On a Dell Inspiron 9400 with snd-hda-intel, I get the same problem. There is an interesting effect where from a fresh boot, the suspend/resume works fine. Sound works and everything is great. The problems seem to be after I have run Banshee using Gstreamer.
Note that I can happily run mplayer or flash videos with sound time and again and then suspend and resume apparently fine. Running sudo /sbin/alsa force-reload will enable Banshee to play audio again. At this point, Mplayer no longer works, with the warning: AO: [pulse] Failed to connect to server: Connection refused Could not open/initialize audio device -> no sound. -- [hardy] After suspend sound isnt working anymore https://bugs.launchpad.net/bugs/198218 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
