Hi Lee,

Have you tried a different HDMI cable?

Have you unplugged the TV and then plugged it back in?

The above have cleared occasional problems I've seen with video signals. Maybe they'll fix your audio problem.

As for getting X to work with a new video card, you'll need to boot in recovery mode where you'll get the option to start X in failsafe mode which should give you more options to get X working with the new card.

HTH,
Helen
