BAT supports 5 working modes: loopback, single line playback, single line capture, local and driver testing: frequency detection, roundtrip latency measurement and noise detection. It used to be so that during startup the latency was rather random, and it would take a long time before the module would adapt to the requested latency. I start bluetooth, ofono, and pulseaudio by using the following W: [pulseaudio] module-loopback. This can be worked around with a null sink and a loopback which will capture audio fine. There is a related redhat bug log[1] > and a kernel one[2], that suggests disabling the wireless interface > might avoid the problem. Use a second terminal emulator for cava and set the font size to 1. ) Referenced during the discussion were the Wine audio latency tests and fixing a PulseAudio loopback delay.
