Pulseaudio and sound.extraConfig step on each other

[dfoxfranke]

Setting hardware.pulseaudio.enable to true while setting sound.extraConfig to any non-empty value will cause a build failure because alsa.nix and pulseaudio.nix both attempt to create /etc/asound.conf. The correct result would be for the contents of sound.extraConfig to be written out at the end of /etc/asound.conf, after the stanzas provided by pulseaudio.

Somewhat relatedly, the ! in pcm.!default and ctl.!default in pulseaudio's generated config doesn't make a whole lot of sense. ! means "override", currently there is nothing for it to override, and we would like user config to override generated config, not the other way around. However, as long as user config is placed in the file after generated config then I don't think the ! actually makes any difference.

I am having this issue as well. Easily replicated by setting those two options.

Should be fixed with #27000. If there still is a problem, please reopen this issue.
