Help finding converter/adapter from coaxial to hdmi

[jebe68]

After 2 days of intense searching I decided to ask for help to find a clearly unusual, but imo not too strange solution:
to connect my DAP that has digital out, to an audio-system that has HDMI inputs only.

The DAP (iBasso dx180) has the option of switching the 3.5mm PO/LO/DO to Digital-Out, which seems best to keep the signal digital.
First step is by means of a (4-pole) 3.5mm mini-jack style plug, to RCA-style coaxial audio cable. That is a common cable, so far so good.

But then that Coaxial audio plug of the other end, needs to connect to a HDMI audio-input of my Sony HT-A9 home theatre sound system (I know it is not high-end, and certainly painfully lacking other connection options, but its music reproduction is surprisingly good). So I'm stuck with HDMI audio input only.

For the other way round there are numerous so called 'extractors' (to extract HDMI sound to coaxial/spdif etc). And also numerous other devices have a coax out. But there seems NOT ONE device anywhere that is: coaxial IN -> HDMI out. Well not anymore, as the 'Monoprice 105971 component spdif/coaxial/toslink to HDMI' converter on Amazon could, but unfortunately is not for sale anymore.

So please, if you know a solution/option/device, many thanks in advance.

Hi @jebe68! Welcome to ASR.

Look for "HDMI audio embedder".

There's one from Lindy, Aten, PureTools, Techly, KanexPro, Amex, as well as a generic design sold everywhere, including on AliExpress.

If necessary, then you can convert your DAP's Coax out to Toslink using a cheap Coax SPDIF to Toslink Optical converter.

Thank you for this swift reply, that might work through toslink optical.

I hope that the signal stays digital than through toslink optical? Im not very familiar with the tech-side of those signals, and wonder if that still would be in favor/better than the analogue line out option of the DAP?

Correct. Toslink only carries SPDIF digital audio.

If you'd prefer a direct Coax connection, Aten and Extron make Embedders with Coax in.

Tnx, this is much appreciated!
