FYI: I am new to RPi and have put together a RPi 3 with DAC+ Pro (with HiFiBerry plastic case) with Volumio 1.55 (from HiFiberry Installer) only. Pretty much a plain vanilla set up for DAC+ Pro connected to my NAS. In general, it works as expected but I run into the following issues with respect to the on-board WiFi:
Issue #1: I couldn’t get the on-board WiFi to connect (similar to someone above). Rebooted, tried different wifi network on different routers, etc., nothing seemed to work and kept getting the “No Wireless Interface Present” status. So, I’ve continued to use the Ethernet, but would like to get WiFi to work without a dongle.
Issue #2: After about 3 failed attempts of setting WiFi (in #1), Volumio starts acting weird … volume pointed to zero but the actual output is 100% and volume dial became non-responsive and not adjustable. I wiped the SD and reload Volumio to start over. Every time I tried to set up WiFi for about 3 times, the same volume issue came out again, and sometimes playlist would even become non-responsive. And I had to reload the SD image again.
Any insights would be appreciated.
