Review on 🎧 NanoSound ONE Case by Argon - High-Fidelity Raspberry Pi Audio Player with HiFi DAC (Digital to Analog Converter), Argon ONE Case for Raspberry Pi 4 (Rpi4 Not Included) by Dakota Afzalian

Thought it was an Argon 40 product but it is. The DAC is a product developed and maintained by Nanomesher, a subsidiary of Volumio. The support site states that this DAC is compatible with other operating systems, but there is no information on how to do this. I asked questions in nanomesher forum but after 4 days there is no answer. In order for the DAC to work with Raspberry OS, I just needed to know which driver to put in /boot/config.txt. But Nanomesher never provided this simple driver information. If you need a dedicated headless audio DAC from Volumio, this might be for you. But I needed the full functionality of the Raspberry OS for video playback, web surfing etc. via HDMI as well as multi-room streaming. By the way, after installing Volumio, you need to download and run the Nanomesher software installer using Linux commands. This used up all the space on the 32GB SD card. IOW, no room for add-ons like Pandora etc. IOW, you need to buy 64GB memory cards for all features to work. FYI, although there is an M.2 version, Volumio doesn't boot from an SSD, so a uSD is still required and the SSD can only be used as media storage. I now have 2 excellent Argon One M.2 cases (purchased direct from Argon40.com) that boot directly from the SSD (RPi 4 USB boot), no USD. I love these cases but dismiss Nanomesher's apparent loyalty to Volumio instead of supporting customer needs. It just goes to show that after-sales customer care is crucial to gaining satisfied customers. /boot/config.txt. By building this into the Raspberry OS I now have the full OS functionality I want. ;-)
