Hello Sasa,

Could you provide us with the topology and firmware binary present on
your machine?

Audio topology is located at /lib/firmware and named:

9d71-GOOGLE-EVEMAX-0-tplg.bin
-or-
dfw_sst.bin

Firmware on the other hand is found in /lib/firmware/intel/.
'dsp_fw_kbl.bin' will lie there, it shall be a symlink pointing to an
actual AudioDSP firmware binary.

Maybe this is the problem.

I think most of us are pulling the topology and firmware from the
chromeos recovery images for lack of any other known source, and it
looks a little different than this. Those can be downloaded like so:
https://gist.github.com/jmontleon/8899cb83138f2653f520fbbcc5b830a0

After placing the topology file you'll see these errors and audio will
not work until they're also copied in place.
snd_soc_skl 0000:00:1f.3: Direct firmware load for
dsp_lib_dsm_core_spt_release.bin failed with error -2
snd_soc_skl 0000:00:1f.3: Direct firmware load for
intel/dsp_fw_C75061F3-F2B2-4DCC-8F9F-82ABB4131E66.bin failed with
error -2

Once those were in place, up to 6.0.18 audio worked.

Is there a better source for the topology file?

The reasoning for these asks is fact that problem stopped reproducing on
our end once we started playing with kernel versions (moved away from
status quo with Fedora). Neither on Lukasz EVE nor on my SKL RVP.
However, we might be using newer configuration files when compared to
equivalent of yours.

Recent v6.2-rc5 broonie/sound/for-next - no repro
Our internal tree based on Mark's for-next - no repro
6.1.7 stable [1] - no repro

Of course we will continue with our attempts. Will notify about the
progress.

Kind regards,

Hi Jason,

as I understand you've tried to do bisect, can you instead try building kernels checking out following tags: v6.1 v6.1.1 v6.1.2 v6.1.3 v6.1.4 v6.1.5 v6.1.6 v6.1.7 v6.1.8 and report when it stops working, so it narrows scope of what we look at? I assume that kernel builds are done using upstream stable kernel (from https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/).

Thanks,
Amadeusz
