RPi3B+ and Allo Boss 1.2 = no WiFi
#1
Am I really the only person with this issue? 

I'm running Moode 4.3 on a Raspberry Pi 3B+ with an Allo Boss DAC 1.2. 
I can't use the Pi headless like that because neither my smartphone nor my tablet detect the Moode AP unless I disconnect the Boss DAC HAT. 

I got a replacement Boss DAC 1.2 thinking the first one may have been defective, since my Pi3B+ had a really hard time initializing it (it often failed to show two lit green LEDs and I got the 'Failed to find ALSA device' error). The replacement initialized, displayed two green LEDs and plays sound just fine, but the Moode AP still will not operate with the Boss DAC 1.2 connected. 

I got a 5VDC 4A power supply. I never see the Pi's power LED go dark anymore, but that still did not get the Moode AP working. 

I have an older (original) version Boss DAC, and the Moode AP works with that older version Boss DAC installed on the Pi3B+. 

I subsequently purchased a Topping D10 USB DAC, removed the Boss DAC 1.2 and installed the Topping DAC instead. Now the Moode AP is visible to my phone and Moode works headless. 

That tells me the problem is with the Boss DAC 1.2 (later version) in this setup. 

Is there anyone else who has encountered this problem? 
Is anyone out there successfully using Moode + Allo Boss DAC 1.2 headless?

Hello RonGon,

You are not the only one.

I did not realize it, but after I have installed the allo boss dac recently, my AP no longer works. (which I don't need in my set-up)

Thanks Herman. Good to know.

I bought a Topping D10 USB DAC to use with the Pi for headless operation. Eventually I'll add a USB wifi adapter to the Pi and try again with the Boss DAC.

It may turn out to be a blessing in disguise. For me the advantage of an onboard WiFi transceiver has to be balanced against the problems of possible RF interference with a DAC hat, of encasing the RPi (metal cases effectively block the signal) and of poor antenna placement in a cabinet full of cables. You may find a USB WiFi adapter on the end of a short USB cable an improvement.

And, wow, I did not know of the Topping D10 until you mentioned it. The specs are impressive and the price looks unbeatable. I love the case and retro display. I wish they made a matching blank case I could use with it.

Regards,
Kent

I have an Allo Boss 1.2 fitted to my Pi in the Allo Boss aluminum case and not seen those issues. This Pi's normally connected to Powerline Ethernet but it's had no problem with Wi-Fi when I've tried it other than my WiFi signal being weak in that room, hence the Ethernet.

Coincidentally I'm currently waiting for my Topping D50s to arrive so looking forward to that.

After using two ALLO BOSS v1.2 HAT DACs with the same RPi unit the suspicion would normally fall upon the Allo BOSS v1.2 HAT DAC v1.2 for acting like a Faraday cage of sorts BUT @vinnn' s previous post appear to negate this conclusion (albeit without any detail on what RPi model and MoOde version)...

Still... have you tried:
- running the RPI+HAT DAC combo out of ANY enclosure
- a newer, say, the latest MoOde version (v 4.4 is based on an old Raspbian version)
- (ultimately) an addon USB WiFi device

I would understand if you'd rather not carry on further testing as you are now happily using an USB DAC.
