Troubleshooting a Realtek ALC662 With a Front Headset Jack
You’ve installed your new motherboard with the on-board Realtek ALC662 audio chipset, connected the appropriate cables to the right ports, installed your OS and set up your speakers, but when you press “Play,” there’s no sound or the audio just doesn’t sound right. Troubleshoot audio issues by checking the cables and connections first, and then make sure that the motherboard’s BIOS is correctly configured. If the hardware looks good, check the system setup for driver or configuration issues.
