[ubuntu-studio-users] ubuntu-studio-users Digest, Vol 163, Issue 4

hi list, hi Ross,

sorry for my delay. I have tried something in the meantime. Have
installed ubuntustudo-control and made some entries but without a
success.

Here you can see the entries, which was written in the so called
~/.config/jack/conf.xml:

<?xml version="1.0"?>
<!--
JACK settings, as persisted by D-Bus object.
You probably don't want to edit this because
it will be overwritten next time jackdbus saves.
-->
<!-- Fri Nov  6 20:11:46 2020 -->
<jack>
 <engine>
  <option name="driver">alsa</option>
  <option name="realtime">true</option>
  <option name="verbose">false</option>
  <option name="client-timeout">500</option>
 </engine>
 <drivers>
  <driver name="netone">

   <option name="dither">n</option>

</jack>

It differs from the entries, which i can see in the settings of jackd
itself.
The entry <option name="device">hw:SB,0</option>
should be USB Jack Master
and UR22mkII,0,0

I had stored it, but as you can see, the entries are the same as before
storing the changes.

I cannont see, that this tool ubuntustudio-control is a
really facilitation.

The messages I get, are these here:

Hope, these messages does help to find out, what is going wrong here.

I cannot find more information on how to configure a correct jackd-
setup with my hardware.

It would be really nice, if you could help to setup jackd.
