why dont hdtv's have rca audio out jacks for the general tv audio? i notice my father's 50'''''' hdtv has a digital audio out. i do know it is partly for higher quality, i'm guessing. it is also for having surround sound?

i'm trying to convince my father who is in his early sixties that it would be better for him to get a new speaker and reciever set. he has vintage realistics that were top of the line radioshack speakers at the time. they play great, i won't lie, still, but he's sort of determined he could get good audio if he got a converter box or converter cable with a digital audio out to rca jack. i think he's looking for the 3.5mm jack sort. i'm not too knowledgable on home audio but he is and has done technician work all his life, so i'm confused as to why he's being stubborn about getting updated speakers. i explained to him the quality and that it could go into surround sound.

we went into best buy and i guess he didn't believe me, because he was shocked to see most hdtv's that are around 32'''''' or so and above don't have rca and have the digital/optical audio out.

besides my questions i have asked are there other reasons for them not having rca jacks, too? i'm trying to convince him to get a new speaker and receiver set without having to spend hundreds on converter boxes or cables.

rca jacks were meant for stereo sound, 2 speakers and done, digital was designed for dvd and above sounds quality. multiple channels etc surround sound not just 2 speakers. if he wants to keep his realistics he can, he would still get better sound than the tv. im guessing you have a panasonic 50 inch plasma. he just needs to get a stereo receiver with a digital input that matches the tvs output. or if you want to keep it simple for him get him a sound bar with digital input.

as for why most dont have rca jacks, its simply because of manufacturing costs and the brand assuming you are going to use surround sound and not stereo sound.

its partly because of the surround sound thing and also maybe cost but i think the main reason is planned obsolescence...this type of marketing was started by the computer industry and is the way they get you to buy new equipment even though the older equipment may still be working perfectly fine...

the sound standard for all hdtv channels is 5.1.

why would you make a tv that can accept 6 speakers worth of sound, but then cripple it by putting only 2 speaker output jacks on it?

every connection on the back of a device costs $$ to design for and build. and most people do not want to run 6 separate sets of rca cables. this is why the digital connections were invented - to give you 1 cable to handle it all.

they have been making dolby digital receivers for fifteen years. you can pick them up for $90 on your local craigslist. these all have optical inputs that can take that tv output and drive those speakers.
