hdmi dummy dongle for hardware acceleration in headless mode

you can use this device to fool headless mode into thinking you have a screen plugged in. this is in order to trigger hardware acceleration that would otherwise be set to off, making a remote session painfully slow. this makes it much nicer to use!

ALSA vs JACK

pointandclicksystems — Sun, 09 Oct 2022 19:58:26 +0000

In my experience, alsa is adequate for multi i/o sound devices, and is generally what i use for all my programs. its hassle free and no frills. Jack tends to be a mystery when its not working and tends to boil down to rebooting a machine and setting it all up again. mysterious things happen with jack but it does offer a much deeper flexibility than alsa. some programs require jack such as renoise. so its good to know how to use it. youtube has a lot of videos from the entire emergence of jack onwards and is hard to tell what is relevant and what is outdated info. i find that if i immersed myself in the videos thing would gel and its the only reason i know what i do and can get as far as jack has allowed me lol! im no expert, but i can answer questions to the best of my understanding.

qjackctl is a utility i have installed that allows you to make changes and view connection diagrams etc. start menu > run > qjackctl

qjackctl jack configuration utility

This utility is where you make configurations to jack. Youll need this to run renoise or to aggregate more than one audio peripheral.

This utility is installed on my boot drive and you can start it by typing qjackctl in the run menu item of the start menu. There is plenty to watch on you tube about configuring jack using qjackctl. jack is finicky in my experience but patience does pay off. i have only tried to use it with my expert sleepers modules and a behringer sound card i have, both with success.

use separate thumb drive to save files

I highly recommend you save all files to a separate thumb drive so if you want to flash the new boot disk image, there is no worry of overwriting your project files.
