Blue Iris

I've had my BL 5 configured so when motion is detected, the border of the camera window flashes red and it makes a sound. It has been working great all this time until a couple of days ago.
I noticed I am getting alerted on my smart devices and the camera window flashes and everything seems fine, except there's no sound on the alerts.

I have not made any changes and it all of a sudden just stopped working. If I click Test.. it does sound, but it won't on motion alerts.
It's been 2 days of me trying to figure out what's wrong and I just can't figure this out. The thing obviously works, because the tone sounds when I manually make it sound by pressing Test.
Any ideas of what this can be?

Did you check if it is enabled/disabled on the preceding page, and is the Profile(s) for the alert active for the Profile you are testing Have you made any changes like adding Deepstack ?

I tried setting this up, and found some of the sounds work with Test, and some don't on my BI5 pc. Alarm.wav works every time for me, but "i-demand-attention.wav" doesn't sound at all with Test. Can you try it with Alarm.wav just to rule it out ?

The exact thing happened to me recently. The tone would play in "Test" but not as an alert when the scene was triggered. I played around with it for an hour or more until I discovered that I had inadvertently clicked the tiny "Mute" icon next to the volume slider way up in the upper right corner of the main BI window.



Sometimes you're the dog, sometimes you're the hydrant. I "unmuted" it, pretended that never happened, and went merrily on my way. "Doh-di-doh-di-doh....

Sorta like when my cat used to sleep on the window sill in the sun and then roll off in his sleep. He always had a perfect "I meant to do that" expression.

I think this might have something to do with blue iris working as a service.
The service without UI might have troubles with playing music

Please try to play alarm sound using a script,
first create a script playAlarm.BAT:
This code will play the alarm for 40 seconds

Then, in Camera Settings->Alerts->On Alert->Run a program or script->File->path-to-your-playAlarm.BAT
