Seems the Laptop uses an Nvidia-sound driver: Audio device: NVIDIA Corporation GF106 High Definition Audio Controller (rev a1)
..and this is the proprietary driver that comes with the graphics driver.
journalctl -xb | grep snd should give you an overview what is loaded during the boot process - and when.

from what I can tell both internal & external inputs are armed ..but there's no guitar to be heard until I start something like Audacity with a 'record' track launch. Even then it's pretty intermittent and unreliable. When I start jack though, THEN it starts to work much better.
By default your mic shouldn't loop back into your speakers as thats not what most people want, whether you can configure pulse/alsa to do this without another app I don't know. With Jack you certainly can, using Cadence makes this easier to configure.
I'm using one of these, the output should be as good as any so-called adio-interface and pluggable into the laptop mic jack
Not quite, It only does one part of the picture, which is providing a converting your guitar level signal to a line-in level. An Audio interface does a range of other things as well, the main one is it connects to your computer via USB (or Firewire) and provides an additional low latency sound card which you can configure buffer sizes etc to reduce the delay between sound going in from your guitar to sound coming back out through your headphones. Most PC sound cards aren't designed for this application and this time will be noticeable. Generally most good audio interfaces will also allow you to monitor what you playing in Hardware without going into the PC to again reduce the latency you hear. When I do what i'm guessing you are aiming to do (you didn't specify your goal) I connect an audio interface to my PC and then just use it with jack and leave my built in card using pulse, with Cadence you can also link pulse audio apps into jack pretty easily if you want to jam with something. Unfortunately I can't recommend a good audio interface for Linux I do most of my audio production with windows these days, but atm I'm runnning a Mic into an interface that half works as an overkill video conferencing setup. -- Simon Lees (Simotek) http://simotek.net Emergency Update Team keybase.io/simotek SUSE Linux Adelaide Australia, UTC+10:30 GPG Fingerprint: 5B87 DB9D 88DC F606 E489 CEC5 0922 C246 02F0 014B
