Please bear with me, newbie here.
Just set up Runeaudio on a raspberry pi 3B with a hifiberry DAC+ card installed. Set it up according to instructions, got wifi working, can log in via my browser. Edited the config.txt file to use the hifiberry. I can get into the MPD settings, and select the hifiberry dac+ option, save settings, and can start playing a track off a usb drive. However, the browser interface then immediately locks up, becomes unresponsive. The player keeps playing, but won't stop or anything. I have to unplug the device and reboot it to log back in. When I do, it has reset to the default internal dac setting.
This is as far as I've gotten with this - and it's very frustrating. None of this is covered in the troubleshooting. I'm probably not providing nearly enough details - I'm using a mac, up to date everything. Please let me know what I need to tell you to help you help me - thanks!
