Public bug reported:
After a clean install of Hardy Alpha 6, and up through tonight's
updates, I have no audio.
uname -a: Linux noel-hardy 2.6.24-12-generic #1 SMP Sat Mar 8 01:30:36
UTC 2008 x86_64 GNU/Linux
dmesg is attached. You'll notice all of the problems during bootup.
The following details are probably superfluous, given the information
from dmesg.
The Gnome Volume Applet has the red strikethough, and double-clicking
results
No volume control GStreamer plugins and/or devices found.
If I go to System->Preferences->Sound, I see that everything that can be
is set to Autodetect. Clicking "Test" results in:
