Seems the Laptop uses an Nvidia-sound driver:
Audio device: NVIDIA Corporation GF106 High Definition Audio Controller (rev
..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
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
