[Jack-Devel] help for linux virgin

[Ralf Mardorf]

Hi Richard,

consider to subscribe to "Linux-audio-user -- A list for linux audio
users" https://lists.linuxaudio.org/listinfo/linux-audio-user and to
repeat your request, since this is the best mailing list for novices to
get the kind of help you need.

Mint isn't an official Ubuntu flavour, but it much likely does use most
packages from the official Ubuntu and official Ubuntu flavour
repositories.

There is a package search for the repositories,
https://packages.ubuntu.com/ .

Regarding https://www.linuxmint.com/rel_serena_cinnamon_whatsnew.php
your release of Mint seems to be based upon Ubuntu xenial (16.04LTS)
[1].

Since you installed qjackctl, the jackd package which depends on jackd2
or jackd1 already should be installed. A dialog should have asked you
to configure jackd, but lets focus on this after you subscribed to the
Linux-audio-user mailing list.

Just in case, you could install
https://packages.ubuntu.com/xenial/jackd2 or
https://packages.ubuntu.com/xenial/jackd1 after opening a terminal, by
running

  sudo apt update && sudo apt install jackd2

The pros and cons of jackd1 and jackd2 are unimportant at the moment,
as a starting point jackd2 is a good, but not necessarily the
better choice. It depends on a few things what version to chose,
however, there are reasons that jackd2 often is preferred.

Audacity has a few pitfalls, so it's better to use another app. What
app depends a lot on your needs.

First of all you should install

https://packages.ubuntu.com/xenial-updates/linux-lowlatency and
https://packages.ubuntu.com/xenial/rtirq-init , in other words, from
command line (a terminal) run

sudo apt update && sudo apt install linux-lowlatency rtirq-init

After installing the new kernel you need to boot the new kernel.

If repeat your request to the Linux-audio-user mailing list post the
command line output of

  lsb_release -a
  uname -rm
  id
  grep -v "#" /etc/security/limits.conf
  cat /etc/security/limits.d/audio.conf
  /etc/init.d/rtirq status
  grep RTIRQ_NAME_LIST /etc/default/rtirq
  aplay -l
  arecord -l
  amidi -l

Regards,
Ralf
