Hi,
I have indications of a possible bug in the MPD output selector.
I am trying to guide a friend of mine to install and use e3 on a RP4.
For him, it is not possible to select an USB DAC with the name "iFi (by AMR) HD USB Audio".
The menu selection does not "stick", a page reload makes the 3.5mm plug or HDMI come back.
And thus it is not possible to turn off on-board devices.
His e3 is updated to 20200412, SD expanded to 8GB.
I am told that in the previous version of RuneAudio (e1?) there was no problem for him using this DAC.
It reminds me of a case a few years back when I ran into a problem with AirPlay, I named the RP Airplay name to a string "RuneAudio(AirPlay)" and It was not working. If I removed the parenthesis from the name it was ok. This was reported and corrected.
Could it be that there is a similar problem in handling USB device names that contains "()"?
I am running a RP4 with e3 myself with a DAC named "Cambridge Audio USB Audio 2.0" and I have no problem.
Unfortunately we do not live close by so I cannot test his device with my DAC.
I would be very happy if you could comment on this.
