Pulseaudio crashed randomly while watching a YouTube video in fullscreen. When crashing the last 1 second or so of audio looped for a few seconds, then cut out. I am using PulseEffects as well, which crashed around the same time. Whether that was the cause or a result of the PulseAudio crash is unclear.

I am using Bionic because the video drivers for my AMD Raven Ridge iGPU are not supported by earlier versions.

Status changed to 'Confirmed' because the bug affects multiple users.

[Daniel van Vugt (vanvugt)]

It looks like commit 4762aa45d9ea2f5146a135eda6b840bf3964b317 is the fix here. Not sure. It's not in any official PulseAudio release yet.

[Sebastien Bacher (seb128)]

@Daniel, unsure that commit fixes it?
(https://gitlab.freedesktop.org/pulseaudio/pulseaudio/commit/4762aa45 for reference/easier browsing)

The commit message states
'The bug had no impact because there is only one caller of pa_make_fd_block() in poll-win32.c'

Also the code bt here indicagtes it assert on
  194: pa_assert_se((v = fcntl(fd, F_GETFL)) >= 0);

where the code change from that commit is a few lines further in the function

[Daniel van Vugt (vanvugt)]

Yeah it doesn't matter it comment #8 is wrong here. I was going to wait till the commit is released and then confirm the crash has stopped happening.
