I have 2 AMD Athlon 64 x2 computers, not absolutely identical but close, both running Mint Debian (LMDE) 201012. One of them plays sound in all applications and the other only plays sound in Gnome Mplayer. Not in Rhythmbox, Movie Player, Mplayer, flash on Firefox etc. The "good" computer shows the sound card in Pulse Audio Manager Devices but the other only shows "Dummy Output". I assume that this is because it isn't detecting the sound card at boot.
I've Googled the problem and there seemed to be a similar problem in Ubuntu Hardy but it seems that later kernels should have solved this. But not for me. Any ideas anybody?
