• Dxtory video/audio codec questions

Just recorded some footage with Dxtory after trying several times with different codecs and I ended up using MagicYUV which all looks fine: https://www.youtube.com/watch?v=r103c9Y8Eqs However, I noticed it didn't record any sound? Even though Dxtory was set to 16bit PCM at 48000 Hz? I know it did record sound when I used the Dxtory codec, but that was incompatible with Handbrake and Avidemux. I've been trying now for 4 hours to solve this, recording like 30 times or so(that was for the video codec, would either come out laggy or take up too much disk space), just can't be bothered to do it all again for the audio. Any help appreciated.
I haven't used Dxtory much recently, but judging by the audio tab, it seems you need something like Stereo Mix in order to capture desktop audio. Stereo Mix is basically a virtual recording device by Realtek that mirrors whatever is playing through Realtek's Speaker output device (so you'll also need to set that as the default device). This is usually disabled by default, so you'll need to go into the Audio control panel to enable and use it. If you don't have Stereo Mix or if it doesn't work, you still have more options. For instance, you can use the local recording feature of OBS Studio to record video that automatically records desktop audio. You can insert Dxtory output as a video source in your scene. It might not be raw quality, but for most cases it's good enough.
Well that might be the problem, under audio device it was set to digital output. Weird though, I didn't change anything under the audio tab and it sure did work the first time I tried Dxtory with it's own codec.
Yeah for it to capture audio all the time you need to use either your audio output or stereo mix, stereo mix will 100% work but it will record all your audio so if someone is spamming you notifications on something, those will get picked up too. Personally when I just want to capture game audio, I use VB Cable as you can then output the game audio to just that while still having it then output to your speakers etc after by just telling windows to listen to the device on another audio channel. As for video codec, look into UTVideo, its an amazing lossless codec with very little overhead, found it works with Dxtory really well. You can also alternatively use x264 but you've gotta mess with it to get the configuration just right, plus I've found it doesn't play well with all versions of Dxtory, sometimes it'll work then it gets updated and suddenly its causing video distortions and straight up file corruption. That and its more of a resource hog than the lossless codecs as they're essentially just near-raw video with minimal compression whereas x264 is doing full encoding on the fly (still much better than most other codecs, you just need to spend a lot of time with it to get it just right, once you nail the settings to something your system likes, you can get it to a level where its got as much overhead as the lossless codecs but it still produces a much smaller file at the same quality).
