pulseaudio on Rpi4, bookworm, 64bit

[bjoernbusch]

Hello void,

I know that this is completely unmaintained, but maybe someone is still listening in on this and has some ideas. I really like the phat-beat hat and it's still working fine, but I wanted to upgrade the RaspberryPi underneath for different reasons. I started the old install scripts on a brand new bookworm 64bit.

• OS_NAME could not be determined, so it patched that variable
• The python package can't be installed via python anymore, but via apt, so I patched that
• wiringpi is now available from here: https://github.com/WiringPi/WiringPi/releases/download/3.1/wiringpi_3.1_arm64.deb, so I patched that
  • 3.2. didn't work, don't remember the exact log anymore, but it said to use 3.1 instead
• So the installation seems to run through.

The phatbeat Python library doesn't properly connect to the board, when doing phatbeat.set_all(0,128,0,0.1) it crashes due to

Traceback (most recent call last):
  File "/usr/bin/phatbeatd", line 192, in <module>
    phatbeat.set_all(0,128,0,0.1)
  File "/usr/lib/python3/dist-packages/phatbeat/__init__.py", line 250, in set_all
    setup()
  File "/usr/lib/python3/dist-packages/phatbeat/__init__.py", line 325, in setup
    GPIO.add_event_detect(button, GPIO.FALLING, callback=_handle_button, bouncetime=200)
RuntimeError: Failed to add edge detection
Exception ignored in atexit callback: <function _exit at 0x7faf6e5a80>

I can live without the actual phatbeat LED stuff, I only care about audio output, so I removed the GPIO.add_event_detect call from the python library.

Now my last hurdle seems to be that pulseaudio can't connect to the actual board.

I guess both the Python issue and the pulseaudio issue are due to some GPIO changes, but here I'm a little but clueless. Any further hints would be appreciated.

Maybe @Gadgetoid, I saw you commenting on these things in the past.

Audio

I'd guess the issue with audio playback is that all instructions/install scripts put stuff in /boot/config.txt which is now just a file that reads:

DO NOT EDIT THIS FILE

The file you are looking for has moved to /boot/firmware/config.txt

Which is rather unhelpful.

I'm reasonably sure you can just add dtoverlay=hifiberry-dac to /boot/firmware/config.txt and at least the audio side of pHAT BEAT will work fine.

LEDs

For user control of the LEDs you'll eventually be able to use pimoroni/apa102-python#9

That APA102 library (which is what the LEDs on pHAT BEAT are, fundamentally) needs some updates with all the stuff I've learned over the last few months before it's ready for prime time though.

Buttons

These are just regular GPIOs on the following pins:

BTN_FASTFWD = 5
BTN_REWIND = 13
BTN_PLAYPAUSE = 6
BTN_VOLUP = 16
BTN_VOLDN = 26
BTN_ONOFF = 12

They're active-low, with a pull-up so you can probably just try the following in /boot/firmware/config.txt to see if it works:

dtoverlay=gpio-key,gpio=5,keycode=163
dtoverlay=gpio-key,gpio=13,keycode=165
dtoverlay=gpio-key,gpio=6,keycode=119
dtoverlay=gpio-key,gpio=16,keycode=114
dtoverlay=gpio-key,gpio=26,keycode=115
dtoverlay=gpio-key,gpio=12,keycode=166

With the expectation that this will make those buttons behave like volume up/down, prev/next, play/pause and stop keyboard media keys. (I haven't tested this!)

The event codes header, that serves as a lookup table for the keycode, value is here: https://github.com/torvalds/linux/blob/e67572cd2204894179d89bd7b984072f19313b03/include/uapi/linux/input-event-codes.h#L189-L190

Adding dtoverlay=hifiberry-dac to /boot/firmware/config.txt get me passed the GPIO errors, but the errors about the profile persist and there is no sound yet. Any further ideas?

[Gadgetoid]

I can't believe I'm writing these words, but Unable to autolaunch a dbus-daemon without a $DISPLAY for X11 suggests audio wont work without booting up into Raspberry Pi Desktop...

Are you running the full desktop or Lite flavour of Pi OS?

What are you launching to try and get audio playing?

[bjoernbusch]

yeah, I guess I should have read all the way to the right :)

No, it's just the Lite version of Pi OS. I'm using it as a headless radio player. I've added some MQTT subscription in the phatbeatd code, so that I could remotely turn on the radio, that's why I don't need the buttons and the LEDs.

Let me try to through the desktop onto this machine then

[Gadgetoid]

Do you have any luck running something simple like: speaker-test -c2 -twav ?

[bjoernbusch]

hm, I guess a little bit of UI didn't help.
