Thanks that helps!
So a couple things, your OBS looks like it's missing a core file in the install directory (unless this is by design on WIN8 but I don't think so), you may wish to try reinstalling it: Looks like you are missing the following :
1. You won't lose your scenes or profiles if you reinstall over your current installation. Just download the latest version again from the site and reinstall, make sure you run the installer as administrator, although it should automatically.
2. Second your sampling rate doesn't match your devices, go to the Audio settings and change OBS to 48Khz and restart.
3. Also depending on what you are capturing application wise, it may be problematic as you have two GPU's, OBS is loading on the Intel, but if you using the NVidia for a game or application,. and then capturing that across then into the Intel (where OBS is doing it's work) things will have some delays and hitches as the bus will be busy with lots of moving and copying, this could also affect your audio due to DPC interrupts etc.
4. I'm not sure on your particular model of laptop how to set the GPU for use for each app, usually there is a control panel tool to do so and tell it to use the Nvidia for your application/game as well as OBS, keeping them on the same gpu will be beneficial. Also I don't know if it is as important on Win 8 to run the app as administrator but typically it is always best to be running OBS as administrator (right click and run as administrator on OBS Icon).
Do 1 and 2 and 4 as is easy and fast, and see what your results are, then to further improve do #3 and report back, once that is working can instruct on how to install Coreaudio-Encoder to improve your audio quality...
Let us know and send a new log with a stream/recording attempt after those are completed to see the changes. Good luck!
