Bug Description

I have the following in `.config/pulse/default.pa`:

```
.include /etc/pulse/default.pa
load-module module-echo-cancel aec_method=webrtc aec_args="analog_gain_control=0 digital_gain_control=1"
```

After a reboot, there is no echo cancelled device.

And then I run `systemctl --user restart pulseaudio` and the echo cancelled devices appear.

That's a bit of a hassle.

I noticed that if I comment out the loading of the `module-card-restore` in `/etc/pulse/default.pa` then this problem does not occur. The echo cancelled devices are present on the first run. Of course, I do like having my cards restored!

Hello, I got similar issue, I am using this in default.pa

### Enable echo/noise cancellation
load-module module-echo-cancel aec_method=webrtc aec_args="analog_gain_control=0 digital_gain_control=1" source_name=echocancelledsource
set-default-source echocancelledsource

It works when I use pulseaudio -k in terminal, echo cancelled sink/sources are shown and the echo cancelled source is default. This also retains on log off and re login but after a restart it does not apply at all.

For now my solution is to add a entry to gnome startup application preferences as "pulseaudio echo cancel" and use this in command "pulseaudio -k".

I tried using "sleep 5/10/30 && pulseaudio -k" as command but no matter what sleep seconds it didn't load module at all, only using the command without sleep works.

This method also retains volume/state of echo cancelled sources so it's fine for now hope it gets fixed soon officially.
