We just recently had the same problem. The rub comes from analog vs. digital we are told at Best buy where we bought our sony and there is no really good fix. The HDMI converters are not the answer we were told, we just have an outdated sound system. I bought a 3.5 mm Mini-to-RCA stereo audio cable that is placed into the headphone jack and then in the bose system in the TV jacks. A $10 fix. Works OK, not exactly the same quality but definitely acceptable for stereo only, not surround sound. This will be what we use until the Bose bites the dust
