@Toby Smithe There is no problem with my harddrive ;), see new attached dmesg attachment. I have unmounted 'everything' and turn speakers and volume control up, but the center and the rear speaker still not work. I know that the setup is correct before ubuntu, i used windows with the audigy sound driver and it works.
@Daniel T Chen I ve try any well me known options such as gxine OUTPUT 5.1 turn up every volume control in alsamixer and so on. Example Settings Amarok: Output Plugin : ALSA Device Config: Mono: default Stereo: default 4channels: plug:surround40:0 6channels: plug:surround51:0 So if you mean this is a user problem, tell me ;), but everything I try dont work. ** Attachment added: "DMESG new" http://librarian.launchpad.net/6496999/dmsg.txt -- Only "stereo sound" with SB Audigy LS with ALSA https://launchpad.net/bugs/86816 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
