Motorola DCT6412 III- no volume control?? Help!

post #1 of 7
Thread Starter 
I am using a Motorola DCT6412 III DVR cable box via Time Warner to watch TV on my Olevia 32" LCD-TV. I'm using an HDMI cable to connect the two and I have good picture and audio.

However, the cable box has no control over the volume. ( It functions 100% correctly when using RCA cables for audio/video hook-up) The volume bar appears on the screen and is visually indicating that there is a change in volume, but there is no change in the sound level.

I have gone to the gray screen menu ( cable and tv on, power off cable box + hit "menu" button on cable box within 3 seconds) and tried the various audio settings but no luck.

Can anyone offer insight to this? I almost kicked both my tv and the cable box out the window in frustration.

After still messing with all settings I'm stumped. Anyone have any insight?

I don't think you can change the volume of digital sound outputs. I mean what would it look like? Bigger 1's and 0's?

Sorry to piggyback on your question but I have a question that's related.

My HD channel sound volume is really low. I have an Onkyo TX-SR575 receiver. I have fiber outs going into my receiver. For the analog channels, my sound output is fine. At volume level 18 it's nice and loud.

For HD channels tho, I have to turn it up to 30 or even higher sometimes to hear good volume.

I know the HD channels output in Dolby Digital, and some of my channels output in Dolby 5.1 surround.. but I thought the analog channels also output in Dolby Digital. It's a digital receiver so I thought all sound is converted to digital if it's analog.

I've tried every surround setting on my receiver and nothing really brings up the volume. Not even changing it to standard 2channel stereo on my receiver.

I have advanced sound turn on, matrix, and high compression. I've tried light compression and no compression and nothing changes. I don't even know what the compression setting is even doing because I don't hear a difference when I change it.

You're supposed to change the volume level on your TV, as that is where audio amplification is done. There is no volume adjustment for the digital output on the Motorola box.

Many STB/DVR remotes can be configured to control the volume on your TV or A/V receiver. If your remote cannot, then you'll have to use your TV remote or buy a universal remote.

Dolby Digital is only available on digital channels (SD and HD). Dolby Digital can be sent as 2.0 or 5.1. Analog channels use analog stereo which the STB/DVR must convert into digital PCM for output via optical or HDMI.

Different STBs and DVRs may not convert analog stereo (on analog channels) into digital PCM in the same way. Audio levels on analog channels may be very different on different model boxes.

Some receivers allow you to separately adjust the gain on PCM and Dolby Digital channels to better equalize the volumes on those channels. However, even then, different channels don't always encode their digital audio with the same levels, so some channels are still a bit louder than others.

so basically what you're saying is that I have to live with it?

sometimes I forget to turn the volume down when I turn it to a SD channel after being on a HD channel. man that sucks late at night when the old woman is in bed

What I'm thinking is my receiver can do dolby pro-logic II. basically simulating 5.1 surround. And it turns that on when I get 2channel sound.

Talked with someone at work who has the same cable company and same DVR box as I do. He has the same problem on HD channels.

Guess I'll learn to live with it even though I don't like it.

Don't know about that model but on the DCH you can go into the menu. Hit menu twice. Go to Setup. Audio setup. Audio output to advanced. Then play with the settings below and see if that helps. Can't remember what I set them to but this helped me with the same problem.
