So I guess you are saying that you don't have a solution for S/PDIF output to do DSD128 using DoP?

Are all S/PDIF limited to DSD64 using DoP?

Steve N .
Hi Steve,

I guess so. For now, no spdif solution can go higher than 192KHz, so the maximal DoP would be DSD64 in this case.

But I confirmed piCorePlayer can go up to DSD128 over Pi GPIO.

Thanks for this clarification. This means that there is probably no point to doing a custom I2S to S/PDIF implementation to support DOP at 128. The off-the-shelf digital audio interfaces are sufficient.

Not sure I can use piCorePlayer. No mention of Roon in the documents.

piCorePlayer is different from Volumio and other player, basically it needs three things:

1. RPi with piCorePlayer SD;
2. A Logitech Media Server 7.9 (LMS), I would recommend to install it on a PC
3. Install a remote control squeezebox on you cell phone

I need Roon, so I think I will stick with Volumio.

Volumio doesn't support 384KHz/DSD128 so far. Hope they can upgrade soon.

According to Michelangelo, it does support up to 24/768 PCM. It's the drivers that do not support it.

got the isolator pi and the dsd decoder board for my raspberry pi 3 and my soekris dam1021 and it works now perfect with volumio but only dsd64 in soekris serial output its recognized as L02M when i try dsd128 or dsd256 volumio give me and [alsa]: Failed to configure DSD-over-PCM on ALSA device "hw:1,0". error hope they can fix that

but sound is spectacular

cheers janosch
