Hi, as I wrote in previous post I tried with a live distro (partedmagic) and everything works fantastic.
Well did you tried it with an actual siduction-live-iso? (never heard about parted magic)
Not tried to change backend,
Test this first.
but I had installed jack previously for an audacity recording session, using stereo line-in and not digital. Eventually I reverted all config to digital-out. At first didn't see any malfunction.
Nevertheless, you are maybe catching the right point: I think I have a horrible mixture of gstreamer, alsa, pulseaudio and jack.
So, besides "apt purge jack", or "dpkg --reconfigure [alsa|pulseaudio]" what else should I clean in your opinion?
THX
Never used 'dpkg --reconfigure alsa/pulseaudio', but long time ago i made my own alsa-config to use two audio cards (an usb one and the build in one, yes that is possible)
Now it should automagicaly work™ with pulse. Don't ask me how or if

I used to use jack a time ago with pulseaudio and had no problems (testing a synthesizer), but i don't have a soundblaster card and for recording i use my zoom-h5 device connected via usb or stand alone.
Btw. for professional recordings there a much better tools

.
And did you tried to use the build in "stock sound card"?
You have to choose, if you want to use alsa (the old fashion style with own config) or use pulse audio but not both at the same time.
So boot a "siduction-live-iso", test it and if it's works take a look to the manifest file and grep for pulseaudio and alsa and use the found packages as your standard and remove all other unneeded ones, that i meant with start from zero, and if this is to much work, install the iso and you have a virgin system with a working audio card.
That's all i can say, sorry i cant help you, i am not an audio-linux-freak and i only can give you some hints to look for, like Geier0815 did!
