It is not easy to debug without hardware, so the best way is to report

Trying more things here. I changed Hdmi.conf back to my original file.
The system boots with your v5 kernel.

Still no sound. Seeing Dummy Output.

Thanks for this. I tried it with your Hdmi.conf from v4. I could boot up
to the login screen. After seeing the login GUI screen for a few
seconds, the system just freezes (no longer responds to mouse and
keyboard input). Attaching dmesg.0. I guess there is some file system
check or something else
The last resort:
I built a kernel from the Intel audio driver tree, please test it
https://people.canonical.com/~hwang4/25skipi915/v5/, please keep using
the Hdmi.conf from v4.
If that doesn't work, please file a bug against Intel sof kernel:
https://github.com/thesofproject/linux/issues/new,
Now I tried your Hdmi.conf. Again, seeing black screen for a couple of
reboots. Kept trying -26 v4 kernel. Then maybe the 3rd or 4th time, it
booted. Here are more info for this case.

Forgot to say that I see "Dummy output" in pavucontrol, and there is no
sound.

Hi Hui Wang. I'm on a -28 kernel. Did what you said to install the -26
v4 kernel. As usual, comment out "options snd-intel-dspcfg
dsp_driver=1". Use my Hdmi.conf. When I rebooted with the -26 v4 kernel,
I got stuck at a black screen again. But this time, I decided to try it
a couple of times. It
please install a higher version kernel like 5.4.0-28/29 first, boot with
the new kernel, then sudo dpkg -r --force-all linux-image-
unsigned-5.4.0-26-generic, install the v4 testing kernel to do the test.
I installed the v4 testing kernel on my machine, there is no errors:
Sorry. How should I start installing the v4 kernel? I just downloaded
and did "sudo dpkg -i *.deb". But I got "errors encountered installing..
(the kernel)".
Do I have to do " sudo dpkg -r --force-all (something here)" first? Also
what will happen to the original -26 kernel?

This is the testing kernel based on the -26 kernel:
https://people.canonical.com/~hwang4/25skipi915/v4/
And don't forget the Hdmi.conf if kernel has no obvious errors or failures on
audio.

I don't know that.
Maybe there is some necessary fixup in the -26 kernel but not in the
-25 kernel. After the -27 is ready, I will build a testing kernel based
on -26 kernel, then you could test -26 testing kernel, if it has boot
issues, you could choose the -27 kernel to boot then.

okay. I just restored to my original Hdmi.conf. "options snd-intel-
dspcfg dsp_driver=1" in alsa-base.conf still commented out.
Now the -25 kernel v3 does not boot anymore. I am confused now. I could
boot in #15. It is supposed to be the same setting. I got stuck at a
black screen. But if I
[ 14.652221] sof-audio-pci :00:1f.3: error: no reply expected, received 0x0
This message is common on all machine with sof driver, so we could ignore it.
According to dmesg in the #15, the kernel driver already worked. you
could run "aplay -l" to check (sorry, not alsa -l).
So after update
* Tried your Hdmi.conf. It turns out that the system did not even boot.
It did not bring me to the usual Ubuntu login GUI screen. I got stuck at
a black screen with the message

Before I try your Hdmi.conf, I am attaching my one

) in case it is relevant.

I guess v3 kernel will work successfully, after boot up, you could run

the -25 kernel was successfully installed, but according to log, there
is some driver issues not fixed, so please try this v2 kernel:

download the v2 kernel:
• Installed kernel 5.4.0-25-generic that you provided. The command dpkg -i gave
an error about missing headers.
• Comment out dsp_driver=1. Restart.
• Despite some error about missing headers, Grub menu shows a new entry for
kernel 5.4.0-25. I selected it.

** Description changed:
On Ubuntu 20.04, by default, sof-audio-pci is used. I only have "Dummy

"snd-hda-intel" is loaded instead of sof-audio-pci.
Okay. I will use "dsp_driver=1" for now then. Just for your information,
before I installed Ubuntu 20.04, I used 18.04. On 18.04, I tried a few
kernels on https://kernel.ubuntu.com/~kernel-ppa/mainline/ ranging from
5.3.x, 5.4.x, 5.5.x, 5.6.6 (I can't remember which x I tried anymore). I

OK, there is at least one problem in the driver I know, and will build a
testing kernel, maybe next Monday.
Please use the workaround "dsp_driver=1" temporarily.
