Well, FreedomBox doesn't require ALSA. I've tested it with the emu10k1 OSS driver that comes with kernel version 2.4.22; I haven't tried a 2.6 kernel yet. And on my 266 MHz machine I used the cs4231 OSS driver that comes with the kernel. To narrow down the problem, try the following. First, start usound manually as explained in the README file. Then, from the freedombox directory, type the following: helpers/mplayer -ao usound http://www.freedombox.info/mp3/fb_talk.mp3 This will use the patched version of MPlayer that comes with FreedomBox to play an MP3 stream from the FreedomBox web site. Let me know if that audio is distorted. Matt
