I am trying to setup my receiver with my TV and Comcast cable box using HDMI cables (TV-OUT and HDMI-1) but for some reason I don't get any sound from non-HD channels. Am I missing something?? I've read through the manuals and ran through different settings and cant seem to figure out why the receiver doesn't pick up the audio from regular channels. I was thinking of using a different setup like running component cables with an optical for the cable box but I don't want to go through the hassle of buying more cables if there's an easier fix. Thanks!

Get a 4 in 1 hdmi switcher.

You MAY need an HDMI modulator to do that.

HDMI version is 1.3 in your receiver.The current version is 1.3b. I would suggest calling Pioneer cust assistance and see if there is a firmware update. Your unit has a 2 year parts & labor warranty. Their # is 1-800-421-1404 It sounds like a CODEC issue. Hope this helps

After days of frustration the real problem was with the cable box. It needed a firmware update. Following forum advice I disconnected the cable box power cord for a few minutes, reconnected it, allowed the cable box to reinitialize. Turned off receiver and TV. Turned TV back on and set it to HDMI connection, turned on receiver and all worked fine. Great picture and sound.( Needed to buy an optical cable to go from the cable box to the receiver to get sound from the speaker system. )--the dirtybird

Connect the HDMI outputs on your various components to the HDMI inputs on your receiver. Connect the HDMI output on the receiver to the input on your TV. HDMI incorporates digital audio, so no need to buy optical audio cables. If your receiver does not have HDMI inputs for all your components, you will need to make a choice. HDMI = Best, component video + optical audio = second best, S-video+ optical audio = third best

Had the problem. Turned out to be a defective hdmi port circuit board.

I had the exact same problem on a brand new Insignia 26 " LCD with DVD. Comcast tech was able to fix it by changing the Comcast box diagnostics. Here is what he did. Using the Comcast remote with the TV on - press power, cable, menu in that order. A comcast diagnostic srceen will appear. Select Additional HDMI options, then audio options. Change the audio options to L-PCM. Press power again to exit the diagnostics. That will fix it and you get to use the HDMI cable.

the avr-588 apparently cannot carry sound via hdmi - don't know why; just what i found out from the geek squad at best buy; solved the problem by connecting optical cable from cable box to receiver; be sure to change the input on the receiver for opt-2 (system setup >2 inputs) to correlate with tv

dojran,

nice gear. Without further information, i am going to describe the best setup possible with your equipment.

1. make sure the speakers are connected to the receiver and you can hear sound out of it

2. connect cable box to receiver via hdmi to receiver.Choose cable on the receiver or video1 etc. (if you are not using hdmi cables post annd i will walk uthruogh a non hdmi process)

3. connect a hdmi cable from thee receiver monitor output area to the tv hdmi input

4. connect the dvd player hdmi to the input of the receiver

to watch select the tv av mode to line up with the receiver and choose video1 for tv and dvd to watch dvds on the receiver.

good luck
