Mobile Stax Amp SRM-D10 connected through USB-C

Description Of Issue


I recently started listening to Roon on my MacBook using my mobile Stax SRM-D10 amp connected through USB-C. The problem is, unlike my Naim NDX 2, Roon always “forgets” about that device after a restart. Roon only lets e select my MacBook speakers and my NDX 2 but not my D10.

I need to re-enable the device including labeling and applying my preferred DSP settings which is partcularly annoying.

Why is that happening and is there a way to save my audio device setup?


Hello @GalaxyGlider, and thanks for your report! Are you seeing this consistently after a reboot? Also, has this always happened with this device? Have you tried it with another remote?

Hi @nuwriy,

thanks for your reply. This happens after every reboot. Roon recognizes the device in my Audio setup but I have to enable and label it before it can be used as an audio zone. DSP settings also reset and need to be re-enabled for that device.

On my iPhone or iPad I can see the device but also would have to enable it before I can use it as an audio zone. To further explain the SRM-D10: It is a mobile amplifier that can connect to a computer or mobile device using USB. In USB-mode (it can also do line-in) it is recognised as an audio device by my Mac and also as a new audio device by Roon but always as a new device.
