Re: usb microphone on X1 Carbon

Hi,

Thanks for the advice -- I do have a headphone set that works.  However, I needed to get something I could hear/speak from across the room in a zoom yoga class and to keep things as simple as possible, I got a little USB conference speaker/mike.  After fussing a while I figured out that this could be activated by restarting sndiod with the argument -f rsnd/1 and going back to the internal speakers with -f rsnd/0.  It works great!

I really appreciate the help people give me on this mailing list.

Dave

Hi Dave,

According to your mixerctl output, the machine has a microphone input
which corresponds probably to a combined 3.5mm trrs headset jack. If
so, most phone headsets should work.

Assuming the headset works, if the headphones are uncomfortable to
your ears, you could use the headset's mic and the integrated
speakers. Once you plug the headset jack, you've to unmute the
speakers with the mixerctl(1) command (speakers are automatically
muted). Then, if you're satisfied, you could add the appropriate
commands to /etc/mixerctl.conf to make your changes persistent.

Another option would be to use a comfortable USB headset, it must be
class-compliant, most are.

HTH
