Full realtime kernels (RT_PREEMPT) may provide slightly better realtime audio than a PREEMPT_DYNAMIC/preempt=full kernel, but the PREEMPT_DYNAMIC kernel should be perfectly adequate. As a point of reference, current versions of Ubuntu Studio uses a PREEMPT_DYNMAIC/preempt=full kernel, and the maintainers of Ubuntu Studio consciously chose to not install an RT_PREEMPT kernel. If you are having problems with intermittent audio dropouts that occur very infrequently, you may want to try an RT_PREEMPT kernel instead. The pre-built Ubuntu RT_PREEMPT kernel can be installed using `apt` but is only available if you have an Ubuntu Pro subscription. Ubuntu Pro is free for non-commercial use.

It's easy enough to reconfigure Ubuntu Server to run the Network Manager network stack instead. However you should be
aware that Netplan TCP/IP configuration settings will not be migrated to Network Manager. If you perform this step on a server on which changes have beeen made to Netplan configuration files, you will lose those configuration changes, and will need to reimplement them in Network Manager. If you are
a Netplan configuration (or are working with a clean install), then the default Network Manager configuration will work perfectly well too. On a clean install, or for ordinary
home use, switching network stacks is pretty low risk.

To reconfigure Ubuntu Server to use the Network Manager network stack (and therefore enable PiPedal's Auto-Hotspot feature), run the following command:
