Is there a way to at least silence these messages?
I'm looking at void snd_hdac_bus_update_rirb(struct hdac_bus *bus) and it looks like there's no way to silence it. It would be great if you made it possible to silence it or to limit it to a single message, e.g. snd_hda_intel 0000:07:00.1: spurious response 0x233:0x0, last cmd=0x1f0500 snd_hda_intel 0000:07:00.1: further spurious response messages will not be omitted
A similar bug was filed more than a year ago, see bug 202423. Not a single reply from ALSA developers. Is there any information I can provide so that you fixed it? It's really annoying.
Then there's bug 208487 which mentions a similar device: NVIDIA Corporation TU106 High Definition Audio Controller (rev a1)

A much older gpu is also affected - Geforce 680M.
A possible workaround is mentioned here: https://bugzilla.kernel.org/show_bug.cgi?id=204199#c14 however I'm not concerned with the switch to polling mode, I'm annoyed by a large number of never-ending error messages.

OK, the patch works for me, great. No more dmesg spam. I could have made it a snd_hda_module option but I see no reason to see thousands of these messages in the first place.
It's a HDMI device in Nvidia GPU, and it means that the GPU doens't respond to the audio verbs, so basically a bug in the graphics side. Are you using Nvidia graphics driver? If it were nouveau, it should have been done better in the audio component and the power management is linked tightly.

Somehow it's only happening after resume and it doesn't affect audio output at all, so the hundreds of error messages serve no purpose. > > Are you using Nvidia graphics driver?

Yes, I am, in fact I indicated it right away, comment #0 07:00.1 Audio device: NVIDIA Corporation TU116 High Definition Audio Controller (rev a1) Since NVIDIA doesn't want to address the bug (it's been known for a year and a half now) it would be great if kernel maintainers could at least somewhat alleviate it.
Basically it's a problem in the resume procedure where Nvidia graphics doesn't resume quickly enough before the audio gets resumed -- that's the wild guess, but who knows. It's Nvidia binary-only stuff. You might try to change codec->relaxed_resume = 0; in generic_hdmi_free() in patch_hdmi.c to codec->relaxed_resume = 1; This would suppress the forced resume when the device has been already runtime-suspended beforehand.

It's Nvidia binary-only stuff. I'm not sure about that - these messages keep on coming _infinitely_ after resume. It surely looks like it's because PulseAudio is poking and probing the card regularly. For instance, I've noticed that unlocking the PC generates a storm of these messages. Again it would be nice to silence them because I doubt a single user in the world can use them and they are mostly meant for kernel audio developers and one error message would be enough to realize that something doesn't work correctly. TLDR It would be nice if these messages were silenced unless kernel/ALSA debugging is turned on. > > You might try to change > codec->relaxed_resume = 0; > in generic_hdmi_free() in patch_hdmi.c to > codec->relaxed_resume = 1; > > This would suppress the forced resume when the device has been already > runtime-suspended beforehand. I'm not sure that'll help - see above.
Well, look at the messages you posted initially: [ 9426.756113] snd_hda_intel 0000:07:00.1: azx_get_response timeout, switching to polling mode: last cmd=0x001f000a This starts showing the spurious response. This already indicates something broken. And later on, it reaches to the state: [ 9427.760124] snd_hda_intel 0000:07:00.1: azx_get_response timeout, switching to single_cmd mode: last cmd=0x005f0900 and this means that the communication with the codec is completely broken, hence it switched to the emergency mode. After this point, the codec shouldn't return anything via the interrupt, but it still keeps doing that, and this unexpected behavior appears as the flood of response error messages. That is, the very cause is the communication error at the resume, and then the chip continues behaving weirdly after that, even if the HD-audio controller tries to communicate in the single command mode. And *why* it happens: no one knows, it's Nvidia voodoo box, hence nothing but guesses. So I asked you to try that. You can guess, but that's all about guess. For suppressing the spurious error messages after the single cmd mode switch, the change below might help. But this doesn't solve the primary problem at all, of course. --- a/sound/pci/hda/hda_controller.c +++ b/sound/pci/hda/hda_controller.c @@ -1122,7 +1122,7 @@ irqreturn_t azx_interrupt(int irq, void *dev_id) */ azx_writeb(chip, RIRBSTS, RIRB_INT_MASK); active = true; - if (status & RIRB_INT_RESPONSE) { + if (!chip->single_cmd && (status & RIRB_INT_RESPONSE)) { if (chip->driver_caps & AZX_DCAPS_CTX_WORKAROUND) udelay(80); snd_hdac_bus_update_rirb(bus);
Ho ho ho -- Merry Christmas I too am seeing these messages when various terminal sessons start to go into "lock-down". The resulting malfunction is to lock-out TERM sessions under my X-Windows session. Strangely, using CTRL/ALT/F1 (console) and resuming vis CTRL/ALT/F7on an Ubuntu system give me some "better" performance on the terminal ... On the coonsole and checked htop, etc, and every thing looks "OK" apart from teh dmes output showing likes like... snd_hda_intel 0000:07:00.1: spurious response 0x233:0x0, last cmd=0x1f0500
... What I'd like is to find a way to identify these HEX values. For instance, what is/are ... 1. cmd=0x1f0500 2. snd_intel => 0000:07:00.1 * I presume this is a message kind??? 3. response; "0000:07:00.1" * What is that string? What service(s) usees that IPv6 address? * Ought the miscreant responsible for publishing such "stories" as-if they were .. could be... fact-s / plausibilities 4.

It is still happening with 5.10.12. However, according to NVIDIA, they are working on a fix (as of 2021-02-08): https://forums.developer.nvidia.com/t/nvidia-hdmi-audio-errors-after-resume-snd-hda-intel-spurious-response-last-cmd/149003/12
This issue goes back to 2009. End User setup issues are the hardest to fix. resolution requires reading. * When you run lspci and then a different backended hardware identification utility, are there differing naming anomolies.??? What is the exact hardware spec'd? as per Manufacturer whitepaper.? # After every install, kernel,firmware,hardware, driver change or just because ..biannually; * I run update-pciids with the latest pci.ids.(and the rest) So the hardware is identified correctly. * # I then check off the "indentified" HW against the HW actual. # Is the correct hardware audio codec pinned on the mainboard and or in the bios?

NVIDIA has solved the issue themselves in the latest drivers but it may still affect older drivers which haven't been updated to include the fix. Can anyone running older NVIDIA drivers and a sufficiently recent kernel, 5.14.14, confirm that this is still an issue?
NVIDIA has fixed this in their driver.
