Hi,
yesterday i was testing with Linux 5.13-rc3 on my Raspberry Pi 4 B (multi_v7_defconfig) and i'm getting the following errors during boot:
[ 25.947494] vc4_hdmi fef00700.hdmi: ASoC: error at snd_soc_dai_startup on fef00700.hdmi: -19 [ 25.947512] MAI: soc_pcm_open() failed (-19) [ 25.947883] vc4_hdmi fef00700.hdmi: ASoC: error at snd_soc_dai_startup on fef00700.hdmi: -19 [ 25.947891] MAI: soc_pcm_open() failed (-19) [ 25.948566] vc4_hdmi fef00700.hdmi: ASoC: error at snd_soc_dai_startup on fef00700.hdmi: -19 [ 25.948577] MAI: soc_pcm_open() failed (-19) [ 26.500049] vc4_hdmi fef00700.hdmi: ASoC: error at snd_soc_dai_startup on fef00700.hdmi: -19 [ 26.500065] MAI: soc_pcm_open() failed (-19) [ 26.500608] vc4_hdmi fef00700.hdmi: ASoC: error at snd_soc_dai_startup on fef00700.hdmi: -19 [ 26.500617] MAI: soc_pcm_open() failed (-19) [ 26.502339] vc4_hdmi fef00700.hdmi: ASoC: error at snd_soc_dai_startup on fef00700.hdmi: -19 [ 26.502353] MAI: soc_pcm_open() failed (-19) [ 26.502569] vc4_hdmi fef00700.hdmi: ASoC: error at snd_soc_dai_startup on fef00700.hdmi: -19 [ 26.502578] MAI: soc_pcm_open() failed (-19)
Rootfs: Raspberry Pi OS 32 bit (April 2021)
But according to aplay -l both hdmi devices have been registered. Does anyone have seen this, too?
Best regards Stefan

I would assume it's due to this: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/driv...
It pre-dates my time working on the vc4 driver so I'm not really sure what this is supposed to prevent, but my guess is that it's there to avoid someone using the audio card before we have a display detected and connected, and its capabilities known (the first and more obvious one being does it support audio in the first place).
It's nothing new though, maybe it's the error printing itself that is?

It looks like there's no discussion on that link, is it the link you wanted to paste?

It looks like Mark wasn't particularly on-board with that change though :/
I'm not really sure what to do with it, really. The only issue I'm seeing is that there's some logging that doesn't look too nice. Is there anything else?
