Hi,
I have bought RPi3 some time ago, installed OSMC on it and used for music only - with no problem. Now I bought DAC+ Pro and when I attach it it simply doesn't boot - it hangs on splash screen. When I detach it, it works again. I have applied that Bluetooth fix but it didn't change anything.
What am I doing wrong? Should I reinstall OSMC with DAC+ Pro attached during installation?
Hi,
if you see a rainbow screen, you should disable the EEPROM:

I've tried it - no change, it still hangs.
It is not hanging on rainbow screen but on blue screen with OSMC logo. I can see on top of the screen that something is going on in the background. There are communicates like:
(1 of 3) A start job is running for set time using http query
(2 of 3) A start job is running for permit user sessions
(3 of 3) A start job is running for LSB: RPC portmapper
and it goes round with the three lines above.
Ok, in this case I guess, you have LIRC enabled on the same GPIO that the DAC+ is using. You should completely disable this before adding the DAC+.
If this still doesn't work, you need to contact the OSMC developers how to debug it.
Best regards,
Daniel
Could you please tell me how to turn of LIRC, or enable it on different GPIO (if possible)?
I found it, it could be turned off in options - now the system started and I can say it's working.
Unfortunately I hear hum (buzz, noise, I don't know how to call it) in headphones when no music is playing. :-( It was like that with Raspberry only, I thought if I buy this HiFiBerry it will solve the issue. Is it like that it won't work correctly at all, or I'm still doing something wrong?
Hi,
what is connected to your Raspberry Pi. How do you connect your headphones?
Best regards,

I have a keyboard attached to Rpi, Rpi is attached to the TV using HDMI cable. I use 2RCA-MiniJack cable (4m long) to connect it to line in input of my computer, and I'm listening sing headphones plugged in to the same computer.
The above setup is only for testing purposes, in the end it will be connected to amplifier.
In this case I would suppose a ground loop between TV, Raspberry Pi and computer. Also a 4m RCA cable isn't optimal. Try to keep this short.
I would start taking away the HDMI cable and check if this changes something. Next step would be replacing the computer by an amplifier.
Best regards,
Daniel
Again you're right Daniel - when I remove HDMI cable the noise disappears! So, the question now is how to deal with such ground loop? I had the same noise when I connected monitor, RPi and amplifier. Should I use some special kind of cables, or plug all the stuff into the same outlet? How to approach this problem?
