Small update for my previous post :
1- it's possible to 'lock' the audio output interface by saving the MPD Conf (not only select another interface) , it's kept after reboot (at least with my hifiberry dac) but the MPD Conf of Rune page don't show the correct choice (UI issue only I think).
2- On CPU load with software volume control and 192-24 files, it's around 17-18 % with leval at 100 and it jump to 20-21% when level it not at 100. This is a very small increase and thus demonstrate than the resampling process it very efficient (New MPD one I guess). I can hear those who will say it's not anymore bit perfect but the CPU load seems to prove that that it's bit perfect when playing a 100 andnot below (which is quite logical). If i'm correct, software controled level is just great cause it convenient and same time bit perfect when playing a 100...
3- Seems it's very very long to change to disabled control level, UI spinning for some minutes .... so there is probably something wrong, but it's possible just be patient !
With volume control disabled, the CPU load is around 17-18 % with the same file (192-24) wich seems confirm that software control is really bitperfect at level 100
Guys, I have a small suggestion. I use two RPI, one with the hifiberry dac in office and another with USB connection to a TEAC UD-501 for my main system. I changeg the hostname of one through the UI and its just working fine !
My suggestion is to make the host name visible somewhere in the UI since the URL is not visible any more when using a chrome application link
My best suggestion would be to use the title tag for that, so that would be visible (and not intrusive) in the window title bar.
