Allo Boss DAC intermittent problem

[hardcharger]

I've tried searching this forum, but haven't had any success finding a solution.  If this has already been answered, I'd appreciate if someone could point me to that post.

 

I'm having a problem with a Boss DAC on RPi3b+ running PiCorePlayer (originally v7 and now v8).  I have it all installed in the Allo aluminum case using a Nirvana SMPS.  When I first seat the DAC and power everything up, it is recognized just fine and SqueezeLite starts fine.  If the power is cut (unplugged) and then connected again, Squeezelite doesn't start.  I have to pull the whole thing apart again and reseat the DAC.

 

I have "Allo Boss DAC (and MiniBoss)" selected as the Audio Output in the SqueezeLite settings.  This configures the Output setting to "hw:CARD=BossDAC".  The ALSA Setting is "8,4,<blank>,1,<blank>".

 

When it boots and fails to find the Boss DAC, under Diagnostics I see this for SqueezeLite Output Devices:

 

Output devices:
  null                           - Discard all samples (playback) or generate zero samples (capture)
  default                       
  plugequal                     
  equal                         
 

I see these entries in dmesg:

 

[    9.980697] snd-allo-boss-dac soc:sound: snd_soc_register_card() failed: -517
[    9.984154] snd-allo-boss-dac soc:sound: snd_soc_register_card() failed: -517

[   10.033185] pcm512x: probe of 1-004d failed with error -121

 

I'm hoping someone here can point me in the right direction to get this sorted out.   Thanks in advance!

Hi,

I am having the same issue with my Allo Boss DAC v1.2 (without USB-C port), the same results in dmesg output. @Audio_Allo could you please share possible solution?

Thanks!
