I updated from 10.04.1 (Lucid) to 10.10 (Maverick) and i am experiencing problems with my sound. When i manually change songs in rhythmbox, my subwoofer stops playing. When songs pass automatically though, subwoofer continues to play fine for a while, but sooner or later it dies out anyways, just it takes an hour or two of playing. Funny thing is that if i go to sound preferences and in hardware tab i switch to some other than 5.1 (which my system is) and then switch back to 5.1, it begins to play normally as it should again, but only until next manual song switch. Do you have any suggestions on how to fix this? I had no such problems with 10.04 so it's not something with my speakers or sound card - i am sure of it.
Another strange thing related to this. I had to plug my speaker jacks into different places than before update in order for speaker test to recognize speakers correctly.
