Hi all,

I have a USB C headset.

I am setting it up, so it’s plugged into my Linux box, so it can listen to music, and make calls, etc from my phone, via bluetooth.

Then I don’t have to keep unplugging my headset and plugging it into my phone.

Also so I can record directly to the Linux machine, that is broadcast from my phone.

But, how can I intercept the Bluetooth audio, and record it?

Thank you.

    You probably have PulseAudio somewhere in your audio chain.

    If you open the pavucontrol program, it’ll show you PulseAudio controls.

    If your mic is enabled, you’ll see it in the “Input Devices” tab. Most audio recording programs will let you choose the source you want to use. One of the devices here will be the “default”, and you can click the checkbox next to it to select that.

    I (very recently) learned from a problematic Sennheiser Momentum 4 that Bluetooth headsets can have two, separate, mutually-exclusive modes, one for high-definition audio, where they act only as headphones, and one where they can act as a combined mic and headphones, but have lower audio quality. I don’t know if that affects your headset as well. However, if it also applies, then your headset might be in “high definition audio” mode, and it won’t have an entry in the “Input Devices” list. Instead, click on the “Configuration” tab, and set the thing to what is for me “HSP/HFP” – this is the lower-quality headset mode. Hopefully then you’ll see an entry in the “Input Devices”.
