New version available upstream. I just copied alsa-lib-1.0.9_rc2-r1.ebuild to alsa-lib-1.0.9_rc3.ebuild in my overlay and removed both epatch calls in src_unpack. As far as I can see they are both fixed upstream. alsa-headers I didn't change anything in, just moved to overlay and renamed. Both emerged fine and seems to work fine as well. Finally the distortion introduced in 1.0.8 is fixed! I haven't tried the other alsa-*-1.09_rc3 packages yet. Reproducible: Always Steps to Reproduce:
Created attachment 58032 [details] alsa-lib-1.0.9_rc3.ebuild Just removed epatch calls that, as far as I can tell, are no longer needed.
1.0.9 final is out and in the tree.
