Funny you should mention! I have been playing with the 2.6 test 9.4 kernel, and have noticed it even more. I have 9.2 Cooker (2.4.22-21mdk) , which is really just 9.2 since the freeze has been on. This is a desktop with a Turtle Beach Santa Cruz card (cs46xx), 5.1 Dolby Digital to a kickin' set of Altec Lancing speakers / subwoofer. I _can_ rattle the window! but that is another story. I'm all ALSA. I can stream 128k audio off the net with no problems, but I have some oggs that get funky and choppy, but not always. No lockups at all. There are some issues with gstreamer-alsa based players, and ChangeLog shows fixs have just released. I've played with a bunch of music manager software - it is uses gstreamer I have a serious sound problems; if it uses xmms, then the minor issue mentioned, if it uses alsaplayer, smooth as silk.
