Pisound for Raspberry Pi 5?

Giedrius · November 24, 2023, 1:22pm

Finally we received our Pi 5 shipment.

There’s an issue in the kernel that prevents Pisound from working right away on Pi 5, but we’ll work with RPi Foundation to sort the situation out. Sometimes new releases are just shaky at the beginning, no worries.

Pisound on Pi 5

### Describe the bug Pisound is the I²S master, the default eeprom dt overlay w…e shipped it with is not working on Pi 5. I've noticed issue #5724, and based on it I found that doing this procedure manages to load the driver and register the card successfully, the card then is usable: 1. Add `dtoverlay=pisound,master` in `/boot/config.txt`. 2. Power up Pi 5 without Pisound attached, to skip loading its hat eeprom. 3. Run `sudo modprobe -r snd_soc_pisound` to unload the Pisound's driver (as it obviously failed to load without Pisound attached). 4. Carefully attach Pisound on powered on Pi 5. 5. Run `sudo modprobe snd_soc_pisound` to load the Pisound's driver, it loads ok this time. 6. Check `amidi -l`, `aplay -l`, `arecord -l` - it's listed as expected. Quick tests indicate that Pisound is fully operational once the driver manages to register the card. Powering on the Pi 5 without Pisound attached, but with the dtoverlay line in config.txt, is necessary, otherwise the system does not boot at all when the hat eeprom is available, and the dtoverlay line for the same hat is there. What should be done to make Pisound working on Pi 5 right out of the box? ### Steps to reproduce the behaviour Have Pisound attached as normal, the driver fails to register the card: ``` [ 3.200062] pisound: Detected Pisound card: [ 3.200072] pisound: Serial: PS-3...
