Fix for sof-firmware on HP EliteBook 850 G6 HDMI audio no longer work

I have upgraded my Linux by
Everything went smoothly.

[mila@mila-hpelitebook850g6 etc]$ cat lsb-release
[mila@mila-hpelitebook850g6 etc]$ uname -a
Linux mila-hpelitebook850g6 5.16.13-desktop-1omv4003 #1 SMP PREEMPT Wed Mar 9 19:33:24 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

But the problem was with HDMI audio.
I have tried both pipewire-pulse and pulseaudio-server.

When I tried pulseaudio-server I did not see any HOMI profile to choose.

When I tried pipewire-pulse I did not see any HOMI profile to choose but I could choose Pro Audio with 3 -5.
I could switch to Pro Audio 3 and I saw that it works but without any sound.

The main problem was with my old setting from OpenMandriva Lx 4.2
I have install sof driver there. During that time it was a good solution,
See my post OMA 4.2 Sound and microphone on HP EliteBook 850 G6.
But the time has changed.

How have I solved it?

I have upgraded into sof 1.8.
It did not help me.
I found a solution on these sites.
I have run echo "options snd-intel-dspcfg dsp_driver=1" > /etc/modprobe.d/alsa.conf
Now I use the kernel driver and there are many HDMI profiles to choose.
See for possible numbers.

Thank You for your post and solution.
I have HP Elitebook X360 1040 G5, Ubuntu 22.10 Kinetic with 5.19.0 kernel.
And I had this problem. No HDMI Audio output available (where there was TV connected).
echo “options snd-intel-dspcfg dsp_driver=1” > /etc/modprobe.d/alsa.conf
(and restart) solved problem. Thank You! :-).
This comment is for other peaple with such issue, for easier solution find.
