Hello friends, I have a desktop computer which is running on Windows XP operating system. The configuration of the computer is Intel Core2duo processor with Intel 965 motherboard and 2gb Ram. The motherboard has integrated Realtek HD sound chipset on it. Recently I have started facing some weird problem with my computer, Whenever I plug in the Headphones in the Back panel of the motherboard, it does not get detected. The Sound only works if the headphones are connected to the front panel. I checked the processes in the task manager which are running but the RTHDCPL process in not running in Task manager. Is my motherboard faulty? or is this because of some virus? Please help.
