the patch is in the linux-next, and just sent the patch to ubuntu 5.11
and 5.13 generic kernels.


** Description changed:

- No audio/mic from internal speakers/build in microphone running Ubuntu
- 20.04, 20.10 or 21.04  .  Can connect via USB headset and audio will
- work.   Tried suggestions from Dell XPS 17 (9700) but this is the new
- model and fixes do not work. Currently running 21.04 with proposed.
+ This patch is for soundwire audio, and only ubuntu 5.11-generic
+ and later kernels support soundwire audio driver, so this patch is not
+ sent to groovy and focal kernels.
+ 
+ For oem-5.10 and oem-5.13 kernels, since this bug is not from OEM
+ project, it is not urgent to merge this patch to OEM kenrels, after
+ the patch is in the hirsute and impish kernels, the oem kernels will
+ have this patch when syncing with generic kernels.
+ 
+ [Impact]
+ On the Dell XPS 17 (9710) machine, the audio card is not detected when
+ booting hirsute or impish kernels. So the audio doesn't work on this
+ machine with ubuntu linux 21.04 or 21.10.
+ 
+ [Fix]
+ Backport a upstream patch, this will set the correct codec config
+ for this machine: rt711 for headset, dual rt1308 for spks and rt715
+ for internal mic.
+ 
+ [Test]
+ Booting up with the patched kernel, the audio card is detected, test
+ internal speaker and internal mic, all work well, plug a headset,
+ the headphone and external mic work well too.
+ 
+ 
+ [Where problems could occur]
+ This change only applis to the Dell machines with the 
+ DMI_PRODUCT_SKU equals to "0A5D", if this could introduce the
+ regression, it will make the audio (speaker, internal mic and headset)
+ can't work anymore on the Dell machine with that PRODUCT_SKU, but this
+ possibility is very low, and we tested the patch on the machine, so
+ far no regression is found.
+ 
+ 
+ No audio/mic from internal speakers/build in microphone running Ubuntu 20.04, 
20.10 or 21.04  .  Can connect via USB headset and audio will work.   Tried 
suggestions from Dell XPS 17 (9700) but this is the new model and fixes do not 
work. Currently running 21.04 with proposed.
  
  Have tried hirsute-proposed (5.11.0-24-generic) with no luck.
