TV sound D to A

[cygnus x1]

Hi All,
Looking for a IC or board to convert optical out TV sound to analog line level. Tried a cheap unit off of ebay, lasted 6 mths and took a dump. Think I could build something better if I new what chip to use.

Thanks

I also bought a couple of cheap optical or usb to RCA adapters a few years ago both are still working fine. Try another one.

So is there one with an "audiophile" chip set?

I thought you wanted cheap. If you want audiophile, buy any hi end DAC with optical inputs.

look at schiit web page...

This might be better value than the little black box DACs:
CIRMECH Optical coaxial audio decoder CS8416 CS4398 chip 24BIT192KHz SPDIF coaxial Optical fiber DAC decode board For amplifier|Digital-to-Analog Converter| - AliExpress
I'm not endorsing it, it just came up when I searched AliExpress for digital audio converter.

Any of the low cost converters only ever output 48kHz stereo. Whatever the audio format started out as, it will be resampled in the source device to 48kHz, 2-channel. The only way around that is to buy an expensive AVR unit. The problem has to do with encryption, DRM, and decoder licensing (which is only offered to big companies).

Beyond that issue, the dacs in those cheap converters are the cheapest, and most cheaply implemented, possible. For better audio fidelity, a converter with a 48kHz SPDIF or TOSLINK output can be connected to a higher quality dac with SPDIF/TOSLINK inputs for conversion to analog. Such dacs can be had for a few hundred dollars up to several thousand dollars. The best sounding ones tend to be expensive although high price is no guarantee of quality.

In other words, it's a moot point.

My thread with AD1862 DAC contains Optical to I2S board based on WM8804 chip (it is tested and works). Next you can build my audiophile AD1862 DAC, even with power supplies. All you need is basic soldering skills and a little determination. You can then compare the sound of this DAC with $$$$ devices. The most beautiful thing about it is, that you put it together yourself

Keep in mind that the comparison method matters.
