Just tested, the voice recorded is OK. But there is some difference between 19.04 and 18.04, after installing 18.04, the aplay/arecord default device pulseaudio, while after installing the 19.04, the aplay/arecord default device is hw sound card.
Please install 19.04 to a different machine (not x1 carbon), let us see if the default device will change to pulseaudio or not. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1824103 Title: The vioce which recored by Internal microphone gets noisy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1824103/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
