Gradio stopped working and only reports: pa_stream_write() failed: invalid parameter

[bentolor]

Expected Behavior

Suddendly Gradio no longer starts. I lately played a little with my sound configuration but reverted to the old state. Sounds work flawless in othter apps

Current Behavior

On playing a station the status line only reports pa_stream_write() failed
