Public bug reported: I have a display connected to HDMI port and speakers connected to analog out. In gnome-control-center the sound device is set to "Analog Stereo Duplex". However, after the display was in standby mode, the audio is always sent to the HDMI output, so I have to change it back to Analog Stereo Duplex in gnome-control-center... This happens after installing linux-image-3.0.0-17.30 from oneiric-proposed, and I think it is related to the "drm/i915: HDMI hot remove notification to audio driver" patch. Old kernel 3.0.0-16 works well.
