error opening audio device

Hello,

I am using the windows version of Audicity.
When playing a recorded sound I get an error message.
I want to hear it with my Headset (a typical headset you use for webEx, teams or zoom sessions)
How can I resolve the error ?

regards,
Roland

That what the error message says:
Error opening the audio device. Try changing the audio host, playback device and sample rate of the project.

Is your audio device a “Plantronics Blackwire C3210 Mono USB Headset”?
If so, check that the device is capable of playing and recording at the same time.

Check in the Windows Sound control panel (“mmsys.cpl”) that it is set to use a sample rate of 44100 in both the Recording and Playback settings.
(Audacity should be set to 44100 by default, unless you’ve changed it).

yes it is the Plantronics Blackwire C3210 USB Headset but I am not sure of mono or stereo.

Check in the Windows Sound control panel (“mmsys.cpl”) that it is set to use a sample rate of 44100 in both the Recording and Playback settings.
(Audacity should be set to 44100 by default, unless you’ve changed it).

I checked the Windows sound panel (mmsys.cpl) and put the sample rate to 44100 (it was 48000) for play and recording
unchecked button “allow apps exclusive access to the audio device” for play and recording too.
rebooted the computer, but same error message still appears when playing.


:confused: I am at a loss… but here are some things to try…

  1. Check that the Audacity Project Rate (Hz) is 44100, and that the Track Sample Rate is 44100.

  2. Ctrl-A, then Tracks > Mix > Mix Stereo Down to Mon; then in Device Toolbar, select 1 (Mono) Recording Channel.

  3. Try both MME and WASAPI

  4. Try re-booting.




Can this be changed to: “2 Kanal”?
