Mic issues

[Matthew M. Dean]

Just came across 2 issues with OBS 27.2.3.

• Push to Talk doesn't work unless OBS is the active window, its completely unusable.
• It shows HDMI audio for Desktop output but it's recording the PTT mic instead. oops.

After 30 min I gave up using PTT and used the hardware button for my mic, I noticed the desktop volume went to zero. Under properties it shows HDMI Audio RX 580. I listened to my stream and it's not recording the game audio. its recording the PTT muted microphone via Desktop Audio without filters. Thankfully there wasn't anything embarassing and I managed to discover it within 30 minutes.
To fix I simply restarted OBS. I checked the previous stream and it worked correctly.
Something to do with suspend without closing OBS maybe? A PulseAudio issue? I still can't figure out how to set HDMI as the default sound device after reboot.
Before each stream I'll be sure to restart OBS if it's running and check the audio now.

Ubuntu 22.04 LTS.
edit: its in the log. The UI is misleading?

It should read
