When recording with oCam, you may sometimes encounter problems with sound recording. In particular, when a DAW (Digital Audio Workstation, for example FL Studio) program using Asio4all is running, it may take exclusive control of the system audio, making sound playback or recording unavailable in other programs. As a result, normal sound recording in oCam may become difficult. Below is a detailed explanation of how to solve this problem and record smoothly with oCam.
Asio4all is a driver used for low-latency audio processing and is mainly used in DAW programs. However, when Asio4all is enabled, it takes exclusive control of the system audio, so other programs such as oCam may not be able to capture system sound. To solve this problem, you need to change the audio output device in the DAW program to something other than Asio4all.
The following is how to change the settings:
1. Run the DAW program (for example, FL Studio).
2. In the case of FL Studio, click 'Options' in the top menu, then go to 'Audio Settings'.
3. In the 'Audio Settings' window, check the audio output device and change it from Asio4all to 'Primary Sound Driver' or 'DirectSound'.
4. After saving the settings, play audio in the DAW and then try recording with oCam. The system sound should then be recorded normally.
If you must use Asio4all because of latency issues with a MIDI keyboard, it is best to switch the settings flexibly depending on your working environment. For example:
- When producing music or doing MIDI work in the DAW, use Asio4all to maintain a low-latency environment.
- After finishing your work and when you want to record with oCam, change the playback device in the DAW audio settings to 'DirectSound' or 'Primary Sound Driver' to disable Asio4all.
- After changing the setting, restart the DAW, or reboot the computer if necessary, then confirm that the setting has been applied properly before starting recording with oCam.
Using this method, you can resolve the audio exclusivity issue caused by Asio4all and record system sound smoothly in oCam. If you are working in a DAW and recording at the same time, try switching the audio output device according to the situation to maintain the best environment.

How to Fix Audio Coming from Only One Speaker During Microphone Recording
When recording microphone audio with oCam through a professional audio interface, the sound may not be recorded properly because of issues that differ from those of a standard microphone. In particular, when using an audio interface, problems can occur because the microphone input is handled as mono (a single channel). Below is a detailed explanation of how to resolve this issue and important points to keep in mind.
When recording microphone audio through an audio interface, you may encounter a problem where the sound comes from only one speaker channel, such as the left or right side. This happens because of the way the audio interface handles mono input. To fix this, you need to adjust the microphone input source setting in oCam. Please follow the steps below:
1. In the oCam main window, click 'Tools' in the top menu, then select 'Options'.
2. When the Settings window opens, click the 'Sound' tab in the left menu.
3. In the 'Sound' tab, find the 'Microphone Settings' section and check the 'Input Source' setting.
4. If the microphone audio is heard only from the left speaker, change the input source to 'Input 1 (Left Channel)'.
5. Conversely, if the microphone audio is heard only from the right speaker, change the input source to 'Input 2 (Right Channel)'.
6. After saving the settings, try recording again and check whether the sound is recorded properly.
Notes
- In general, microphone input is mono, but in the case of inexpensive standard microphones, even if the physical input is mono, the software may process it as stereo, with identical data on the left and right channels. However, microphones used with professional audio interfaces are handled as mono both in the actual input and in software processing, so you must explicitly set the input source as described above for proper recording.
- If the microphone audio is heard only from the left speaker and you set it to 'Input 1 (Left Channel)' but no sound is recorded, while it records normally when set to 'Input 2 (Right Channel)', the left and right speaker channels may be physically reversed. In that case, you should check whether the physical speaker positions have been swapped or whether the left and right inputs of the cables connected to the audio interface have been reversed. For example, the speaker cables may be connected incorrectly, or the output settings of the audio interface may be reversed.
With these settings, you can record microphone audio properly in oCam even when using an audio interface. If the problem continues after changing the settings, it is recommended to also check the audio interface driver settings and connection status.
