Description of Issue
-
Issues, using 3 SOtM sMS NEO endpoints during the last two weeks
- Qobuz Studio streaming service
- Starts, drops, skips tracks, and stops eventually for all bitrates, especially Hi-Res and MQA.
- Issues occurs on all SOtM endpoints regardless of DAC used
- Prior to June 2021, there were no issues streaming Hi-Res files
- The issues started after upgrading the SOtM devices (3) firmware and kernel. Upgrades were recommended by SOtM after adding the SMSL M400 DAC
- Currently, there are no apparent issues streaming local (LAN-local area network) content 44.1kHz 16bit WAV files at a 1411kbps bitrate
- SOtM suggested adjusting the roon configuration for buffer and sync, but none of that helped.
- Sometimes an SOtM device will disappear from roon/Settings/Audio, requiring a cold boot of the SOtM. Yes, the DAC is attached and online.
- Qobuz Studio streaming service
-
No issues with the following, but used for reference in the same LAN
4 Sonos Connects (ZP120) (an incredible 17 years old)- Roon finds all 4 Sonos Connects in a spit second and plays both external and LAN content without any issues or interruptions 24x7
- Although roon server down converts all external qobuz content greater than 44.1 kHz 16 bit, there are no issues playing
- No issues streaming local (LAN-local area network) content WAV at 1411kbps 44.1kHz 16bit
- I cannot compliment the 17 year old Sonos endpoints more. They simply work without issues and are a benchmark for connectivity and sync. Unfortunately, they do not provide streaming beyond 44.1kHz 16bit. Sonos is missing a large market segment.
I contacted qobuz ((case number: 17448)) and SOtM (no case number).
I searched through the issues in the roon community, but did not find any with three (3) SOtM endpoints streaming qobuz HI-Res.
Thx
