I bought a new wireless headset: an EPOS H3PRO. I’m connecting to it via its own low-latency USB dongle, so no Bluetooth.
The headset will function fine as an audio output OR an audio input, but if I want to do both at the same time things go wrong.
For example: I boot the PC, I play some music, and I try to record my voice with something. It won’t work. It’ll just freeze.
And now the other way around: I reboot the computer and use the headset’s microphone first, it will record fine. But if I then want to play something back through the headset, it won’t do so.
Here’s some info on the USB dongle & the driver it’s using on my system: https://linux-hardware.org/?id=usb:1395-0303&dev_class=01-01-00&dev_type=sound&dev_vendor=Sennheiser+Communications&dev_name=EPOS+H3PRO+Dongle&dev_ident=618ea
