Recently I formatted and reinstalled XP with SP2 (original version) in my pc. But I noticed there is no sound coming from internal speaker. Not from media player, windows system (sound of start, exit, error - it is enabled), or from web (youtube, google video, or any music site). But if i connect my head phone there is sound coming.
I went to the HP web site and installed the Multimedia / audio driver files (sound max).
By the way my system is HP dc5100 MT. I have a USB voip telephone connected to pc and it is working.
How can I solve this problem. Please help me.
