How to capture video with audio in FLAC instead of AAC?
I know there's a command line options line in the Video Profile Configuration. It is unclear how that will work though. There is no information in the support help files. If I could turn on a debug mode or get some logs or something, that would get me started.

Well what do you know? The logs were easy to find. I put `-c:a flac` in the Command line options and it changed to audio encoder to flac.
To get it to successfully record a video, I had to define the video encoder too. The final string I put in the Command line options is: `-c:a flac -ar 48000 -ac 2 -c:v hevc_nvenc -pix_fmt yuv420p -preset slow -threads 0 -rc constqp -qp 13`
I like that it has the option to override what encoders are being used, but I don't love that I have to supply both audio and video overrides to get it to work.

The logs were easy to find. In the Audials install folder, go in the folder AppData, then LogConfig. Open the file Audials.xml. A few lines down it tells were the logs are stored. Mine says '${LOCALAPPDATA}\Audials\Audials 2025\Log\log.txt'. On Windows, AppData is a hidden folder, but I have Windows set to always show hidden folders and display file extensions—as everyone should. Either way, if you open a new folder and enter %LOCALAPPDATA%\Audials\Audials 2025\Log into the address bar, it will navigate to the log folder. There's a bunch of logs in there. I searched for ffmpeg in them and found the entries I needed.
To override the ffmpeg commands, open options. Pick Video Streaming Recording. Click customize. Make a new profile or edit an existing one. At the bottom under where it says command line options: you can put in the overriding command. For two channel audio and visually lossless video, I put in:
-c:a flac -ar 48000 -ac 2 -c:v h264_nvenc -pix_fmt yuv420p -preset slow -threads 0 -rc constqp -qp 11
