I have some issues with USB audio output using Volumio. A short summary:
- I have installed Volumio and tried 3.5 jack analog audio output from Pi (ALSA selected as output)
- I have connected DAC based on CM6631A USB received, restarted Volumio and I can only see “ALSA” and “Nothing selected” in audio output menu
- When I click “reboot” it restarts and I can see “Audio output” now and music comes out from connected USB DAC
- When I power Pi off and power it on again I have the same issue as before - no sounds from USB DAC and I can only see “ALSA” and “Nothing selected”
Any idea what can be wrong and why I can’t see “Audio output” (USB) in menu after power on? (with USB DAC connected)
Is there any difference between power off / power and “reboot” sequence? As I mentioned before, when I click “reboot” in system menu the “Audio output” option is visible and it works while if I power it on I can’t see it and no sound from USB DAC.
