** Description changed:
- This bug is for tracking purpose.
+ The patches are in the linux-next already, it will be in the unstable
+ kernel automatically, and the patches will be in stable sooner or
+ later, so it will be in the Jammy kernel automatically in the future.
+
+ And our oem project requires the patches to be in the hwe-6.8 ASAP,
+ Here I submit the SRU to Noble and Oracular.
+
+ [Impact]
+ On a Dell machine, we plug a speaker or headset into the front audio
+ port, play sound to the speaker or headset, we get a 1/6 chance that
+ the speaker or headset couldn't output sound.
+
+
+ [Fix]
+ pick 2 commits from linux-next
+
+ [Test]
+ booting with the patched kernel,
+ 1. plug a speaker or headset in the front port
+ 2. play sound
+ 3. check if we can hear the sound or not
+ 4. repeat the step 1 ~ 3 20 times
+ 5. there is no failure
+
+ [Where problems could occur]
+ The patches change the depop and headset_type_detect routine, so it
+ is possible to introduce regression on pop noise and headset detection,
+ for realtek codec of alc285 and alc256 family, but the regression
+ possibility is very low, we tested the patches on a couple of Dell and
+ Lenovo machines, everything worked as well as before.
** Changed in: linux (Ubuntu Jammy)
Status: New => Won't Fix
