Just got an Airlens to replace my matrix SPDIF II. My Airlens is connected via I2S to Direcstream MKI - BHK Preamp- McIntosh amp. I have a NUK (with all my music).. All running thru ROON. I have updated both the firmwares. I can play music dsd256, from ROOn ,into airlens and into my Directstream, and it will show dsd64. My device setup for airlens in ROON is: MQA capabilities: No MQA support; Vol Control: fixed; Max sample rate:up to 384kHz; Max bits: 32; Max sample rate (DSD); up to DSD256. Clock master: default; Enable MQA core decoder: No; My device setup for Directstream in ROON is: MQA capabilities: No MQA support; Vol control: Device Vol; Max sample rate (PCM): up to 192kHz; Max bits per sample (PCM): 24; . Clock master: Default; Enable MQA: No; Im using in ROON my direcstream as the player. Any help will be greatly appreciated. Thanks, ---

Send a screenshot of your Signal Path when playing DSD256. It might provide an answer. I likely can’t provide it but someone else might! Good luck Dave ---

Roon appears to be doing this, not AirLens found this from 2019 (about 5 years before AirLens release)…[Please explain sigma-delta modulator in my signal path - Roon Software Discussion - Roon Labs Community](https://community.roonlabs.com/t/please-explain-sigma-delta-modulator-in-my-signal-path/79277) ---

Underneath Airlens what do pins 3 and 4 look like - both should be ON for DSD 256, you might need to check pin 5 for native vs DOP also Does your MK1 have the Bridge card installed and if so is it still connected somehow? Try removing and re-adding any and all audio zones in Roon. ---

All the pins are up on the Airlens. I have not removed the bridge card on the MKI yet, to try .
