DSD Playback Being Converted to PCM with Volumio Motivo

[Alan_Cheung]

@vadim

Thank you for the detailed information regarding your setup. I’ve reviewed the diagnostic data enabled on your account and the Volumio Motivo device capabilities. Here’s what’s happening:

1. DSD-to-PCM Conversion in Roon

• The Motivo endpoint advertises "dsd_mode":"none" in its RAAT output configuration.
• This indicates that, as far as Roon is concerned, the device does not currently accept native DSD or DoP streams over RAAT.
• As a result, even if the hardware supports native DSD, Roon will automatically convert DSD64 tracks to PCM before sending them.

2. Why this occurs despite hardware support

• RAAT (Roon Advanced Audio Transport) relies on the endpoint reporting its supported formats and DSD handling.
• Since the Motivo endpoint reports "dsd_mode":"none", Roon assumes it cannot handle DSD natively.
• Without explicit DoP or native DSD support advertised in the RAAT client, Roon defaults to PCM conversion.

Right now, Roon is converting DSD64 to PCM because the Motivo RAAT client does not report DSD capability ("dsd_mode":"none"). Enabling DoP or native DSD in the Motivo (if available) is required for Roon to send DSD without conversion. We also contacted the partners team to clarify the information about supported formats, and we will update you here as soon as possible.

When will Roon and Volumio provide a precise update to the Motivo endpoint encoding or capabilities reporting, so that the device can advertise its full native DSD or DoP support to Roon?
A clear timeline or commitment from both teams would be very helpful, as resolving this limitation is extremely important for my listening setup.

I would appreciate a direct answer regarding the timeframe or release plan for this feature update, so users like myself can finally enjoy native DSD playback as promised by the hardware capabilities.

Additionally, I have previously raised a question regarding KKBOX playback compatibility (discussion link: Regarding Album Playback Issues with Roon and KKBOX [Ticket in]. Could you please provide an update on the progress towards resolving that issue as well? Both matters are important for my user experience, and I hope to hear concrete feedback and next steps on both fronts.
