Created attachment 396138 [details] build.log Google says av_resample_* has to do with libav. The most recent libav update might be the culprit here...

I'm using libav-11.2. Presumably alsa-plugins-1.0.28 isn't compatible with that.
Yep, it's also incompatible with libav-11.2.
With USE=-ffmpeg it compiles... For me sound seems to play just fine without it (pulseaudio/alsa).
FWIW, I get this same error for media-plugins/alsa-plugins as well as media-video/mplayer.

still an issue today.
Created attachment 398818 [details, diff] alsa-plugins-1.0.28-libav10.patch I believe this may be the patch we're after - I lifted it from the Debian archive, but I believe it is/was based off of the one in this libav bug report: https://bugzilla.libav.org/show_bug.cgi?id=619 Applied on my systems and it seems to work okay so far, or at least it has cleanly compiled for me for the first time in a while.
Applying the patch has fixed this issue for me.
My apologies, I committed 1.0.29 of alsa-plugins without looking at this bug first. I presume your patch is still required? (From looking at what has been linked, there has been no upstream change)
I confirm that the version bump has not fixed this bug unfortunately
Fails to build for me for quite a while with the same problems. Pushed Luca's patch as: > 06 Apr 2015; Sergei Trofimovich <slyfox@gentoo.org> > +files/alsa-plugins-1.0.28-libav10.patch, alsa-plugins-1.0.29.ebuild: > Applied libav-10 patch from bug #539680 by Daniel Schulte and others. Fixes > build failure for me. Thanks!
