Thank you for the answer but it remains confusing.
1 – On my PI 2 where is LMS I activate it ok but on my PI zero where are my DAC cards what do I do?
Because no LMS on it.
2- What is the option in the Shairport advanced settings where I can enter the IP? what effect does this produce?
3 – I see Shairtunes in the plugins under LMS but when I activate it does not matter but after restarting the option is unchecked.
I am really confused in all this I am in dire need of your help.
thank you in advance
