Hello,
I just received my Allo boss dac. I am trying to get the dac working but I can't retrieve it in my system settings as an output device.
I am using kodi 17.1 on a raspberry pi (latest version of hardware).
I added the "allo-boss-dac-pcm512x-audio.dtbo" in the overlays folder. Then I changed the config.txt to:
################################################################################
# License keys to enable GPU hardware decoding for various codecs
# to obtain keys visit the shop at http://www.raspberrypi.com
################################################################################
# decode_MPG2=0x00000000
# decode_WVC1=0x00000000
# decode_DTS=0x00000000
# decode_DDP=0x00000000
dtoverlay=pi3-disable-bt
dtparam=i2c=on
dtoverlay=allo-boss-dac-pcm512x-audio
################################################################################
# End of default configuration
# all values below this line were inserted from config.txt.bk (your old config)
# and can be merged with the above values
################################################################################
Can someone help me out? What am I doing wrong. The green power led on the boss board is burning.
Thx

Hi ,
Add below lines on top of dtoverlay=allo-boss-dac-pcm512x-audio line
dtparam=i2c_arm=on
dtparam=audio=on
gpu_mem=128
And then reboot and check the status.
And if not working pleas check boss driver is loaded or not using below command
aplay -l
It will display like allo boss dac
Please share the dmesg output and ls mod ouput also

Thank you for your support. I however must admit that I am a linux noob. I made the changes you suggested. Now alsa is displayed as an option. I can however only select ALSA: Default(bcm2835). Then music output is through HDMI.
A log file is made to http://sprunge.us/CADf

Hi, I have been trying to use Allo Boss with Kodi, followed the process as described above,
And updated the necessary lines in config.txt, still there is no sign of the BOSS DAC in AUDIO devices.
Attaching the screen shots of Openelec-Kodi. Also After giving the aplay command the Boss driver is showing as Device 1, and Device 0 is showing as ALSA BCM 2835.
Pls check the command file screen shot.
Waiting for further suggestion...

Hi, Thanks for the reply,
Already done that what you have mentioned in the above reply,
>>Boss hardware is on power, both the leds glowing green on boss.
>> Already added the 3 lines above dtoverlay=allo.... and system was rebooted.
>> Boss driver showing after giving the "aplay" command.
Card 0 showing ALSA BCM 2835
Card 1 showing Boss DAC
I think we need to set the Boss DAC as card 0,
Or disable the integrated audio...pls suggest.
I had attached 2 screenshots but they have not uploaded to previous comment,
Trying again..
