Hallo,
vesuche seit einiger Zeit skypeforlinux ans laufen zu bringen. Die Empfangslautstärke von unter 40% erkennt skype nicht
Bei der Einstellung des internen Mikrofons habe ich festgestellt, dass oberhalb der Empfangslautstärke von 40-50% ein starkes Rauschen und Kratzen auftritt.
Test mit arecord -f cd -d 10 test-mic.wav und aplay test-mic.wav
Mein System:
Lenovo ideapad 320-15IKB
CPU Intel Core i5-8250U
Kernel: 5.6.6-arch1-1 x86_64
KDE Plasma 5.18.4 tk: Qt 5.14.2 wm: kwin_x11 dm: SDDM
AUDIO Device-1: Intel Sunrise Point-LP HD Audio vendor: Lenovo driver: snd_hda_intel
v: kernel bus ID: 00:1f.3 chip ID: 8086:9d71
Sound Server: ALSA v: k5.6.6-arch1-1
Die in den Foren vorgeschlagenen Einstellungen mit alsamixer brachten keinen Erfolg.
Die im engl. ArchWiki vorgeschlagenen Problemlösungen ebenfalls erfolglos.
Hier noch die Ausgabe von pacmd list-sources

Wer kann mir weiterhelfen? Viellleicht ist nur eine Einstellung falsch?
Für eure Bemühungen; Vielen Dank im Voraus. Bleibt gesund!
