Just thought it worth mentioning, this new patch that fixes sound again, seems to have ressurected an old issue with PLL unlock. I'm seeing journal entries after fresh boot ......

It's a very old issue, maybe you'd know more about it.
I noticed this error on my Orco device used for tests many moons ago, but I could never find out what led to this error case, it wasn't deterministic and didn't impact the audio quality. All I could do is rate_limit it... If we have an A vs. B situation it'd be really helpful to diagnose further.
Is there really a causality between the changes from Hans and this PLL unlock error? Are you 100% sure this was not present in the previous install you used (4.18.14 as mentioned earlier in the thread)?
Thanks

Well, numerous boots, kernels, headphone inserting - no PLL or 'Daleks'. My laptop must have been haunted that day (halloween). I'll put it to bed.
So you can no longer reproduce. Bummer. Note this might be caused by the temperature of the laptop when you were running the tests...
Anyways if you hit this again and you can reproduce it, please give adding a msleep(10) after code mucking with the clk a try.

Right then, I can make it unlock and 'daleks' by going into pavucontrol and switching the Profile back and forth from Stereo Output to Stereo Output+Analog Mono Input, which is actually something I've done to make it correct itself as well. I don't use the mic or anything so I've had it set to Stereo Ouput only which I 'think' has somehow made it more stable for me. With all my playing around, one of the things I did was clean out my .config/pulse folder which meant by default the 'Profile' in pavucontrol was set to Output+Input, which seems to help trigger the PLL issue when inserting headphones.
So what would you like me to do, as I can trigger it on demand it seems.
Please give the attached patch a try (on top of my patch for the clk quirk) and let us know if that fixes these errors.
Regards,
Hans
Ok Hans, I tried your patch on top of the quirk, and sound is immediately garbled (daleks again), and switching pulseuadio profiles or inserting headphones doesn't make it correct itself, whereas before sound would be fine, UNTIL, I did something like insert earphone etc.
