Digital Audio Out and headphones problem with volume control

Dec 9, 2017 8:44AM PST

I have a Sanyo DP32242 32" and I bought the Digital to Analog Audio Converter, cheap headphones, and an RCA Coaxial cable (pics below).

I have everything hooked up right I am certain, as I can turn down the TV and hear in my headphones. But I cannot control the volume in the headphones and it is way too loud.

I want to purchase bluetooth speaker(s) because I do not want to wear anything in or on my ears. But unless I can understand what this volume control issue is, then I don't want to purchase anything else (more expensive) yet.

I did read of a situation where the external device (headphones etc) had a volume control, but it still didn't turn down the volume.

My question is, have I got all I need to make this work, and does anyone here have the same or similar issue, and solved it?

Thanks in advance for any help.

PS Can't I do an "upload" attachment here? I can't get the URL to the photo of my parts off Flickr, no URLs.

Avoid getting fancy with the Insert Image or URL tools. Just paste the link. Folk will look.

That out of the way, optical audio is digital and not volume controlled. This is done for reasons too long to get into here but it means that the volume control is done in the audio decoder, headsets or speakers.

-> Since this is how optical audio is supposed to be, there is no reason to solve it.

Now if you want volume control, you have to get that feature in your external devices.

One more question and thanks for the explanation, it helped.

Ok, makes sense. Although the "read" I did about the guy that had an issue with controlling the volume with his external device hadn't been answered on another forum. So is there a reason, with "my" TV and the setup I have, that an external devices volume controls might not work?

I'll go ahead and post the "weird" link for my pics, just copy paste, hope they work if someone wants to look at them.

Thanks much for your info, it was helpful.

I see you can insert pictures.

But what is that other discussion?

That aside let's tackle " an issue with controlling the volume with his external device ".

The devices you show do not have volume control so you end up with fixed volume levels. Again, optical just outputs the digital signal so it's up to the decoder or receiver to do the volume work.

If you already bought these things, you can consider a headphone volume control like this one:

I understand, I'll look at the link you gave me, and go for speakers that have those capabilities. I do appreciate your help. Out of 4 different forums, you are the only one that truly had the knowledge on this issue, thanks so much.

Suggestions on speakers?
Dec 9, 2017 10:27AM PST

I saw the links, but I do want to get speakers. I think I can find them with the right technology, instead of the cords in the links? I really don't want the headphones, just bluetooth speakers that I can sit on each side of my chair. Or I see many of those are just one speaker which should be ok. Just rather have 2.

Almost all Bluetooth speakers are
Dec 9, 2017 11:09AM PST

Stereo connected to each other (wired) or in a single unit. I will not at this time suggest "true wireless" Bluetooth earphones or speakers as the Kanoa meltdown is still ringing in my ears and memory. Long story about that but for now there are companies that will sell you broken systems like the Kanoa. Video at https://www.youtube.com/watch?v=36Gw3tErUSM

So https://www.amazon.com/gp/bestsellers/electronics/3236451011/ref=pd_zg_hrsr_electronics_1_4_last does speaker solutions but not all have Bluetooth.

I own a set of Satechi speakers with Bluetooth. Seem fine too. https://smile.amazon.com/gp/product/B00GMREIKS/ but they may be unavailable plus no remote.

Yes, by the way, on the attachment photos. When I plugged in those "long" codes they just turned into pics, lucky I guess.

Ok, so I'm in your "bookshelf speaker" link and it will just be up to me to pick the right set.

Thanks so much, really. I know know what I have to have to make this workHappy

I have to ask you one more question, R Proffitt, I promise
Dec 9, 2017 12:03PM PST

just one more.

Will these work for me. Something in the description threw me, so I wasn't sure. It says "Works with Bluetooth enabled devices and any device with a 3.5mm input including a computer, television, smartphone, tablet and music player"

So is it saying I need to hook them to bluetooth enabled AND the any device..?

Thanks much, I feel I'm almost there, lol!!

Those Logitech speakers don't have Bluetooth.
Dec 9, 2017 12:09PM PST

So this means you missed that or didn't need Bluetooth after all.

When you zero in on what you really want, just post again.

Yes, I missed it
Dec 9, 2017 12:50PM PST

I thought they did as I did the search for Bluetooth Bookshelf Speakers and those came up.

I do want Bluetooth so I have to search again.

Yes, I missed it. That's why I come to people I believe can help me. If I could figure everything out myself, and not miss things, I wouldn't need tech forums. And you'd be out of a job.
