(Quick Note; I’m extremely new to Linux so some of my terminology won’t be spot on and I’m not too sure what I can provide to help you guys help me so please let me know what I should provide)
I was recently watching a tutorial on how to do a single GPU pass-through for a VM, and during it one of the first few steps was to enable my IOMMU, I tried following the tutorial through terminal but was unsuccessful.
I then went for the forums and found out you can just enable your IOMMU through BIOS. So thats exactly what I did I went to BIOS and enabled IOMMU
After booting back up my audio / speaker icon was shown that it was muted after clicking on it no audio devices showed up like my entire audio tab in system settings is blank.
Ok i figured it must’ve been a bug, so I went back into BIOS disabled IOMMU and my audio was back to normal and everything was working fine, after attempting to renable IOMMU the same thing happend and my audio devices aren’t popping up / there is no audio
I’m not sure if I should take this problem head on or if i should find a way to use the terminal to enable IOMMU. For those wondering I was watching SomeOrdinaryGamers’ video (I can’t link it but it’s called “I Almost Lost My Virtual Machines…” -Uploaded on March 16 2021
And yes at around the 6:52 mark of the video when he is typing “intel_iommu=on” I did change it to “amd_iommu=on”
after doing the check sudo dmesg | grep -i -e DMAR -e IOMMU to see if it was enabled like shown in the video I got completely different results (I will probably reply with it because I don’t know if my formatting is good or not here since I don’t use forums like at all)
I use Manjaro KDE
I have an AMD Chip
I am using Corsair Void Pros as my headphones
I have enabled and disabled and yes the issue happens when I enable IOMMU through BIOS
Please let me know what other info I can put here!
Edit: added sudo dmesg | grep -i -e DMAR -e IOMMU
