> do you mean this patch still not fix your problem ? I'm not a developer, so all I can say to the patch is that the description seems to fit. If this patch is present in the pulseaudio package which shipped with ubuntu 14.10 then this patch did not fix the problem.

Functionality of the Subwoofer channel can be temporarily restored by switching the audio profile from 5.1 to stereo and back to 5.1 again. Changing the line in /etc/pulse/daemon.conf from ; enable-lfe-remixing = no to enable-lfe-remixing = yes Fixes this issue permanently with my current hardware configuration. ubuntu-bug wrongly identified the Nvidia HDMI port as the symptomatic card. The actual playback device is the build in Intel HDA ALC1150 audio chipset.
