The two configuration sections below are a good place to start in order to get the most out of Rocksmith 2014:
Rocksmith Audio Configuration
The first option is Microphone settings, which allows you to enable or disable your microphone for singing along with the game.
Rocksmith Audio Configuration (Advanced Mode)
Rocksmith INI File Details
There are two major sections to the Rocksmith.INI file. The first controls the audio settings of Rocksmith 2014:
EnableMicrophone [default: 0] - Set this value to 1 to enable the use of voice microphone. This is duplicated in the Rocksmith menus.
ExclusiveMode [default: 1] - Set this value to 0 if you want to have other audio programs running at the same time as Rocksmith 2014. You may need to increase your LatencyBuffer setting to avoid audio issues if you choose to disable Exclusive Mode.
LatencyBuffer [default: 4] - This value allows you to adjust one of the audio buffers used in one area of the Rocksmith 2014 audio engine. A smaller value will use a fewer buffers. Fewer buffers mean lower latency, but increase the demands on your PC to avoid audio crackling. Most recent high performance PCs can handle a setting of 2. The fastest PCs might be able to run reliably at 1. This value only supports whole numbers.
ForceWDM [default: 0] - Set this value to 1 if you've tried the fine tuning configuration options and still cannot get good audio latency or have audio issues you cannot resolve. This will force the game to use the previous Windows mechanism to control your audio devices. It can impose higher latency than the default system, but is a good fallback.
ForceDirectXSink [default: 0] - Set this value to 1 if you've tried all other configuration options and still cannot get good audio. This forces the game to use an old Windows mechanism to control your audio devices. It will almost always impose high latency, but should allow you to run the game. Use this as your last option.
DumpAudioLog [default: 0] - Set this value to 1 if you need to send debugging information to Ubisoft. It will create a text file called audiodump.txt, located in the same directory as the Rocksmith application. Once you have run the game with this switched on, be sure to set the value back to 0. Leaving the audio log enabled can degrade performance so leave it set to 0 for normal gameplay.
Win32UltraLowLatencyMode [default:1] - Set this value to 0 if you're having trouble getting the game to have good audio performance. This will drop the game back to the original Rocksmith audio settings and may resolve some audio crackling issues at the cost of some of the Rocksmith 2014 latency improvements.
MaxOutputBufferSize [default: 0] - A few audio devices have been found to have very large output buffers. In this case, the game does its best to choose a reliable audio buffer size. However, you might find that setting this variable will help to resolve audio issues. In its default setting of 0, it leaves the configuration of this value up to Rocksmith. Most audio cards end up using an audio buffer size of 1024. Fast PCs can usually run with this at 512. If you have disabled Exclusive Mode, you may need to use a higher setting for this. We haven’t run into any specific issues regarding the choice of values for MaxOutputBufferSize, but you have have better luck using multiples of 8 or 32.
