HATs and other add-ons • Re: Raspberry Pi DAC + does not work with Rasbperry Pi 5

Are you actually using Raspberrry Pi OS Bookworm, as the cat /proc/version says ubuntu?
My Pi5 Bookworm has:

Code:

cat /proc/versionLinux version 6.6.31+rpt-rpi-2712 (serge@raspberrypi.com) (gcc-12 (Debian 12.2.0-14) 12.2.0, GNU ld (GNU Binutils for Debian) 2.40) #1 SMP PREEMPT Debian 1:6.6.31-1+rpt1 (2024-05-

OP's output:I ran into this a few years ago with something completely unrelated: the stuff in brackets in the /proc/version output is details of the system the kernel was built in, NOT the running system. So it looks like 'dom' built that particular kernel on an Ubuntu box. Or perhaps it was built automagically by a Github-hosted runner? That kernel is also not part of Raspberry Pi OS (at least not yet) - you must have used something like rpi-update, which is generally not recommended, to get it.

As to the OPs original question: I'm using the old IQaudIO version of this HAT on a Raspberry Pi 5 with no issues. With the Raspberry Pi version there should be no need to change anything in config.txt, although if the HAT happened to leave the factory with a blank EEPROM then simply adding 'dtoverlay=rpi-dacplus' (i.e. not the IQaudIO version) should get it working.

What else is plugged into your Pi 5? In particular, is anything else attached to the 40-pin GPIO header, or the top of the DAC?

Can you post a copy of the output of the 'dmesg' command? and 'aplay -l' (that's a lowercase L)?

I suspect some kind of hardware failure in the HAT.
