What to Do If the Sound Becomes Louder or Distorted When Playing Recorded Videos in PotPlayer
When playing a video recorded with oCam in PotPlayer, the sound may sometimes be different from the original recording or become distorted. This may be caused by PotPlayer's Normalizer setting. Below is a detailed explanation of how to disable the Normalizer setting so the original sound plays back as it was recorded.
To disable the Normalizer in PotPlayer's Preferences, follow these steps:
1. Run PotPlayer.
2. Open the Preferences window. To do this, press the F5 key on your keyboard, or right-click on the player screen and select 'Preferences' from the menu that appears.
3. When the Preferences window opens, click the 'Audio' category in the left menu, then go to the 'Normalizer/Reverb' submenu.
4. In the 'Normalizer/Reverb' settings, check whether the 'Use Normalizer During Playback' option is enabled. In most cases, this option is enabled by default.
5. Uncheck 'Use Normalizer During Playback', then click the 'OK' button to save the setting.
After applying this setting, PotPlayer will no longer automatically amplify the sound, so the original sound recorded with oCam will play back as it is.
Note: What is the Normalizer feature?
The Normalizer is a feature that amplifies the playback volume to match 0dBFS (decibels full scale). For example, if the original sound was recorded at -20dBFS, the Normalizer amplifies it closer to 0dBFS so it sounds louder. However, if the sound is amplified too much during this process, it may become distorted or crackle. The dB used here does not mean ordinary decibels (dB), but rather the dBFS unit used in digital audio environments.
By disabling the Normalizer, you can play back videos recorded with oCam while preserving the original volume and sound quality. If the sound still has problems, check PotPlayer's other audio settings, such as the equalizer or volume control, or review the recording settings in oCam.

BIOS and CMOS Error Messages and How to Fix Them
โถ BIOS ROM Checksum error
This error appears when there is a problem with the ROM that stores system information.
It occurs when there is an issue while reading the information stored in CMOS. In this case, enter CMOS SETUP and check whether each setting is configured correctly for the current system state.
After completing the settings, select 'SAVE AND EXIT SETUP' to save the changes.
If the system is old, the ROM itself that stores the BIOS information may be damaged. In that case, it is recommended to have it inspected at a motherboard repair shop or service center.
โถ Press [F1] to continue
This message usually appears when the keyboard or mouse is not connected properly.
Please check whether both devices are connected securely to their connectors.
It is also a good idea to check whether the hard disk information is set correctly in CMOS SETUP.
โถ CMOS memory size mismatch
This error occurs when the system cannot properly recognize the memory (RAM).
When new RAM is added, CMOS usually detects it automatically, but in some cases the correct memory size is reflected only after running CMOS SETUP.
Enter CMOS SETUP, check the settings, and then reboot the system.
โถ NO ROM BASIC
This message appears when an error occurs during booting.
It usually occurs when the system cannot boot from drive A. In this case, you need to insert a bootable floppy disk into drive A or change the boot setting to boot from the hard disk drive.
Similar error messages include 'Diskette Boot Failure' and 'Invalid Boot Diskette'.
โถ CMOS display type mismatch
This error occurs when there is a problem with the graphics-related settings in CMOS.
It happens when the graphics type in the 'Video...' item in CMOS SETUP is not set to EGA/VGA.
Since this is the default setting used by most graphics cards, please make sure to check it.
โถ Cache Memory Bad..
This indicates a problem with the cache memory installed on the motherboard.
Cache memory is used to improve system speed, and on some motherboards, this error may appear if the cache memory fails.
In this case, you can replace the cache memory or try setting the cache memory usage option in CMOS SETUP to 'Disable'.
The same symptom may also appear when cache-related settings such as 'Cache Write' are configured incorrectly, so please check those settings as well.
