Description Ben Cotton 2021-02-02 15:50:12 UTC
This is a tracking bug for Change: SOF as default audio driver for Intel LPE hardware
For more details, see: https://fedoraproject.org/wiki/Changes/SofDefaultForIntelLpe

Intel LPE audio hardware has 2 drivers in the mainline kernel the SST driver and the SOF driver, switch the default driver from SST to SOF.

Comment 1 Ben Cotton 2021-02-10 22:55:20 UTC
We have reached the 'Code Complete (testable)' milestone in the Fedora 34 release cycle. If your Change is in a testable state, please set the status to MODIFIED. If this Change will not be ready for Fedora 34, please set the version to rawhide.

The 100% code complete deadline is Tue 2021-02-23.

Comment 2 Hans de Goede 2021-02-11 11:11:09 UTC
This has been testable since the 5.11-rc1 kernel build by adding snd_intel_dspcfg.dsp_driver=3 to the kernel commandline; and I have been going over the extensive test plan from the Change page this way for a while now (working my way through all the different hw configurations).

And now that this merge-req has landed:
https://gitlab.com/cki-project/kernel-ark/-/merge_requests/889

The SOF driver is now the default on Bay and Cherry-Trail hardware, starting with the 5.11.0-0.rc7.20210210gite0756cfc7d7c build, moving this to modified.

Comment 3 Ben Cotton 2021-02-16 15:52:05 UTC
Reminder: The change complete (100% complete) deadline for Fedora 34 changes is Tuesday 23 February. At that point, changes should be 100% code complete, along with supporting documentation where appropriate. Please indicate this by setting the tracker bug for your change to ON_QA.

Comment 4 Hans de Goede 2021-02-16 16:24:47 UTC
The kernel changes for this have landed in the F34 repos with the 5.11.0-0.rc7.20210210gite0756cfc7d7c.150 kernel build, moving to ON_QA.

Comment 5 Ben Cotton 2021-03-19 21:12:14 UTC
Deferring to F35 per Hans
