Is there any way to "lock" Runeaudio to USB output? Or remove the possibility of MPD selecting the Pi's Analog or HDMI outputs?
I use my Runeaudio quite seldom, but have the problem that every once in a while my external DAC (over USB) disappears from the output interface list. Sometimes I can go into MPD and re-select it, but sometimes it is no longer there and I have to reboot to get it back. I haven't figured out why this is happening.
I have set a cronjob to reboot nightly, and it would be nice to prevent the RPi Analog or HDMI output to be selected during reboot if the DAC is turned off, which it will be during night.
