Audio Hardware / Re: Pass-Through of Compressed Audio to Yellowtec PUC Lite DDC without Decoding
Last post by Boba -
To the best of my knowledge, USB audio, be is UAC1 oe UAC2 support only 2 modes.
One is of course linear PCM.
The other is RAW, mostly used for DSD.

A DAC (or its receivers) simply don't understand any PC audio format. You can't send FLAC, MP3, WAV, etc. to it as it simply don't have codec's onboard. All a DAC does understand is a couple of protocols e.g. SPDIF (linear PCM packed in a 32 bit word), UAC1 or 2 (PCM or DSD), etc.

The only thing that works to the best of my knowledge is decode any PC audio format to linear PCM, pack it in a protocol and send it to a protocol converter.

That's quite a bummer, I assume that trying to send a compressed source from a computer wouldn't work, then ?

Can I ask you if you'd know by chance any hardware devices that could send a compressed audio source with an AES3, SPDIF or coax output (or anything not USB) ? I tried from an old DVD player with an SPDIF output, but the output stream seemed to be decoded by the DVD player

foobar2000 started decoding DTS out-of-the-box by version 2. In 1.x it could not decode, so it would just pass it on.
2.1 though, did something to it. From changelog:
"Added an option to toggle additional decoding (DTS, HDCD, etc) during playback, so you can play DTS-WAV without decoding DTS."


I tried also with foobar2000 1.6 too, but the issue I had here was that either it couldn't read my AC3 or DTS (because foo-input-dts wasn't installed), either it could read it with foo-input-dts, but would decode my dts stream. Do you know if an audio file can be read "raw" without having anything decoded ?
However based on Roseval answer I'm starting to doubt my whole setup : if the USB from a computer wouldn't allow to have a stream passed through to a DDC, using foobar or another software would give the same result, woudn't it ?

I don't know if I did something wrong but I have a problem.

I merged the locale file tags to the JSON database like we talked in the wrapped post, and put the write tags to write to json.

The problem is that now every new artist that didn't have locale tag is from Spain. Even when the biography panel load world map continues to show Spain.

I checked and the locale last.fm tags are well assigned, and the new artist doesn't have any.

I delete the world map data from js_data and tried again and the same happened.

Audio Hardware / Pass-Through of Compressed Audio to Yellowtec PUC Lite DDC without Decoding
Last post by Boba -
Hello everyone,

I'm seeking assistance with finding and setting up a media player software that could pass-through compressed audio formats (such as AC3 and DTS) without decoding it, to a Yellowtec PUC Lite Digital-to-Digital Converter (DDC) connected to my computer via USB. I'm getting the audio stream from the AES3 out of the DDC.
I hope this is not a duplicata of another topic, I couldn't find any help regarding this specific issue I'm facing.
The Yellowtec PUC Lite I'm using comes with an ASIO driver. I've tried it already with several media player software without success
I managed to make it work perfectly with PCM audio, my issue here is only transmitting compressed audio formats without decoding it before.

Here are the details of my setup:
  • Yellowtec PUC Lite DDC connected via USB to my computer (USB IN) with AES3 OUT.
  • ASIO driver installed for the Yellowtec PUC Lite.
  • Windows operating system (Windows 10 Professional).
   
And the Media player softwares I've tried so far :
  • foobar2000 : I've found quickly that even if passthrough is perfect for PCM audio with ASIO (or WASAPI even), the foobar2000 keeps decoding my AC3 or DTS files, which is not filling my needs
  • VLC Media player : I tried with WASAPI and DirectX (since no ASIO was available), and I don't have any audio out of my DDC
  • Media Player Classic (MPC-HC) : with additions of  LAV Audio Decoder for bitstreaming, couldn't make it work neither
  • KODI : used an MKV with AC3 audio for this one, but I couldn't passthrough to my DDC, it had to be the default speaker
  • Winyl : can't load AC3 or DTS natively, I assumed any extensions would recreate the behavior of foobar2000 of decoding the compressed audio before doing a passthrough
  • JRiver : I've read here (https://www.head-fi.org/threads/jriver-media-center-21-ready-to-go.780652/page-6) that JRiver doesn't do passthrough so did not try too much with this one

Any advice or recommendations on media player software or alternative solutions that can accomplish this would be greatly appreciated.

Thank you for your help!
