A:AnswerHi. What kind of cable remote? If you have a Directv one, you can control both volume and channels if you program the directv remote. Follow the instructions for syncing the remote. Hope this helps.
A:AnswerIt has an 1/8 stereo headphone jack but does not have any RCA outputs. I have an adapter from the headphone jack to L&R RCA going to a cheap receive and it lets me use the receive and speakers for sound.
A:AnswerMake sure your cable box is attached to your tv with an HDMI cable. It works with others but it affects some functions and sound if you use others
