Hey there, I use OBS Studio 64-bit.
So I used the NightDev Tip Alert through Steamtip and integrated it through a browser source and it works perfectly.
I use Streamtip Alerter for all of my donation sounds. For some reason, today, and without touching a single thing, my sounds for donations do not work at all. I checked the OGG sound files and the files are linked correctly. I preview the sounds in Streamtip Alerter and they work perfectly fine. But, for some reason, when a donation comes in, the alert will show in OBS, but the sound will not play at all. I checked all sound settings and made sure Streamtip wasn't muted or anything, the sound in Streamtip Alerter still works but will not trigger during an actual alert. I reset my tip alert's access token to see if that would have fixed the issue, but sadly it has not.
