No, it will not change anything related to the issue, it only could make a difference, if you would hear issues already when monitoring the audio signal. >Linux version 4.18.0-12-generic The issue could be related to the load and real-time priorities when recording audio. You could install https://packages.ubuntu.com/cosmic-updates/linux-lowlatency https://packages.ubuntu.com/cosmic/rtirq-init after installing rtirq-init in /etc/default/rtirq edit RTIRQ_NAME_LIST to RTIRQ_NAME_LIST="usb" then restart the computer to test if this makes a difference. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
