Version: 2.1
I'm using an Intel NUC connected via HDMI to an ASUS monitor. Up until the libevent update, I could plug headphones into the monitor and listen to music, but that stopped. It is still possible to hear music via the NUC jack. The latest updates were libevent-core-2.1-7t64:amd64 and libevent-2.1-7t64:amd64 according to /var/log/apt/history.log.
I'm actually running Devuan, but those developers told me: "However, src:libevent is not forked in Devuan and we use Debian's packages directly without recompilation. So, in principle this should be reported to Debian's BTS."
