Strange behaviour: out of nothing my R-Pi 3 won’t recognise my Schiit Modi mkI DAC anymore… I recently updated to Volumio 2.413 and that worked fine for several weeks so I don’t expect any issues there.
It started last week, when I had to reset the internet and wifi. Volumio automatically reconnected to wifi, but when I accessed it, it had lost connection to the DAC (“Failed to open alsa device”). Several reboots with plugging and unplugging the DAC later, still no luck, until I did a Factory Reset on the system. There it was again.
Few days later I shut down the Pi (as precaution before I reset the router), and again when I started the Pi the DAC was gone. Since then, I cannot get the DAC to be recognised. I did a Factory Reset again, and when that didn’t work a full fresh install of Volumio.
The DAC has power, but is not recognised whatsoever in Volumio, on none of the USB ports. The output of “lsusb”:
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6d:0002 Linux Foundation 2.0 root hub
On my Windows laptop the DAC is recognised straight away. Interestingly I’ve had a similar issue with my Zero W, which was unresolved until I finally decided for a Pi3 with stronger power supply.
Any idea what is going on? The DAC should be one of the easiest, since it’s driverless and has worked already since Raspify…
Thanks in advance for the help!
