I'm not sure if this is all part of the same problem but there are multiple things going on. On my laptop ( its an HP Pavilion DV6, with an intel core i3 CPU @ 2.20ghz, & 64 but operating system ) The only way i can get any sound to play is if I watch videos in my firefox browser. No sound will play when i use Chrome (which I prefer) or Itunes, or windows media player. The problem with watching videos in firefox is that there is about a 20 second delay before the video will play, and an error comes up to stop the plug in or continue. If you close out of that box the video will play but you will get the same delay every time it is paused and started again. Browsing in Chrome and playing videos from that browser there is absolutely no lag, its lightening fast, but you will not get any sound. Other simple programs ( Like solitaire) have the same lag, each card you click takes about 20 seconds for the move to actually take place. I've tried messing with my sound drivers to correct the audio issues but I am not sure if it is an audio issue, a flash player issue, or a combination. Any input?
