Additional context

No response

[pelwell]

Is the 6.1.64 kernel also mainline?

And what's the most recent kernel you can remember with working sound? You may find something in the system logs (perhaps from journalctl).

[tartanpion]

Working sound with all the kernels before. Last good kernels : linux-rpi4 6.1.63-1 or linux-rpi4-mainline 6.6.2-1. Mainline is just the name for manjaro to differentiate 6.1/6.6.

[pelwell]

Thanks - that helps a lot.

At least this looks like it is getting blamed on an ARCH-ARM packaging issue here:

https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/3411

Tag me here if I need to compile a test kernel for the OP.

[pelwell]

Interesting, but it's the later error messages that looked more relevant:

From a quick test this commit https://github.com/raspberrypi/linux/commit/1985fab7f8520e4629c09eba8d40ebf57a862851 which landed in 6.6.3 and 6.1.64 seems to be triggering that - I also noticed that on LibreELEC with kernel 6.6.3 on RPi5 and 6.1.64 on RPi4

[   13.206401] pcm512x 1-004c: Failed to sync cache: -22
[   13.211506] pcm512x 1-004c: ASoC: error at snd_soc_pcm_component_pm_runtime_get on pcm512x.1-004c: -22

EDIT: using an iqaudio DAC here (guess pretty much all pcm512x cards should be affected)

[pelwell]

Thanks, @HiassofT. Can you confirm that reverting that commit fixes the problem?

[HiassofT]

yes, with the commit reverted pcm512x is back to normal

LibreELEC:~ # dmesg | grep pcm512x
[   11.153738] pcm512x 1-004c: No SCLK, using BCLK: -2

and I have working audio (RPi5, LibreELEC master, kernel 6.6.3)

[pelwell]

That's great - it's reverted on rpi-6.1.y. and on its way to the others.

[tartanpion]

I have working audio too after the revert.

[pelwell]

Cool. That reversion will remain in our kernel builds until the problem is fixed upstream.

You can close the issue if you feel the matter has been dealt with.

[HiassofT]

@pelwell I've reported the issue upstream https://lore.kernel.org/stable/ZWo45hiK-n8W_yWJ@camel3.lan/

[pelwell]

Thanks - I think your proposed patch will be the accepted fix.

[HiassofT]

I've submitted the fix, hope it dribbles down to stable soon https://lore.kernel.org/lkml/20231203222216.96547-1-hias@horus.com/T/#u

[HiassofT]

@pelwell @popcornmix quick heads up: the upstream fix will be in the next stable kernels, Greg just added it to his queues

[HiassofT]

The fix is now upstream in 6.1.68/6.6.7 kernels.

@popcornmix could you please update rpi 6.1 and 6.6 branches?

[pelwell]

That's done now - thanks for the diagnosis, and for getting a fix upstreamed so rapidly.

[pelwell]

Oh dear - re-reading your message I should just have waited for the next merge.
