So I guess it could be a software problem (maybe linux-image oder linux-modules?). --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.14 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: joerg 821 F.... pulseaudio CasperMD5CheckResult: skip DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2020-03-14 (291 days ago) InstallationMedia: Xubuntu 19.10 "Eoan Ermine" - Release amd64 (20191017) IwConfig: enp0s25 no wireless extensions. lo no wireless extensions.
