But, I understand that what you are doing is trying to record from a mic, and not what is being played by the soundcard. Sound systems in linux consist of two components, alsa, which takes care of low level details on sound devices, and pulse, which sits on top of alsa and handles routing of sound device output to consumers, so called sources and sinks. Both have to be set up correctly in order for sound to work properly. But, if they are set up correctly, you don't need to do anything fancy to use sound. In audacity, you should just have to select pulse as the source, and the recording function would work. So, the first question is, does alsa recognize the recording device you want to use? arecord -lv Is it there? The next question is, what is the default recording device in pulse? If it isn't the device you are trying to record from, you won't get any input out of pulse. I find this easier to see from pavucontrol, in the recording device tab, and it is easier to set the default there also. But it can be done from pactl, I'm just not familiar with the invocation. Once this is set properly, you will be able to get sound in audacity from your input device using pulse as the setting. Alternatively, you can turn off the sound device with your recording device from pulse so it becomes controlled only by alsa, tell audacity to use alsa, and select the actual device that you want to record with. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
