No response

Expected Behavior

Turning ON monitoring and output and listen no latency.

Current Behavior

When I turn monitor and output ON in Advanced Audio Properties, the latency is OK at the begining but after 5 minutes, the monitor gives some big latency. Tested on pulseaudio.

Steps to Reproduce

1. In audio mixer, right click on your audio input source and choose Advanced Audio Properties.
2. Select Monitor and Output in Audio Montioring.
3. Wait 5 minutes, sound loopback takes increasing latency permanently.

Anything else we should know?

I have the same issue, capturing video and audio from another device is increasing audio latency across time, I'm currently using Debian 12 Bookworm and capturing with PulseAudio.
