Thanks a lot for the input, Ken! You were right, it is not related to BT, but to the sound devices being added and removed.
I happend to have a Zoom microphone that can be connected as USB and creates a new audio interface (both input and output). Here are my new tests and findings: 1. Plug the Zoom USB device -> it appears in the Sound Settings Output Device and is automatically selected 2. Press Test and check the sound output -> the sound outputs on the internal speakers (NOK) After some investigation using pactl, I found how to fix the issue, for both the USB audio interface and the Bluetooth speaker: 1. Make sure the audio interface you want is connected (in my case, I connected both the USB and the Bluetooth speaker): $ pactl list short sinks 1 alsa_output.pci-0000_00_1f.3.analog-stereo module-alsa-card.c s16le 2ch 48000Hz SUSPENDED 6 alsa_output.usb-ZOOM_Corporation_H2n_000000000000-00.iec958-stereo module-alsa-card.c s16le 2ch 44100Hz SUSPENDED 7 bluez_sink.88_C6_26_1A_9E_AF.a2dp_sink module-bluez5-device.c s16le 2ch 44100Hz SUSPENDED 2. Play an audio stream, for instance a Youtube video. The output should come from the internal speakers, and can be seen in pactl as well: $ pactl list short sink-inputs 10 1 16 protocol-native.c float32le 2ch 44100Hz 3. Ask pactl to move the stream to the desired sink (output); for instance, the Bluetooth speaker: $ pactl move-sink-input 10 7 -> The sound outputs to the Bluetooth device! \o/ However, going back to Sound Settings (where the "Output Device" shows my Bluetooth Speaker) and clicking Test still outputs to the internal speakers.... Do you think it could be a GNOME issue? What should I do next? ** Summary changed: - After connecting a Bluetooth headset or speaker, it shows up in the sound output options but the sound keeps being emitted from the internal laptop speaker + After connecting an external output device (USB audio interface, Bluetooth speaker...), it shows up in the sound output options but the sound keeps being emitted from the internal laptop speaker ** Tags removed: a2dp -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1866194 Title: After connecting an external output device (USB audio interface, Bluetooth speaker...), it shows up in the sound output options but the sound keeps being emitted from the internal laptop speaker To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1866194/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
