I performed a lot of tests and finally I am posting the results. Keep in mind that I am using Rpi\Rpi2\Rpi3 + Raspbian + pure MPD + USB DAC since years and I never experienced any problems, but I was looking to add a touch\LCD display, so i got the official Raspberry 7'' touch LCD and switched to Volumio, RuneAudio, pCP, etc.
With pure MPD, even with very high resolution up to 384 kHz \ 24 bit, the sound was always perfect, then I started to add the LCD \ Touch. Of course with pure MPD, even with the LCD, the sound was perfect, but not with pCP :-( Two main issues with pCP: 1) the WiFi is unstable and the performance poor with pCP 3.20. With the older 3.11 performances always poor, but at least was stable. Even if I avoid using channels 12 and higher, even if thw built in WiFi connects at 54 Mpbs, performances are very poor and at least 5 times worst than with Raspbian. I suppose it is a driver problem. Anyway, with the wired Ethernet, pCP sounds perfect. 2) After being sure pCP 3.20 was working very fine with the wired Ethernet, with a fresh SD card just imaged from scratch, I installed Jivelite. Now playing any high resolution audio will produce randomic noise (pops, glitches, and scratches) during the playback The higher the resolution, the more frequent the noise. Increasing the buffer improve very little the performances, but the problem is still present. Loading the FLAC \ PCM files from the local SD card or from a USB media makes NO differences versus lodading from the NAS Playing with the LCD \ touch during the playback, will produce immediately noise in the audio. For example, if I change the volume Anyway, leaving the LCD un-touched, noise is still present. Even controlling the player from the web browser. Any idea how to work out this problem? Any suggestion?
