Hi Fernando,

thanks for your kind help! :)

ok...I will give pulseaudio another try...(sigh)

Before I start...
If my memory serves me right...is it true, that X11 starts
automagically pulseaudio , if it founds it?

And if so: How can I prevent that?

Next problem is: that armbian offers a LOT of pulseaudio
related packages...any hint what I need to install as a
minimalistic solution (this is an embedded device with
far less resources and far less hoursepower...)?

And: What do I need to install on my GENTOO PC?

Thanks a lot in advance for any help!

Best regards,
Meino
