I have an HP 2000 and occassionally when I connect my comp. to an HDMI cable the sound only works on the computer
not the TV and then I have problems with sound when watching videos on computer alone or with headphones. I also
have got an error message from webpage saying that something is null and then says line 1530 and I have to reboot to
get away from the error message. I have checked all updates for the audio.
