Well, another update that probably will be the last one from me, since I'm beginning to really hate ALSA.
Decided today to try to test some parameters; I had left the audio card loaded with VFIO module since the command dump. Today I've decided to retry to use it, so I've removed the VFIO stubs from modprobe, rebooted and... no PCI audio card. Disabled IOMMU to force load the modules (something like this was already seen by me; even when VFIO wasn't asked to bind it, it would bind it anyway), no PCI audio card. lsmod says that the module is loaded on the audio card, however no audio from any PCI devices, even the audio from the GPU. I'll attach alsa-info. Just for reference on your list, when the module was working, I had output working fine, but input crackling. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1801540 Title: Microphone distorted sound on ALC892/1220 on AMD chipsets Status in Linux: Confirmed 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.
