Description
crabbed halo ablution
2019-11-21 11:02:39 UTC
This has hit me on an arm and amd64 system. It's pretty bad and it's going to affect a lot of users.
It seems to be a change in alsa-lib. 1.9.1 is okay. 1.2.1 and 1.2.1.1 are not. The aforementioned PulseAudio patches were already applied in 13.0 so it's not that.
This is what I get from PulseAudio's config.log:

Okay, I think it's these. New includes are needed. https://git.alsa-project.org/?p=alsa-lib.git;a=commitdiff;h=5c88b183718ce3df11bc4753c76d95f3e9de6c7e https://git.alsa-project.org/?p=alsa-lib.git;a=commitdiff;h=cd4b07ffbdd4612989e63800528b18efe0039ad9 CC'ing alsa-bugs@g.o as this is serious and it's probably going to affect more than just PulseAudio. I gather the main alsa-lib maintainer, Polynomial-C, is somewhat unavailable right now. In the mean time, I tried adding some includes to use-case.h but the list kept getting longer. I'm not sure if that's the right approach in any case. Upstream may say that you're expected to include other headers first/instead. PulseAudio could therefore add alsa/asoundlib.h to its AC_CHECK_HEADERS call so that all the headers are included before use-case.h is checked. I imagine they're going to stumble across this very soon if they haven't already and they'll decide what the right course of action is. A short term work around for us is passing ac_cv_header_alsa_use_case_h=yes to PulseAudio's econf call. I suggest we just do that for now. Technically it should be a revbump as the problem doesn't appear until runtime. I went ahead and submitted a fix to PulseAudio. We'll see what they say. ALSA has now fixed this instead so I closed the above merge request. I don't know when it'll be released though so maybe we should apply the patch now. https://git.alsa-project.org/?p=alsa-lib.git;a=commitdiff;h=1a4b362115b5e1bb4f5b888919ffd11736adbf0c Patch confirmed working. First apply to alsa-lib, then recompile pulseaudio before it works. When it is applied to the tree, we should revbump pulseaudio also.
