Starting the audio analyzer by default?

Hello!
I am doing an exhibit using rPi and QLC+. I have a microphone hooked to up to an rPi USB audio input device and I have it working great controlling the lights with great low latency. My problem is that each day when the entire power gets cycled and the unit boots up, the audio analyzer is not enabled by default. I have to walk out the trail.....log into it with my phone....and manually enable the Audio Analyzer widget. Is there a way to enable this automatically? Thx!
PS-I have an rPi running 3 different exhibits at my show. Everything is working with the typical beta-type glitches. I am using a "Solo Frame" on one exhibit to select one collection at a time for the different seasons, but there is a glitch where some of the RGB matrices misfire the first time and then work the 2nd time (I saw this problem discussed in another thread). Also, the webserver crashes repeatedly so I need to keep rebooting things.
Thanks and talk soon!

Things also crash repeatedly when loading a new project...
Wow, what a chinese torture puzzle this is! I have to log into the QLC+ webserver to manually enable the Audio Analyzer widget, then when I put my phone away QLC+ crashes. Then I have to reboot and do it all again. It happened to me 5 times in a row. I finally got it to work by enabling the audio widget, then shutting down my WiFi completely before closing my phone. It is still running (I hope).
I am NOT complaining. I know I am using bleeding-edge beta-type stuff here. I am just reporting from the trenches. Speaking of trenches, here is the Raspberry Pi / QLC+ drum controller in action. There is an XLR microphone cable coming out going to a drum and also XLR DMX cable going to the IP65 DMX lights...

(I will make a coherent writeup sometime soon for the show and how I am using rPi/QLC+.)

Hi there,
The crash when exiting web access should be fixed in the next version
The solo frame glitches too
As of now, it is not possible to have audiotriggers started by default. This seems like a nice feature to have, I'll try to work on it.
Nice green snow you have there
Cheers :)

David,
Thanks for your response! Is it somewhat straightforward to build from source so I could test the changes that you mention? I could do this on Sunday or Monday. I have built OLA from source many, many times for the BeagleBone Black, so there is a chance I could build QLC+ from source for the Raspberry Pi. Thanks!

Steve, you asked this question before and I already replied.
Building QLC+ on the Raspberry Pi image that I provide is no piece of cake.
Otherwise, if everybody could do it, I wouldn't have asked for a contribution.
Comparing OLA to QLC+ makes no sense at all. OLA doesn't depend on Qt5, doesn't do multimedia and moreover doesn't display any graphics.
The image I tailored is optimized to the bone to avoid wasting any Raspberry Pi resource.
If you are a GIT maniac and can't wait the releases that I provide, then:
After that, please don't come back here with performances issues.
Good luck.
Massimo,
Thanks for your response! Indeed I know nothing about QT, so thanks for clarifying. To me OLA and QLC+ are both lighting frameworks that can be run on embedded linux devices at boot-time. They both have a simple web interface that I dont really need because I tend to run my exhibits and installations headless and leverage hardware inputs and hardware outputs that are enabled by default. I am curious if your comment about "enjoy QLC+ on a X Server slow like hell" means that all of QLC+ will run slow OR only the webserver/visual portion will run slow...
Regardless, I am not trying to annoy you...sorry about that. I will switch over to using Arduino/Teensy solutions (with my DMX/RDM shield) for now and patiently wait for the next QLC+ rPi version to be released. (As more of a hardware guy, I was excited to program shows at a higher level in QLC+ instead of programming at the C level in Arduino.)
Thank you for all of the work that you do! Last night was the first night of our show and the feedback was overwhelmingly positive. At some point I will document the portions that are running with QLC+. As of last night it was 1/2 Arduino/Teensy and 1/2 QLC+ with rPi and one QLC+/laptop.
