Most reports mention ALC1220, but the same bug occurs in older AMD systems also.
E.g. it occurs on a 2014 system by Dell, AMD chipset, AMD G-T48E CPU, ALC269VB, with Linux 4.19. Whereas the microphone of that system works OK with Windows 10. **** List of PLAYBACK Hardware Devices **** card 0: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: SB [HDA ATI SB], device 0: ALC269VB Analog [ALC269VB Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 **** List of CAPTURE Hardware Devices **** card 1: SB [HDA ATI SB], device 0: ALC269VB Analog [ALC269VB Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1801540 Title: Microphone distorted sound on ALC892/1220 on AMD chipsets Status in Linux: Unknown Status in linux package in Ubuntu: Incomplete Status in pulseaudio package in Ubuntu: Confirmed Bug description: Not sure if I'll report this upstream but there is definitely an issue with microphone recording on my desktop, this is not happening on my laptop which has a different codec.
