[alsa-devel] azx_probe() called twice
Dear Linux folks,
With the attached debug patch, `azx_probe()` seems to have been called twice on the ASRock E350M1. Is that expected? It also differs, that it’s only called once during some boots, and twice during others.

How many HD-audio devices does it have?

I’d say one (ALC892), but how do I verify that? Please find lspci and Linux logs attached from an older boot with Linux 4.11.
Kind regards,

I meant HD-audio controllers.

So you have two HD-audio controllers (one for HDMI/DP and another for Realtek codec). It's expected behavior that azx_probe() gets called twice.

True. Too many log files I looked at lately, and I got confused. Sorry for the noise.
Could the probe theoretically be done in parallel?
Kind regards,

I guess you can pass snd_hda_intel.async_probe boot option.
