Post [SOLVED] NI Komplete Audio 2 - alsa only and no output

EDIT: All workin fine with alsa only,
however I suspect it was actually earlier too,
I had a loopback/dmix in .asound.conf which it does not like..


So got a new NI audio device since old trusty HDSP Hammerfall device started to act up, either Firewire card or Interface is busted.
I ran it without a poweradapter for a long time, maybe it's the cause of misbehavement lately.

However the NI has issues, I get no sound out in both Reaper or term even tho it's recognized, I can select it, but I get no meters feedback or sound thru it.

Suspecting so far it's either a old kernel or wrong usb version or
simply need to go with jack2 again ontop..
More test will follow when new PC is up and running.

If anyone is running it successfully please pitch in

NI states device is class compliant on forum
Gathered some info so far.

Default

Your kernel version is older than the audio device, so maybe try a later kernel first to see if it has proper support for the device.

There have also been updates to ALSA and PulseAudio in the last year. Perhaps some of those would help this issue, if it's not solely about the audio driver in the kernel.

Generally I'd recommend installing an updated distro.
