Raspberry Pi 5 Support

[zytegalaxy]

I tried installing the driver on a fresh bookworm image in Pi 5 and after reboot, the system does not boot anymore. On Pi 4, same OS image everything work well (v6.1).

I would like to get behind Pi 5 support and help to make it happen. This audio chip is super popular and it will be bummer not to have support for Pi 5...

The issue might be related to this:
raspberrypi/linux#5743

[flatsiedatsie]

I have it running on a Pi 5, on a bookworm LITE image I flashed today. I did have to add:

dtoverlay=i2s-mmap
dtparam=i2s=on
dtoverlay=seeed-2mic-voicecard

to /boot/firmware/config.txt

[makermelissa]

It installs and works fine on the lite version of bookworm using the above, but it kills the desktop even after uninstalling.

[zytegalaxy]

This script ended up working well for me:

https://github.com/ubopod/ubo-sdk/blob/main/system/setup/install_wm8960.sh

[makermelissa]

Thank you @ubopod. It appears to be working for me as well.

[HinTak]

Pi5 support and bookworm supports are separate issues. I believe the latter is fixed by #23 . Not sure about the former - anybody with a pi5 want to try after the #23 merge again?

[HinTak]

sorry, didn't mean to close.

[makermelissa]

Yes, #23 fixed an issue with Bookworm, but was it still not working not Pi 5.

[HinTak]

@makermelissa is the desktop issue same as lxpanel problem mentioned elsewhere?

I am a bit confused - @flatsiedatsie and @ubopod seems to have something that works?

[makermelissa]

I'm not sure what the lxpanel problem is. However, installing causes the desktop environment to stop working, but I can still SSH into the Pi and play audio just fine. The solution @ubopod mentioned works in the desktop environment, but isn't working for me on the lite version.

[HinTak]

@makermelissa pulseaudio seems to interfere with the desktop environment - #8 .

[makermelissa]

Thanks, I'll see if removing it first (or after) fixes the issue.

[makermelissa]

Uninstalling PulseAudio had no effect. Still no desktop.

[HinTak]

@makermelissa surely there are signs why it doesn't start - e.g. if you can still ssh in, as root, have a look at sys log - for systemd based systems, it is journalctl -r -b (since this boot), you might have to hunt around /var/log to see what other sys log mechanisms record.

[makermelissa]

I'll take a deeper look into the issue and let you know if I see something that stands out.

[makermelissa]

Here are the relevant sections of the log that stood out. Much of it is repeated:

[makermelissa]

Reinstalling lightdm lets it boot to the desktop once again, but it loses any customizations and looks like the default debian desktop rather than the Raspberry Pi bookworm desktop.

[HinTak]

The repeatedness is meaningful - lightdm refuses to start, so systemd try to start it over and over.

@makermelissa I think there is a apt.log (or as part of systemd messages) about installed packages. So it would be interesting to know what is most recently installed because of lightdm. It looks like it might depends on pulseaudio - that's a bit insane surely, the display manager needing to play sound?

[makermelissa]

Makes sense with what I was seeing. I'll keep looking, but probably a bit later today.

I haven't been able to get it working on my Pi5 with the Respeaker 4-Mic Array v1.2.

With a fresh copy of bookworm lite I can install without issue. But I don't see any devices listed.

The solution @ubopod mentioned works in the desktop environment, but isn't working for me on the lite version.

My observation on a lite installation of bookworm is that when I ran the script, rebooted the device and played some audio, I heard nothing, I had to set "Playback" and "Speaker" values to a non-zero value in alsamixer to hear things:

I'm not sure what the lxpanel problem is. However, installing causes the desktop environment to stop working, but I can still SSH into the Pi and play audio just fine. The solution @ubopod mentioned works in the desktop environment, but isn't working for me on the lite version.

I confirm the solution suggested in #19 (comment) works on lite version too

[AIWintermuteAI]

PR here
#29
See the below comments.

[HinTak]

@AIWintermuteAI I am not convinced about pull - for two reasons, it just loads the 2-mic device tree so doesn't apply to the other devices; the i2cdetect -y .... lines in seeed-voiceccard is supposed to auto-detect what device is actually connected, and load that automatically.

So the fact that force-loading the device tree works, seems to suggest that on p5, the i2cdetect -y ... code is broken. Can somebody with a p5 and some devices connected, runs the 3 i2cdetect -y lines and show the result? I mean just run these 3 lines:

i2cdetect -y  1 0x1a 0x1a
i2cdetect -y  1 0x35 0x35
i2cdetect -y  1 0x3b 0x3b

`

[HinTak]

It seems that i2cdetect on P5 is indeed faulty : raspberrypi/linux#6056

[HinTak]

@AIWintermuteAI this upstream issue seems highly relevant: raspberrypi/linux#5743 - have a read. It seems to suggest modifying the device tree overlays.

[HinTak]

This sort of explains why the 2-mic card is easier to get to work - it doesn't do playbacks.

[AIWintermuteAI]

@HinTak yes, after a look at the issue it seems that the PR I made is more a quick patch rather than actual long-term solution. I'll close it.
I've been away from all the reSpeaker stuff for quite a while now and it's not immediately clear to me what needs to be modified in the device tree overlays. I do have a Pi 5 here for testing tho.

[fonix232]

@HinTak looks like recent versions of the Pi5 kernel have fixed the I2C detection issue. I'm on 6.6.28+rpt-rpi-2712 and i2cdetect -y 1 properly shows the 4-mic HAT being installed:

admin@pi5:~ $ i2cdetect -y 1
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:                         -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- UU -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --

(note that at this point I had the drivers loaded hence the UU state)

The service also correctly identifies the 4-mic array and loads the appropriate config and state files. However, arecord -L still returns no devices:
