I have a microRendu (1.3 board) running Version 2.7 that has suddenly refused to ID any USB DAC connected to it. It ran flawlessly before it stopped working (outputting to a Musical Paradise MP-D2 DAC (XMOS). I went through the recommended boot up sequence numerous times, tried different USB cables, , different network cables, 4 different DACs and still nothing. The power supply is a HD Plex. The unit is found on the network. The DAC Diagnostics in every trial I have done shows: No audio devices found. Attach a USB DAC to this system. And the System settings shows: Audio device list Error in alsa-capabilities (v0.9.1): aplay did not find any soundcard I do not have a custom DAC setup and the output is set to USB. I have reinserted the SD card and updated and rebooted a few times. This is the boot up process I used as posted by Jesus: Do the following in order: Power down the DAC and the microRendu Power up the DAC Power up the microRendu It worked perfectly fine before so I have no idea what is going on now. What kind of other troubleshooting steps can I do to confirm the USB output is dead? I see scant information on the web regarding a bad USB output on the microRendu but it seems that may have happened to my unit. Any suggestions?
