I still fighting with Pi5 Volumio issues. On Raspberry forum, Software Engineer at Raspberry Pi Ltd. said that on official system can be some problems with display because of drivers and still are added. Maybe here too, but Linux, Debian and other systems are outside my percepion.
Yes, it’s reason why I use older HV Pi4. Last HV1.5 dasn’t works with HifiBerry DIGI and few more.
I bought Pi5 because I use very good USB/Spdif module( I2S in Pi is software not hardware like my XMOS and CPLD / FPGA. Sound quality is on higher level) and I thought that if I haven’t problems with DIGI hat I can use Pi5… and now it is wrong decision - HDMI issue.
Good thing is, that I have few offer to sell it 2 x expensive than I bought it (it is because if you order it now, you must wait 3 months). I give Pi5 chance to start LCD. I will wait. I think that it is “Childhood disease”
