This is a very common problem with no real solution. If your TV can be programmed to accept separate audio from HDMI video on the same input, you can feed the audio through standard RCA cables. Unfortunately most TV's do not allow this. Alternatively run them into a stereo receiver. Buying high end HDMI cables will not help. Most people I know with this issue have bit the bullet & just used component video instead. The difference in quality is minimal.
