Hello @ferranmc,
Thanks for the update.
I am glad you were able to get pulseaudio to work from another user.
In the related post I also mentioned that an empty output from pactl list cards can also be caused by a device tree misconfiguration.
You should be able to still use bluealsa together with pulseaudio using the module-alsa-sink, but let’s continue that conversation on your new post about this specific topic.
Best Regards,
Bruno
