Hi all,
I'm trying to use my notebook as a BT transmitter to send music from old analog devices to my BT headphones. Since my notebook doesn't have an Audio In, I bought a Behringer UCA202 that I want to use with an old Bluetooth dongle by Trust.
Playing audio from sistem (youtube) to BT Headphones works, as well as recording audio from the UCA202 with audacity. But I cannot figure how to route the audio in from the external soundcard to the bluetooth dongle. I am using Ubuntu Bionic Beaver, so there is a setting in the audio section of the control panel to select the default audio input and output device, but it seems like if a link between is missing.
Is there an application to do this or a setting?
Thanks in advance.

I'm guessing this is the typical adaptation for such a device, you record the input, then play the recording with a media player. Perhaps a stream media player can pick up the "stream in" and "play out"?

Thank you for the reply. Googling for stream media player bring just application for IPTV and so on... do you know a software that plays audio streams from the pc itself?
