Created attachment 299987 [details] Alsa info output captured after resume of device where issue is seen Steps to reproduce the issue: 1. Connect the 3.5mm headset that has inbuilt mic. 2. Suspend the system. 3. Now plug out the 3.5mm headset and wake up the system. Expected output: Once the system resumes from suspend, both headset & headset mic detection shouldn't be seen as it is plugged out during suspend. Observed output: After system resumed, headset is still shown as detected but not headset MIC. Tried the below upstream for-next kernel but still the issue is observed. Tip tried: commit 8e7daf318d97f25e18b2fc7eb5909e34cd903575 (takashi/for-next) Author: Bixuan Cui <cuibixuan@linux.alibaba.com> Date: Wed Dec 1 16:58:54 2021 +0800 ALSA: oss: fix compile error when OSS_DEBUG is enabled But after reverting https://lore.kernel.org/alsa-devel/20210310112809.9215-3-tiwai@suse.de/ from the patch series, the issue is not seen. Attached the alsa-info.sh output(alsa-info) captured when the issue was seen.
Could you give the alsa-info.sh output from the latest Linus tree? Also, you're overriding the setup somehow via model option and patch option. Please drop those. And, if it's a proto-type machine, you'll likely have to write your own fixup. This codec might need to call alc_combo_jack_hp_jd_restart(codec) at resume, usually done via a fixup call with HDA_FIXUP_ACT_INIT. (Or by luck, some existing fixup may work.)

Hi Takashi, I have tried with Linus master (commit# below) and still see the issue. Attached above the alsa info captured when issue happened. Merge: 93db8300f6870 0c3e247460558 Author: Linus Torvalds <torvalds@linux-foundation.org> Date: Thu Dec 16 15:02:14 2021 -0800 Merge tag 'net-5.16-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net Also, I have checked with the team both model and patch options are needed for headset jack detection.
Created attachment 300099 [details] Alsa info captured with revert of patch with Linus master where issue is not seen
Hi Takashi, I have also attached the alsa-info captured with the revert of https://lore.kernel.org/alsa-devel/20210310112809.9215-3-tiwai@suse.de/. I see the mixer controls diff and also the headset node Node 0x21 [Pin Complex] wcaps 0x40058d: Stereo Amp-Out Control: name="Headphone Playback Switch", index=0, device=0. After adding couple of prints: + /* ignore unsol events during system suspend/resume */ + if (codec->core.dev.power.power_state.event != PM_EVENT_ON) + return; + I see control is getting back from above during such unsol events and it is not reported & not handled and hence we are hitting the issue. However, it seems the below lines are needed to be executed to handle such unsol events during suspend. if (codec->patch_ops.unsol_event) codec->patch_ops.unsol_event(codec, ev);
Hi Takashi, Any inputs from the above observation. Thanks.
Hi Takashi, Do you need any additional data for the issue?
Hi Takashi, We still see this symptom on v5.10 kernel. Do you have any suggestion for this?
It's not the right place to resolve this problem. If you look to hda_call_codec_resume() function, there is the jack state handling - snd_hda_jack_set_dirty_all() and snd_hda_jack_report_sync() / or jackpoll_work activation. Try to figure the better solution for this hardware when the codec is resumed. Alternatively, you can set the jackpoll_ms kernel module option (see modinfo snd_hda_intel).
Right, you need to verify whether the pin detection (AC_VERB_GET_PIN_SENSE) continues to work after the resume or not. As Jaroslav mentioned in comment 9, the basic flow is like: System resume -> hda_codec_pm_resume() -> hda_codec_runtime_resume() (with dev->power.power_state = PMSG_RESUME) -> hda_call_codec_resume() Then in hda_call_codec_reusme(), it calls snd_hda_jack_set_dirty_all() to mark all registered pins as dirty to re-detect the pin states. At the end of the function, it calls snd_hda_jack_report_sync() that updates the all pin states that have been still marked as dirty, and report the current jack states. If the jack isn't updated, something is broken in the code flow above.

Hi Takashi, Apart from the logs shared above, we added prints to track the pin detection AC_VERB_GET_PIN_SENSE and get_jack_plug_state(jack->pin_sense) in snd_hda_jack_report_sync after resume in the normal scenario (suspend resume with 3.5mm jack plugged in) and the issue scenario(3.5mm jack unplugged during suspend).

Hi Takashi & Jaroslav, Can we interpret driver behavior based on above info during the failure case?
The change in comment 14 does report only when get_jack_plug_state() returns true, i.e. only when the *already existing* jack state contains the bit. So, it makes little sense to track that point at all; it just reflects the known result. Instead, you should track jack_detect_update() call and what value is read at each invocation. I guess the hardware doesn't detect the jack properly by some reason during the resume there.
Hi, The issue got addressed in the latest TOT kernel. Hence, closing this bug. Thanks for all your support.
