[linux-audio-user] Alsa troubles? Why O why??

Hi everybody, Been on linux for about 1 year now. Realy super experience after my headache-period with M$. But I ran into troubles now... Reïnstalled my MDK 9.0 (different partition usage). At initial startup (before installing extra software) ALSA works fine, no troubles at all. After I installed the software, after a needed reboot, if I want to open my "alsamixergui" I get an error: no mixers found... No sound at all, even not running XMMS on OSS-out...I installed (almost) everything sound-related from mirrors I got from PLF. Did check soundcard settings, seems some program changed the driver for my SBlive to audigy.... (weird to me) Tried applying the old driver. It worked for the OSS, not for alsa, nor for esound... (yes esound doesn't allow any sound either) and yes, I suppose the mixers are not set to 0.. although I can't check that... Why o why does this happen?? Already noticed that turning off my Evolution-usb-keyboard during rebooting was needed, because of probs with alsactl during boot... Could anybody plz give me a clue howto solve this prob? And in addition to this, does anybody feel like expaining to me why (even on my previous setup) rosegarden doesn't produce any hearable sound? (yes the vu-meters move when I play an added track, but no sound is heard, and yes, jack is running (as root, right?) THX Karel alias 'Moeflon'
