Comment:
`CONFIG_SND_HDA_INTEL_HDMI_SILENT_STREAM` just sets the default for a module parameter:
```
$ modinfo -p snd-hda-codec-hdmi | grep silent
enable_silent_stream:Enable Silent Stream for HDMI devices (bool)
```
To enable the parameter, run the following and reboot:
```
$ echo 'options snd-hda-codec-hdmi enable_silent_stream=1' | sudo tee /etc/modprobe.d/snd-hda-codec-hdmi.conf
```
Instead of rebooting, you can also try reloading any `snd-hda*` modules, but YMMV with that.

In any case, once the `snd-hda-codec-hdmi` module is `modprobe`d again, the parameter should be enabled:
```
$ cat /sys/module/snd_hda_codec_hdmi/parameters/enable_silent_stream
Y
```
The parameter is even runtime-switchable, although YMMV with that too:
```
$ echo 1 | sudo tee /sys/module/snd_hda_codec_hdmi/parameters/enable_silent_stream
1
```
You guessed it, `echo 0` to switch it off again.
