I noticed a problem a over the summer after upgrading from Debian 9 stable to Debian 10 testing: PulseAudio no longer recognized my Intel HDA audio devices. At the time I was able to switch to my monitor's audio connected via nVidia HDMI so I sidestepped the problem hoping that a future update would fix it. They haven't. Fast forward a few months and I've rearranged my workspace and now need to get the Intel HDA working again.
Here's what I've looked at so far...

When I go to Sound Settings, all I'm seeing is the Dummy Output device. (The nVidia devices are no longer listed here because in rearranging things, I'm using a different monitor without audio so there's no HDMI audio device connected currently.)
I've tried to clearing out the PulseAudio configuration thinking I might have some legacy cruft around via:

I have another partition on this machine which is still running Debian 9 stable, where the Intel HDA works under PulseAudio, and there do appear to be differences in the ALSA drivers vs. Debian 10 so below are the differences I noticed...

Debian 10 Buster is still in testing. The most you can do here is file a bug report and wait until it's officially released and has actual support.

But a bug report for what? (i.e. the kernel drivers? ALSA? PulseAudio?) It's clear that the behavior has changed but it's not at all clear to me what the source of the problem is. I also don't know if the issue is specific to my current configuration or if a complete reinstall (not something I can do right now) would reproduce. Debian package maintainers want a specific package that is at fault with steps to reproduce... I don't believe I'm there yet.

You'll need to troubleshoot PulseAudio and see if there's a problem with the kernel or something else. You could also just wait until it's officially released and see if the problem is resolved.

@blihp did you solve your issue? I'm experiencing the exact same one…

I noticed a problem a over the summer after upgrading from Debian 9 stable to Debian 10 testing: PulseAudio no longer recognized my Intel HDA audio devices. At the time I was able to switch to my monitor's audio connected via nVidia HDMI so I sidestepped the problem hoping that a future update would fix it. They haven't. Fast forward a few months and I've rearranged my workspace and now need to get the Intel HDA working again.
Here's what I've looked at so far...
Debian 10 Testing
The kernel sees it:

However PulseAudio doesn't see the device at all:

When I go to Sound Settings, all I'm seeing is the Dummy Output device. (The nVidia devices are no longer listed here because in rearranging things, I'm using a different monitor without audio so there's no HDMI audio device connected currently.)
I've tried to clearing out the PulseAudio configuration thinking I might have some legacy cruft around via:
rm ~/.pulse/* ~/.config/pulse/*
Debian 9 Stable
I have another partition on this machine which is still running Debian 9 stable, where the Intel HDA works under PulseAudio, and there do appear to be differences in the ALSA drivers vs. Debian 10 so below are the differences I noticed...

Debian 10 Buster is still in testing. The most you can do here is file a bug report and wait until it's officially released and has actual support.

But a bug report for what? (i.e. the kernel drivers? ALSA? PulseAudio?) It's clear that the behavior has changed but it's not at all clear to me what the source of the problem is. I also don't know if the issue is specific to my current configuration or if a complete reinstall (not something I can do right now) would reproduce. Debian package maintainers want a specific package that is at fault with steps to reproduce... I don't believe I'm there yet.

You'll need to troubleshoot PulseAudio and see if there's a problem with the kernel or something else. You could also just wait until it's officially released and see if the problem is resolved.

Debian 10 Buster is still in testing. The most you can do here is file a bug report and wait until it's officially released and has actual support.

But a bug report for what? (i.e. the kernel drivers? ALSA? PulseAudio?) It's clear that the behavior has changed but it's not at all clear to me what the source of the problem is. I also don't know if the issue is specific to my current configuration or if a complete reinstall (not something I can do right now) would reproduce. Debian package maintainers want a specific package that is at fault with steps to reproduce... I don't believe I'm there yet.

You'll need to troubleshoot PulseAudio and see if there's a problem with the kernel or something else. You could also just wait until it's officially released and see if the problem is resolved.

Should anyone else run into this, here's a workaround to force PulseAudio to use the ALSA device...
First, confirm you know the correct sound card and device you want by playing some audio directly via ALSA:
aplay -D plughw:<CARD#>,<DEVICE#> /usr/share/sounds/alsa/Front_Center.wav
In my case I wanted the optical audio output so based on my aplay -l output as seen in my question above it was:
aplay -D plughw:0,1 /usr/share/sounds/alsa/Front_Center.wav
Make a note of the card and device number and add an entry to /etc/pulse/default.pa (replace 0,1 with what worked for you in the previous step):
load-module module-alsa-sink device=plughw:0,1
I added this line immediately before the .ifexists module-udev-detect.so line in the file (i.e. underneath the ### Load audio drivers statically comment)
Then run the following as the user your desktop session is logged in as (i.e. not as root):
pulseaudio --kill
pulseaudio --start
Then you should be able to open Sound Settings to see and select the card:
At this point, you should have audio playback through PulseAudio working again. (Something I noticed is that pacmd list-cards will still not list the card even though it now works) Reminder: this is a workaround and not the long term fix so be sure to make a note to yourself to undo this at some point in the future to see if it's been fixed properly. But it gets audio working for the time being.

I ended up here because of the very same problem, after upgrading from Stretch, the audio disappeared. Similar symptoms and outputs (Nvidia card and Intel HDA sound). While following instructions, though, I've found that I couldn't get this step to work:
root@desk:~# aplay -D plughw:0,0 /usr/share/sounds/alsa/Front_Center.wav
aplay: main:828: audio open error: Device or resource busy
I found that the culprit was timidity:
root@desk:~# fuser -v /dev/snd/*
USER PID ACCESS COMMAND
/dev/snd/pcmC0D0p: timidity 1274 F...m timidity
/dev/snd/seq: timidity 1274 F.... timidity
Once I killed it, I could proceed editing /etc/pulse/default.pa and everything snapped into place. I'm still not sure if the issue was the missing PA sink or timidity taking over.
I've also considered filing a bug report, but I'm not sure where would be more appropriate. If you have any suggestions, I'll be happy to follow your lead and add my support to the report.
Thank you for sharing the solution!

root@desk:~# aplay -D plughw:0,0 /usr/share/sounds/alsa/Front_Center.wav

I found that the culprit was timidity:

I've also considered filing a bug report, but I'm not sure where would be more appropriate. If you have any suggestions, I'll be happy to follow your lead and add my support to the report.

Debian 10 Buster is still in testing. The most you can do here is file a bug report and wait until it's officially released and has actual support.

But a bug report for what? (i.e. the kernel drivers? ALSA? PulseAudio?) It's clear that the behavior has changed but it's not at all clear to me what the source of the problem is. I also don't know if the issue is specific to my current configuration or if a complete reinstall (not something I can do right now) would reproduce. Debian package maintainers want a specific package that is at fault with steps to reproduce... I don't believe I'm there yet.
