Digital audio converter only converting analog.

by matt3965 / February 4, 2014 7:21 AM PST

Hi I am trying to add speakers to a sanyo TV, the only output is digital coax so I bought a cheap digital analog converter on EBAY. I watch the TV tuner (Time Warner) and a ruku hooked up with HDMI.
The Roku and analog tv channels put out sound but not the
cable digital channels, they are static popping noises, I used a simple red white rca cable from the tv to converter.
What are my problems/options.

With some thousand models made by Sanyo

I can only write to look around for audio settings. Try PCM, Stereo, etc. Do not try HD, 5.1, etc.

Try changing the sitting of the digital audio out on the tv.

If it's not on PCM, then change it to PCM and see if that would do the trick. Good luck.

The cheap ones don't always work

If you end up tracing it back to the converter being the issue, find a more reliable brand. Monoprice & Amazon sell some fairly decent rigs. Amazon user reviews can often be very helpful. Ebay is a huge crapshoot IME and O. Not worth the couple dollars you might save.

Thank you for the replys

Thanks for the help guys, there aren't a lot of audio settings only things like mild, dynamic ect.
I will try it on another device but it probably is a cheap converter,
I'll try returning it through EBAY.

Hold on a second- speakers?
by Pepe7 / February 4, 2014 11:09 AM PST

You are directly connecting speakers to the HDTV via digital optical? I'm assuming they are powered speakers. Which make/model, btw? And is there any sort of external Amp/receiver too(?)

Partial sucess
by matt3965 / February 5, 2014 7:43 AM PST

I do not yet have an amp, I hooked this into a headphone via L/R adapter for debugging and testing.
I found an audio setting "default audio" and this solved the problem, however I have to do this everytime
I turn on tv or change channel. The converter does seem to work though
Sanyo DP26640

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
