While rebuilding my whole system, xfce-extra/xfce4-alsa-plugin-0.2.1 failed to compile.

This seems to be fixed in version 0.3.
See :
https://github.com/equeim/xfce4-alsa-plugin/issues/5
https://github.com/equeim/xfce4-alsa-plugin/commit/0779be7a4eb22d520a9da3709c951e548a60fb60

Maybe a patch can be adapted for 0.2.1 ? If not, maybe stabilize 0.3 instead. Let me know.
Thanks.

Same bug here, i had to downgrade dev-lang/vala to 0.36.20 to be able to download xfce-extra/xfce4-alsa-plugin

[Comment 4 David Duchesne 2020-09-11 19:59:14 UTC]

closing as xfce-extra/xfce4-alsa-plugin-0.2.1 is not in portage anymore (replaced by xfce-extra/xfce4-alsa-plugin-0.3.0, which fixes the issue)
