I just assembled my Pi 3 Model B with the HiFiBerry Amp+. I used the Volumio image downloaded from volumio.org. I hooked up my Dayton Audio 6ohm bookshelf speakers and navigated to the IP address for volumio. The software looks fine - it found some music I put on a USB stick but when I play, it goes through the motions but I get no sound whatsoever. Any ideas what to look at first?
Ok, I just discovered the "Playback Options" and I have sound now, although I have to turn the volume up to about 23 before I can hear any sound at all.
I have the following settings configured. Are there any recommended settings that I should change to get optimum performance out of my hardware?
Output Device: Hifiberry DAC
I2S DAC: On
DAC Model: Hifiberry Amp
DSD Over PCM (DoP): On
Volume Normalization: Off
Audio Buffer: 8MB
Buffer Before Play: 20%
Mixer Control: Master
Default Statup Volume: Disabled
Max Volume Level: 100
Volume Curve Mode: Natural
I'm using more or less the same configuration as you. Same hardware, same software. I have severe problems which are probably caused by Volumio bugs.
50% of boots result in no WiFi connection despite strong WiFi signal, resulting in no connectivity
50% of boots result in Hifiberry AMP+ being totally silent despite Volumio looking good.
So my configuration works randomly about 25% of the bootups...! Is this something you have experienced too?
Are you running the 0.979 build of Volumio? I have a wired network connection and haven't even tried the WiFi. It is working pretty well for me. Yesterday I installed the Spotify plugin and it is working pretty well and I ran it all day yesterday. There was one time where playback stopped, but I just hit pause and play and it started back up - I chalk that up to an issue with the connection to the Spotify server. The only real issue I have at this time is that I cannot get it to mount my NAS folder with all my music on it. It works fine when I copy the files to the USB, however. I haven't really taken the time to try to resolve the NAS issue yet, but hopefully I can work that out. The only time I've had the Amp be silent is when I hadn't yet configured the playback settings to use the Amp. It also reset those settings to default after I installed the Spotify plugin, other than that mine has been working pretty well. The main difference between us is that I am not using WiFi.
