hi

i'm having a problem which makes my system nearly unusable at the moment:

it is not possible to have different audio outputs at the same time. the first process to make an audio output blocks all other processes. so if i play a flash video , afterwards mpd will give no audio output. if i start mpd first, flash will give no audio output.

i tried to install pulseaudio to work around that problem, but pulseaudio causes nearly all apps using audio to crash.

i've seen a lot of related problems but have not found a solution yet.
i was adviced to use jack and configure my alsa, but i have no idea how to start...i found some tutorials and guides but none of them was for my problem.

i'm thankful for any help
