Applications trying to play sound seem to hang. But I can play sound with no problems if I send it directly through oss (with "ogg123 -d oss", for example). pulseaudio complains that the es1968 driver may be buggy, but I have no way of knowing whether the bug is really in alsa or pulseaudio. I've used this sound card for many years under alsa without any problems. This was a clean install of Karmic.
