Could you please send the error, we will check and let you know what is missing.
Just a guess here without seeing the error. Is this perhaps because the SOF F/W binary that was loaded was not signed with signature trusted by the platform and the platform required validation?
SOF on AMD was first introduced for Chromebooks which don't use the same authority for firmware binary verification that general purpose UEFI notebooks would use.
So I compiled the latest sof firmware from main branch commit 90c14e56cb, and now it seems I get additional errors that I didn't get a few months ago when I last tried: [ 38.251393] snd_sof_amd_renoir 0000:03:00.5: enabling device (0000 -> 0002) [ 38.252944] snd_sof_amd_renoir 0000:03:00.5: unknown sof_ext_man header type 3 size 0x30 [ 38.252955] snd_sof_amd_renoir 0000:03:00.5: Firmware info: version 2:0:0-90c14 [ 38.252957] snd_sof_amd_renoir 0000:03:00.5: Firmware: ABI 3:26:0 Kernel ABI 3:23:0 [ 41.345068] snd_sof_amd_renoir 0000:03:00.5: ------------[ DSP dump start ]------------ [ 41.345080] snd_sof_amd_renoir 0000:03:00.5: Firmware boot failure due to timeout [ 41.345085] snd_sof_amd_renoir 0000:03:00.5: fw_state: SOF_FW_BOOT_IN_PROGRESS (2) [ 41.345137] snd_sof_amd_renoir 0000:03:00.5: invalid header size 0x7f841000.

The kernel I'm running on is based on the asoc tree from Mark Brown: git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git

Merge remote-tracking branch 'asoc/for-6.3' into asoc-nextLet me know what other information you need in order to debug this.
As per the error in https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/soun...,
the firmware header was not proper.
Even the header parsing is done correctly, you will run into other issues related to signed firmware validation error as mentioned by mario.limonciello@amd.com .
So please Use x86 based implementation without DSP that is recommended 2.
