The log, on the other hand, shows that chrome connects and creates some playback streams. It doesn't create any recording streams, however. Either chrome doesn't even try to use pulseaudio for recording, or it (sometimes?) fails to create the recording stream. The strange thing is that earlier you got some sound from chrome, and if I understood correctly, you had pavucontrol open. If you have pavucontrol open, and you can see activity in the mic volume meter, it means that pulseaudio is using the microphone, and usually other applications can't use the microphone at the same time if they try to use the hardware directly, bypassing pulseaudio. Maybe in that instance chrome managed to create a recording stream in pulseaudio? You can check the "Recording" tab to see whether chrome is having a recording stream in pulseaudio. If chrome tries to use the hardware directly, you can set the card profile to "Estéreo analógico Salida" in pavucontrol's "Configuration" tab. That will prevent pulseaudio from using the microphone, so there won't be conflicts between chrome and pulseaudio. If you run chrome from a terminal, does it print any errors in the terminal output? -- Tanu https://www.patreon.com/tanuk
