i have a h/p laptop running vista home. i run free roll poker games and have a timer on this machine, and i display it on tv,s through out the bars. i use a svideo cable for the picture and plug into headset jack for the audio. all was fine then all of a sudden no audio, tried different cables and different tv's nothing changed. only thing i can come up with is i updated vista with the sp-1 package,dont know if this is just a coincedence or not. sure could use some guidance
