Hi, I opened an issue on pulseaudio repository at https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/1125 about the problem about the detection of jack output, and I have been forwarded there, that mailing list, at https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/1125#note_784…. The related outputs and logs are baked into the issue, and seems that the outputs tells that alsa driver did not reported jack as plugged after suspend. Thanks for understanding, Sincerely, validatedev

[PATCH] ALSA: intel8x0: Fix missing check in snd_intel8x0m_create
by Dinghao Liu 01 Feb '21

When device_type == DEVICE_ALI, we should also check the return value of pci_iomap() to avoid potential null pointer dereference.
