try at your own risk, etc....


I recommend low volumes and/or headphones when playing at this for now.
Also, keyboard in LXDE is still not working for me even after copying the chroot changes and installing qole's listed packages.
