Question / Help Audio Delay issue (Front Mic)

Okay, so I have my capture card audio connected through my 3.5 mm front mic jack since my cap card sucks. Huzzah, this works and OBS recognizes the sound. The problem however is that there is a half-three-quarter second delay in the sound. I know this is a problem with OBS as I don't have this problem with XSplit. Was hoping someone could help me resolve the issue. I use video capture device, select my dazzle, and for audio input I select my front mic (I have also tried the directshow audio plugin, same delay). Xsplit has none, but I hate Xsplit. Furthermore there is some random crackling here and there I would like to get rid of, but I don't know if that is possible, I get it on Xsplit, and also if I mute the game audio I still get it, so not sure if that can be helped. If it can please let me know =).

Sometimes there is a delay with audio in the mic channel. This is due to an internal design flaw (which will be fixed in the future) -- the fixes are to either use "Mic QPC Timetsamps" in advanced, or use "Mic Sync Fix Hack", either one or the other. Could you try them out and let me know if that works better?

No, these did not work. I think the reason may be that I am still using my microphone in audio settings (so people can hear my voice), and then using the directshow plugin to have the PS2 audio play (which is delayed through the front mic).

Okay, you may just have to manually adjust the sync. You can do this with the "mic time offset" for the mic, or "audio time offset" if the audio is attached to a device. You can set the time offset both forward and back in time. If you need to set it back in time, make sure that you have enough "scene buffering time" in advanced so it can buffer that audio as well otherwise the audio will get cut off

I don't believe that feature was implemented into the audio plugin, so that might be an issue in this particular case
