Five minutes in and I'm thrilled. I had one issue trying to broadcast to YouTube: when setting up a new connection, select Default Authorization and not RTMP. It kept requiring YT user/pass and I knew that wasn't right. Emailed support and less than ten minutes later they responded and the situation was resolved. Thanks!

I've used this now for a few weeks to stream our church service and have gotten positive feedback from people who have tuned in to the livestream. The only thing I would like to see is some indication of whether it is using the external mic or the built-in mic. I am feeding the sound to my phone from an aux port on our sound board and my Pixel 3a does not always detect the line plugged into the headphone jack as a microphone. So, the only way to tell is by monitoring the livestream on a separate device to see what it sounds like. It would be nice if there was some way to indicate which mic was being used for the audio. Or, a setting that forced it to use ONLY the external mic (rather than use external mic if available). Then, if I am not getting any sound level indication on the screen, I would know that it is not detecting the external mic. Thanks for the great app!

Thank you for the review! Regarding the source - please go to Settings -> Audio menu and play around with Audio source parameter. Some external devices may also need higher Sample rate (like 48000) so that's another thing to try in case of issues.

I use the Larix app to stream Bible Study service on Wednesday evenings. The reviews I read previous to installing the app were fantastic. The app worked great for a few of our evening services but unfortunately, this past Wednesday was terrible! The audio feature is fine however, this picture resolution was nothing more than a blur. No one could see me at all. The entire screen was blurry. This is an issue that as of now, I still can't resolve. Need help before our next service!!!
